Jeep ABS wheel speed sensor circuit (Staten Island Ep 9.3)

[@wyattoneable]

It is a lot of work to chase down one simple wire but your one of the best! I've always enjoyed your approach to solving a puzzle.

[@chrism5433]

Some bosses don't understand how long it takes lol

[@markwatson9816]

Ivan - I used to teach electronics. For the best long term repair you should clean off the residual flux with isopropyl alcohol before putting the heat shrink on it. The flux will keep working creating its own green crusties. This recommendation is from the standards for High Reliable Soldering practices - NASA STD 8739 is the one we used. Having whined now the good comment - your videos like Keith's and Eric O's diagnostic one are excellent excellent. I don't always like the handheld camera shots but your voice over explanations make them live and in the moment.

[@for2utube]

Mark Watson Thanks for the tip. I'm 55 and didn't know that.

[@pauldavis5075]

I admire your patience locating that one.

[@alexanderkasyanov4946]

even though my issue was just a faulty WSS, i still learn a lot from your video! thanks for sharing!

[@baxrok2.]

Great tip on finding a break Ivan. I have the same soldering iron. After you're done soldering leave the iron on and use the side ports on the iron to shrink the tubing. Works perfectly! Thanks!

[@PineHollowAutoDiagnostics]

Why didn't I think of that? Thanks for the tip John :)

[@ericcorse]

Don't know how you could think with all that racket and "music". Well done.

[@michaelmobilautodiagnostic6705]

Great case study Ivan! I'm enjoying the new material during the flood here in Houston Texas. Keep them coming brother!!!😝

[@PineHollowAutoDiagnostics]

I heard you guys got like 4 FEET of rain?!? That's messed up!

[@michaelmobilautodiagnostic6705]

😔 luckily it hasn't got that high around where I live I just got like one foot of water. It barely started going into the garage. My sis just got rescued after being stranded across town for 3 days. The water got to roof top level they lost mostly everything. Good thing is they are safe now here with us. It's just a waiting game now until the water goes way.

[@dcrickerson7611]

Nice work Ivan. Thanks for bringing us along.

[@theoldwizard998]

Very nice diagnosis and repair ! I think I need to make one of those "helping hands". Cheap and effective. You almost wonder if that is a low spot in the harness if you should leave a gap in the tape for water to drain out !

[@robinsonsmotorcycleandauto3929]

Seems a Lot of people struggle with electrical. I am trying to gain some shops doing there diagnostic work as I enjoy this kind of stuff. Great Job Ivan and your right it just takes time.

[@MrLarryC11]

What an awkward place to solder and wrap in! Great video.

[@randytheapplianceguy8838]

"You will survive, then walk right out the door ".. I love the disco groove Ivan. I prefer ABBA while I'm working. 😎

[@johnbleau9379]

It was in a spot that likes to collect slush and snow, I've pulled them inner plastic fenders apart to find solid bricks of ice inside. That is likely what caused to corrosion in the harness. Not sure why the harness was looped so low in that area. But good job cutting the problem in halves till you finally found it.

[@dg98adams]

It would make your solder flow better if you use electronic soldering paste (not plumbing solder), and a butane solder iron gets plenty hot enough but tinning and paste is crucial. Great TS

[@richardcranium5839]

lol gloria gainer's "i will survive" playing at the same time you found the problem. how that for timing?must have originally been a rub through. suprised that harness is allowed to flop around in there like that. one thing i have found thru the years is that a solder joint wt a point of flexation will often break. sometimes its better to put in a longer stretch so it wont be flexing at the joints. looks like that one will live long enough, thanxs for taking us along

[@NoWr2Run]

That's amazing NO WONDER A DIY CAN'T FIND PROBLEMS WITHOUT ALOT OF TECH. KNOWLEGE & A EXPENSIVE SCANNER.

[@DaveSender66]

Looks like you're getting to be a regular diagnostic technician on the Island. KZbin live and you don't have to do any film editing. Nice find Ivan!!!!!!!

[@qik65]

Great vid. I like the way u break everything down

[@virtualviewer61]

Enjoyed watching this repair and troubleshooting, Thanks for showing this.

[@mid-thumbautomotive9716]

Nice diagnosis Ivan!

[@haywardsautomotive6156]

Nice diagnosis & repair Ivan!

[@karlbuttler]

Ivan; those "Mechanics" that just replace parts keep you in business, and bring a lot of shame upon them selves....

[@davidsawyer1599]

Question. Would the repair not have been easier to accomplish if the harness had been disconnected? It appears as though you wpuld have had more area to work. Thus facilitating a better solder joint. My two cents. Ivan you always do top notch work.

