MAZDA RX-8 ABS LIGHT CHECK ENGINE LIGHT DIAGNOSIS & FIX

[@foxwithtubesox1075]

Honestly, this started out being a bit overwhelming, and beyond my level of understanding; but the way you explained everything and followed your logic was awesome to watch. Thanks so much for sharing these videos and imparting some of your knowledge.

[@donnguyen6556]

My SUV have no communication with CAN I need your service;where are you now?

[@PaulysAuto]

One of the things I admire about your videos is you take the time to explain things for beginners. Great job as always...nicely done! Take care of yourself brother God Bless 🙌🙏

[@Eremon1]

You can tell that Mazda designed this car to be serviced by one of their own technicians and not the backyard mechanic. Eric, once again you come to the rescue of another car. Well done.

[@billmonroe8826]

And All Data doesn't do anything to help that either.

[@Eremon1]

@@billmonroe8826 I would think that the only information All Data could rely on would be that of the manufacturer, which in this case clearly wasn't useful. I think the RX-8 is universally hated by the car community with the exception of it's small fan base. I've never driven one or worked on one myself.

[@pollcrazy]

As a electronics technologist I love the troubleshooting! Keep the videos coming.

[@highboymountaingrow1117]

Bro…you’re the frickin best channel to learn from. Thank you man.

[@fredproctor6973]

Should get yourself one of those quick pop up canopies for when your on-site at a customer's and outside, an 8x8 would be perfect to keep the hot sun off you.

[@boomalaki23ii45]

Love how you take the time to explain your thinking while looking at the wiring diagrams. Some people may find it dull, but I think It is so valuable to be able to hear the process of problem solving in action. Great video.

[@PauloJRSantos]

Eric as one thing that is he's only! Exactly like you say, time to explain the thinking while looking a diagram!. It's very pleasant.!!!

[@JimmyMakingitwork]

The diag flow chart from Mazda on this one reminds me of those repair procedure descriptions that say, “remove screws, lift out unit. Installing is the opposite of removal.” As if you looked the process up for that level of information. Nice work. I once had a Pontiac no start because of an ABS module. Eerily similar.

[@sanjivpatel4016]

Absolutely brilliant diagnosis! I never knew that the ABS module had an alternative communication line to the DLC.

[@ADVANCEDLEVELAUTO]

Neither did I. Thanks for watching!

[@htownblue11]

Boys and girls, here is a great example of following a diagnostic process, and not just guessing based on a OBDII code. We can all learn something here by this example. And without a known good waveform to compare it to, it is the correct diagnosis or next step in my opinion. And I thought you were an H Town boy like myself. If I ever have a difficult diagnosis I know who I’m calling! Good stuff as always.

[@jamesrudolph9054]

Eric , your level of logical interpretation is mind blowing , it is a car that the manufacturer would rather repair than to have you do it

[@PauloJRSantos]

Hi, it's always good to see you in action! You should change profession, you should teach your knowledge. It's a real pleasure to see and learn of your videos.

[@calebcharles9074]

I’ve never understood wiring diagrams until you broke it down I used to think this stuff was super intimidating but I will continue to watch your approach and the ways of thinking needed to really find the root cause in a trouble car

[@superskylinerR34]

Great Job isolating the problem on a vehicle that the problem was hard to identify!

[@Garth2011]

Good diag process. Those ABS modules are usually faulty from cheap solder processes. Solder cracks and then hot/cold temperatures affect function. Very difficult to pin down unless a mechanic does what Eric has in this video. You would think the modules would have an LED on them that lights up when the module fails. The DTC's in this case where not a lot of help.

[@GeorgeMalonedj]

I've been waiting for a vid all day from you!

[@outofthinair1]

I kinda like it when you geek out ... Great case study BRAVO !

[@The_Redkween]

This was amazing diagnostics work. The funny thing is, I feel like if you hadn’t gone back to explain the CAN schematic to the layman viewers, you might have missed that separate connection wiring for the scan tool. :). I notice, as a technical trainer, that I learn a lot while I am teaching. Congratulations on that find. If you are a nerd, so am I. That feeling of triumph is addictive and the reason we do what we do

[@steveharrigan1296]

Great catch noticing that second comm line on pin 7. and removing it to see you were right. Great Job. this was a tricky one!

[@wernerhahling916]

Absolutely brilliant video, explanations and problem solving techniques - my problem now is whether it'll be worth to get that "X431 pro 3s" and break-out connectors (they are NOT cheap) and the shop manual, or the circuit diagrams at least, to follow the same because MY 2004 RX8 has very much the same issues with DSC, TCS, Break lights mostly solid on (they do go off very occasionally) and my mechanic cannot even see an error code?!

[@_J4CKST3R_]

I’m a solid B tech but I’ve never done electrical diagnostics but I’ve already seen a couple of your videos and it looks fun, a little bit of a challenge, still learning how to read a wire diagram but it looks fun

[@lornaz1975]

I subscribed! You do such a good job of explaining and teaching that you are one of my main channels I watch. Thank you for your effort!

[@pacosoide]

Great show, very well explained. You are a very meticulous troubleshooter. Thanks for the work you do.

[@richmc8209]

It is possible to supply the abs module with powers and grounds and then probe the can outputs to see if there is a signal. It's even possible to connect a scan tool directly to the can high and low and directly communicate with it. A way to do this is to cut into the can lines at the back of the abs module to disconnect it from the rest of the network and then reconnect the wires afterwards.