[@Dtapia63]

David Sawyer and removing the wheel, it was already on the lift.

[@NewLevelAuto]

I wake up to this one . Sweet

[@mattw1393]

New Level Auto hi Keith. The live Mercedes you did earlier, is that gone forever? I couldn't stay and watch all of it.

[@PineHollowAutoDiagnostics]

You wake up at 4am?!? I only went to bed at 3am haha

[@NewLevelAuto]

Matt W it was temporarily taken down. Be back soon

[@smalltalk.productions9977]

impressive! thanks for the effort and the sharing.

[@lorrinbarth1969]

I think I would have left a little gap in the electrical tape at the low point in the harness. Otherwise, always wet.

[@themechanic6117]

Great work,sometimes you just gotta make some holes.

[@ralfsautomotive]

If you ever get a chance, and I'm NOT saying you should use it!! Try out the Super 88, it is still real flexible but adds about a .0015" in thickness and is abrasion resistant. Some areas I use it but for the most part the 33+. Downside of course being the price LOL.

[@PineHollowAutoDiagnostics]

I actually do stock Scotch88 as well! Beefy!

[@mikeandre9903]

Great information great video we have a 2011 Jeep Compass and we do not know if that is exact problem or not but if it is this video does help👍👍

[@BlindBatG34]

Do Chrysler products exist just to keep mechanics from starving?

[@SmittySmithsonite]

I think the Big 3 exist for that sole purpose!

[@jdtractorman7445]

Not just the big three, but all manufacturers. My parents have a Kia that is getting a new engine put in it. Don't matter what brand you have they all have problems.

[@SmittySmithsonite]

Yep - par for the 21st Century course, unfortunately.

[@throttlebottle5906]

whoops, not bad soldering @ Ivan, I mostly dislike the gas heated devices, lack of temp control, best bet it watch and touch them with solder, when it starts to melt fast, underside touch the wires, tap solder to iron/wire meet point, watch closely, it will start to melt/flow, move solder to top of wire and iron back and forth following solder ( heat fast, flow good and remove)

[@tomdewey9907]

Ivan, you should definitely add rosin core flux liquid or paste first when doing wire solder splicing especially with somewhat old crusty wires.

[@throttlebottle5906]

always cut back the "crusty" discolored wire to clean copper appearance, unless you know for sure that it's a 1/2 to 1 yr vehicle :)

[@TheThomaswastaken]

That alligator clip to hold the wires will be implemented in my future repairs.

[@Badgertronix]

Good work. Who'd have thought to fix the right rear you'd be working at the left front 😂

[@PineHollowAutoDiagnostics]

I KNOW RIGHT!?! That's why it took a while to track down haha Go figure!

[@jetjazz05]

That liquid electrical tape, that's literally just plastidip. It's made by Performix, the orignal "Plastidip" product. Works great though, if you ever have to cut a harness or do a repair that stuff is incredible. Bought a car with a shorted wire to the car's ignition coils (they all come on one big pack), the car would just stall out randomly. Took me a long while to figure out what was happening there, the problem was never there... until your car stalled. Anyways it was an exposed wire, I put the liquid electrical tape on it, coated it again the next day, then rewrapped the harness. It sort of looks like someone had the harness apart and they cut the insulation away on accident using a box cutter.

[@blockbertus]

The mysteries of Staten Island. I always have to wonder "How?!" when I what these. :D Keith must be sitting on a goldmine over there. :D

[@PineHollowAutoDiagnostics]

Whenever I get bored in Pennsylvania, I just head East to Keith's goldmine of automotive diagnostics :D

[@deantubeful]

They certainly don't design for easy tracing with modern wiring harnesses. Not sure how long it took you ? But good job Ivan.

[@johnmckamy6398]

question 1 , Is that shop going to eat their mistake? question 2 how do you concentrate with all that loud music? doesn't seem like a very professional atmosphere . but good video Ivan

[@supercoupe6288]

good work Ivan

[@Automotive_Solutions]

You made it look easy. Good job.

[@jetjazz05]

There's Super 33+ and Super 88 Scotch tape... the Super 88 is thicker if you're worried about possible abrasion or just want a little extra stiffness on your wiring repair... 90% of the time the thinner 33+ is the way to go through. Anyways I live in Florida, that Scotch Super is the only stuff that'll stay on for more than 6 months. Everything else just turns to a gooey slime and leaves the glue residue allover and it's incredibly sticky, but thankfully this tape is good up to 221 degrees and can handle just about anything.

[@PineHollowAutoDiagnostics]

Yes I've gotten burned by the cheapo "automotive electrical tape" before...never again!

[@AP9311]

That's weird....almost similar!!! Eric O did that Jeep Patriot with abs wheel issues.. wow. Uppity trying to copy him? Lol hahaha

[@stephenlawrence4362]

You are close to a genius

[@Shandybrother]

So does the customer have to pay for the first miss diagnosis of the wheel sensors?

[@DDescalchuk57]

What about the same issue dodge 1 ton truck rr wheel speed sensor circuit fault but I get a signal and it picks up the speed of the wheel when I watch the live data on the scan tool

[@ozzstars_cars]

The tiny solder wire holder you have worked great. I know I have a pair of spare nipple clamps somewhere around and need to make one of those holders :) Btw, awesome find!

[@PineHollowAutoDiagnostics]

nipple clamps....can you send me a link? LOL

[@ozzstars_cars]

As soon as I edit and upload the video you will be the first to see it Ivan! lmao

[@michaelkane732]

good work as always

[@ahmedbig1356]

Nice work

[@JD-iu3vi]

Ivan, Do you work for Keith now?

[@lionellavallee1919]

Would left rear be in same location ( wires)

[@arsinoeivlostprincess4228]

I can see slush and water getting up there and freezing and creating a heavy block that will pull on that bundle of wires or in falling off damage the wires.

[@Y10Q]

Why would OEM wiring have a cut in it??

[@TheStwat]

That insulation tape looks like it was done by a 5 year old ! I can't believe that is OEM. Shocking quality.

[@robertf4572]

Where did u get the miners headlamp? What model? I can't find a decent one.

[@PineHollowAutoDiagnostics]

"Foxelli". They last about 6 months but for 15 bucks on Amazon not a bad deal.

[@SmittySmithsonite]

Divide and conquer! It's a pain in the bum on modern vehicles, but it works. :)

[@westtexas501]

when doing an electrical diag like this how do you charge customer/shop ??

[@charlesmiller5078]

Does shrink wrap seal out water ?, I sure it helps, but waterproof dont think so. Bad design overall. How cheap can they make them, pretty cheap apparently. The music reminded me of Dancing at the Disco, not a good memory.

[@PineHollowAutoDiagnostics]

Hi Charles, the more expensive shrink wrap with the sealant inside sure does a good job. That is the only type I use.

[@charlesmiller5078]

Didn't know they sold that type, goes to show what I know. They should use the type of cable we used in Communications work, it was hard to get into with a hatchet. They should protect it more when its in a wet area. But we want to keep Ivan busy, so go Chrysler.

[@TheThomaswastaken]

I am wondering why these shops call you. I have heard scanner danner gets called out to investigate complex issues also. How do you get to the point that mechanics call you when they can't solve a problem? My mechanics broke my brakes, and offered a possible solution for only 750 dollars. Why would I pay someone when they aren't positive of the solution?

[@Micko350]

Ivan, it's Heat Shrink my friend, heat shrink! Good video bud! Now you just need to pronounce SOLDER correctly! 😆

[@movingupautodiagnostics8645]

Wow, a very expensive open wire for sure... And who the heck dislikes a video of you fixing cars while listening to Donna Summer?

[@defendermender4959]

What piercing probes do you use?

[@swfloridacarguy1987]

Ivan, how do you concentrate with all the background noise.

[@PineHollowAutoDiagnostics]

It was tough!!

[@raymilligan9556]

the green crusty's never sleep!

[@TheThomaswastaken]

I might be overthinking this, but you probably shouldn't have wrapped that harness up watertight. Now the water cant get out. It's always going to find a way in.

[@Micko350]

The Thomas it's behind a Guard Liner?

[@rrmech11]

Great job

[@daquanbrown7886]

Part number on that srink wrap?

[@wtfman5313]

Did the customer pay for the unnecessary parts? Just curious.

[@PineHollowAutoDiagnostics]

Not sure...

[@gianfrancoa]

Hoopty_ Medic most likely the customer paid for the sensor the two hubs and Ivan's repair

[@wtfman5313]

gianfrancoa - The shop should eat it. The customer trusted them fix what was wrong, NOT what wasn't wrong. Friggin bullshit. I don't understand how these shop owners sleep at night.

[@gianfrancoa]

Hoopty_ Medic agreed, but unfortunately most shops can get away with murder, specially if the customer is not savvy enough to question why he's charged with a hub a sensor and a wiring repair all three at the same time.