[@reygarza7456]

Wow you impressed me, thanks I’ll be looking forward to learn more from you, we’re about to buy a 2011 RX 8 I’ll need all the help I can get with the Rotary Eng, Tu Eres La Mera Paipa de Diagnostics, I Toast a Agua de Mango in your Honor Señor, Gracias

[@Franz_giblet]

Another great video, your diagnostic skills are brilliant 💪🏻💪🏻

[@halfanhour2128]

I guessed it was the ABS module because my friends Toyota Camry had the same weird symptoms about 6 years ago. I googled her cars symptoms and found that others had the same problem that turned out to be the ABS. The sad part is that the module was not sold separately but part of the very expensive pump. I help her find a used pump on ebay and swapped the module that easily comes off with 4 screws.

Nice videos bro. Im a mechanic too for over 20 years. Rotary engines suck bad seals, drink oil like shlt

[@alexg9155]

Great video as always! I understand everything you say and show, but I still appreciate the explaining you do! Issue in this case is probably a cold solder joint where the connector containing the CAN wires is soldered on the board, probably that's why jt seems to work when it's really hot, solder probably melts a little bit and re-establishes connection. Muchas gracias para todo lo que haces :D

Can I get your suggestions on places to get electrical schematics. I’m legally blind I’m not totally blind. I’m a little hesitant to go spend a bunch of money on all data or something like that. If it’s not helpful for me. Love the videos love the information you have a gift for my friend keep up the good work.

[@fmbfla]

Awesome! Always start your diag with some insight, start your diag at a common sense location, Use the information you have and the test's that you do with your own input will (dont listen to someone looking over your shoulder) lead you to the next test or the fix and to the logical conclusion.

[@spelunkerd]

Well explained! I notice that in your CAN bus line there is a short repeating signal that has a higher voltage (on both arms) compared to the normal voltage for all the other signals. Your scope trigger was set on that higher voltage signal, at 5:06 of the video, at the right end of the screen. Is that normal?

[@Jpilgrim30]

Yes that is normal and I see that on about every car I’ve ever put a scope on the can bus. It’s called ringing. It’s an effect of inductance and capacitance in the circuit. He has his trigger towards the end of the screen but you’ll notice that little spike almost always occurs at the beginning of a group of signals and is caused by the controller that is transmitting initially driving the circuit high.

[@mardina1a]

İnspection was good but if you had a testing abs module it coud be easier to solve the problem.i'l allways check power lines before replacing the abs module thank ypu.

[@RetroCarGuy530]

After you removed the wire from the DLC that is for the dedicated communications bus for the SAS/DSC/ABS, the fact that scan tool stated it couldn't communicate with the ABS control module was used as proof the ABS control module was not communicating via the CAN bus. Maybe or maybe not.. You're assuming the scan tool software was written with logic to use both communication paths to the ABS module. Just because the dedicated communications path was removed doesn't necessarily mean the scan tool software is smart enough to figure that out and then to try communicating via the CAN bus instead. It might have that coded into the logic, but I don't believe there's no way to state 100 percent it can or will try using the CAN bus at that point. Your powers and grounds tests finding no faults along with the other modules/devices complaining about the ABS module strongly suggested that it was the ABS module at fault. Congrats on getting this figured out for that shop and the car owner!

[@vee985]

Eric Nice diag. Just wondering, was there a way just to reprogram the previous module to see if the problem disappears. Maybe a software glitch?

[@robbflynn4325]

All these computers and associated check engine codes on cars are an absolute nightmare when they start playing up as they usually do. I recall driving cars with manual chokes, and automatic transmissions were only usually in the more expensive vehicles, and air conditioning was winding down your window down, manually. Repairing and diagnosing vehicles back then was easy because they were so basic! I guess all the emissions rules and push for better fuel efficiency is the reason we are where we are now.

[@joeandgod1]

Is there any way of telling if a module needs to be replaced or just reprogrammed? Or do you got to just try to reprogram it and if it don't work, replace it.

[@stevetaylor2445]

Can hi and low does not refer to high speed and low speed,it refers to can high being voltage pulled higher from 2 1/2 volts up to 3 1/2 volts and can low being pulled lower from 2 1/2 volts down to 1 1/2 volts. It's is also easy to understand that they operate at the same speed because they mirror each other on the lab scope,if they were different speeds they would not mirror each other. The K line is usually operating at a different speed.

[@jum5238]

From your wiring diagram, I think that everything is basically spliced to one another, so just because you see "traffic" on the ABS CAN module lines, doesn't mean it's coming from the ABS module. You're probably seeing chatter from everything else on the lines. Remember, it's a CAN *BUS*. I agree that it was likely a bad solder joint, with intermittent connection.

[@jugubantan7740]

Eric you need to do a tutorial on to read a wiring diagram it would be easier learning from you

[@hectorgomez3580]

Hi my brother in law when i cheked his car same as this one you checked i told him it was the battery and he did not believe me he had his car parked for 2 months and finally he bought a battery it worked fine

[@gilron9585]

I am not electrician nor a mechanic and I understand this canbus error is a pain :) Car manufacturers should supply better tools to diagnose this like supplying the waveform between all modules without hooking pins to the car.. Throwing this to the electrician takes a lot of time and lot of trial and error :)

Can someone explain to me why exactly it is the abs control mod if he was able to communicate with the abs from the scan tool and get information back from the abs to the scan tool? I would think if the abs can communicate with the scan tool, then it should be able to communicate with the pcm. Now obviously I am wrong because it was the abs and not a wiring fault, but still is confusing I guess to me, so could someone explain?

I will have several On / Off cycles with any issues. then I will have an on / off cycle that the van doesn't like and the transmission will shift violently. turn the van off and restart it. the transmission will shift with out any issues.