[@Graham_Wideman]

Hey +Ivan, your description of the sensor signals at 1:06 kzbin.info/www/bejne/bGaYmaGljtual80 is a bit off, though of course you nailed the problem regardless :-). That's not YL/Grn = ground and DG/LB = sigal. Instead, as the schematic shows, it's DG/LB = Batt+, and YL/DB = signal. A scope across those two wires will show a square wave voltage with levels of say 12V and 12.8V. (This implies hooking scope ground to the signal, which invites problems unless the scope has independently floating channels.) Those odd-seeming voltage levels are the obtuse side-effect of the sensor sending a _current_ signal, which ends up generating a voltage relative to ground owing to a resistor-to-ground in the receiver (ABS controller). Explanation: This type sensor has only two wires, with one side tied to Batt+. Mysteriously, the signal voltage takes on two rather oddball-seeming values. Not zero to 12V, nor zero to 5V, nor even zero volts to anything. So this is almost certainly a sensor which communicates by sending one of two different output currents. The receiving control module contains a resistor to ground, and reads the voltage that results from that signal current passing through that resistor. This mode of communication is known as a "current loop" configuration... current flows from the ABS unit along the "12V" Batt+ wire to the sensor, through the sensor, and then back along the signal wire to the receiver, where there's a resistor to ground, across which a signal voltage results. The sensor sends information by regulating the amount of current, in this case to one of two values. The current loop arrangement has two benefits: 1. Interference from electric or magnetic noise affects both wires equally, with an overall effect that cancels out. So less signal degradation from interference. 2. Makes it easier to design a system that has electronics in the sensor, yet uses just two wires. Almost certainly, this module contains a chip like the TLE4923, data sheet here: media.digikey.com/pdf/Data%20Sheets/Infineon%20PDFs/TLE4923.pdf. See page 17 for the likely connection arrangement. Table 4 on page 11 (IS) shows that the low current is 4.1mA (+/- about 1) and the high current is 10.5mA (+/- about 2.5). And minimum ratio between low and high of x2. (These current signals are in the range of the "4-to-20mA" signal convention commonly used for process control in industry.) Eric has a video kzbin.info/www/bejne/aJmap6iNhcZ8na8 of this kind of signal. Looking at 3:36 of that video, the resulting voltages at low and high are about 0.85V and 1.7V (ratio of about 2). So that corresponds to a receiving resistor (RS) of 180 ohms like in the datasheet, with the sensor producing (permitting to flow) 4.7mA and 9.5mA, which is in the range shown in table 4 for IS. The sensor's block diagram appears on page 7. The "output signal" of the device is the amount of current flowing from the pin 1 terminal to pin 2. In this ABS application the VS terminal pin 1 is connected to +12V, and the output is the amount of current (4.7mA or 9.5mA) that the chip allows to flow through from pin 1 to pin 2. Don't be misled by the label of "Ground" on pin 1. In this ABS application it's the output wire. Control of (most of) the current is performed by the variable current source element, shown on the block diagram toward the right as a circle with arrow. In this application the word "source" might mislead -- it just controls the amount of current allowed to flow, ultimately from the VS +12V terminal through to the "ground" terminal, which, as I mentioned, is used here as the output signal. The block diagram also shows apparently two raw hall sensor devices, whose outputs are amplified. The "Schmitt trigger" is a device to compare those two values, and make an on/off decision. The "Schmitt"-ness means that the comparison is done with some amount of hysteresis, to avoid oscillations that might result if the mag wheel is at some intermediate position where the hall sensors read approximately equal readings. More explanation in the blurb on page 8. The data sheet also tells that the TLE4923 has its own built-in regulator for internal use, and can operate properly down to 4.5V across pins 1 and 2 of the chip (and up to 18V). Adding that to the voltage that the current will cause at the receiver, that means the positive side supply can be any voltage from about 6.5V to 18V, and the chip will still produce the same two current levels, and thus the same two voltage levels at the receiver.

You need to use waterproof butyl tape on those wires. Vinyl tape is not waterproof.

[@jetjazz05]

That crusty ass "repair" looks like something a punk would do to add a light bar or something. They just stabbed wires until they found 12 volts that came on with the key under there and wired the lights to the bumper or something. Reminds me, I own a stable of Saabs basically, got a 2004 9-5 last fall... the EGR valve was broken, and someone had cut the end of the harness off for the old one and put the end of an Audi EGR valve on it! I actually used the stock crimped terminal ends and put them into the proper (JPT terminal) connector so I didn't have to butcher the harness anymore than it already was. The last foot of wiring doesn't match the colors that's in the WIS for Saab, but I'll know what's been done to it, I doubt it'll have another owner after me anyways. But yeah since I had to get a new EGR valve there was no way I was going to order it with the Audi connector, I ordered the connector and the valve for that vehicle just in case someone in the future is working on it (and for my own sanity if it fails again).

[@HUBBABUBBADOOPYDOOP]
