All of them.

[@adamtrombino106]

The circuit wasn't even on the TIPM...I was big time confused at the other shop's diagnosis. But I figured it was a poor gnd. Chrysler is mighty stingy about adding redundant gnds. That being said, usually other problems with higher current draws show up 1st. SO this was a good case study. I dunno who builds these harnesses. My own 09 Challenger had an exterior lighting problem since day 1 ( headlights- std bulbs not HID) would pulse and you could hear the alt cycling at idle. I had it at the dealer 3 times. They replaced the battery, the alt, and the TIPM, same result. Luckily it didn't cost me anything. I grabbed a wiring diagram and found the gnd for all of that was loose in the crimp. I'm not a big solder guy, but that time I did. N/P since.

I have seen the same response. You would think that Chrysler would have learned that a " Totally Integrated Power Module" is not such a good idea by now, wouldn't you? As far as bad grounds go, I am 78 years old, and I learned about a bad ground being the very first thing to look for when I was about 12 years old, and that was back before solid state devices were used on cars.

Replaced O2 sensor multiple times, replaced PCM… every “solution” lead me down the wrong path & further away from this simple yet logical solution. My car is now code free, my left turn signal now shines brighter than the sun, & the performance has improved significantly. Thank you so much!!!!!!

[@StevenDaugherty-uo5cs]

It is sad that so many technicians at so many shops do not know how to do simple troubleshooting and diagnosis especially where wiring and electrical issues are concerned. My personal opinion is they rely too much on computers to tell them what's wrong and have never learned the basics of old school style troubleshooting. Dealerships are notorious for simply firing the parts cannon because they have parts on hand. This customer probably saved a bunch of money coming to you, even with the cost of the long drive. Great job as usual.

[@2nickles647]

Disagree calling Dealership notorious. Many Shops do this. And quit calling auto mechanic "Technician". It's an over used term. Just because you use a scanner does not make you a Technician. You might as well call the auto parts "technician" also. People come into parts stores. I want you to diagnose my car, it has a check engine light 🚨. Presto, spits out the codes on paper, gives them the codes and a solution to the repairs.😅😅 I laugh at this approach. I asked who made the decisions how to fix the problems.? I was told a "Team of professional Technician" developed the software and it's protected. 😅😅😅😅 One day I saw a report, to fix the problem, the report read, "De-ice the intake system", this was in the middle of summer, temp is 110 degs outside. I laughed so hard. How stupid must the so called professional Technician be or how stupid are people to believe this nonsense. I do agree with you 100% , they rely on a scanner codes to tell them what's wrong. There is no common sense. I've been following Ivan and Eric O all of the time to help me troubleshoot. Powers and grounds. They cannot beat that into my thick head. I even bought a 2 channel scope because of Ivan and Eric O. Well. Enough of my rant. Cheers

[@hddm3]

It's marvelous to see these videos where you're able to diagnose what was initially sold as a very expensive repair but turns out to be a simple, no parts required fix. The person who made the incorrect diagnosis would have gone on to perform the "repair" and of course the problem would have remained. Then what? The nightmare of having to shop your car around to find a competent mechanic is very real as well as the issue of payment for an incorrect diagnosis. In the meantime, your car is possibly out of service and you'd be mired in small claims court, because there's no way you should have to pay for incompetent repair work, most especially at 150 bucks per hour. It is unfortunate that there are so few Ivans in the repair world; worse that it actually makes Financial sense to seek him out despite the cost of shipping and inconvenience.

22:20 What causes corrosion there? Maybe gasses released by the battery causing it since the batter is so close to that ground point. All the differing metals that are exposed combined with the battery off gasses.

[@johnmccallum8512]

Yes a squirt of fluid film when new would have stoped that.

[@beauhatman4395]

I agree, 100%. Dissimilar metals corrosion plus the outgassing of the batt. Biggest fail is leaving everything exposed to atmosphere FROM THE FACTORY!!! A little spritz, of just about anything , would've prevented this from happening for a long time. Even covering it with oil or a little high temp grease (if you're REALLY on a tight budget). Inexcusable.

[@DaveReynolds-y3v]

I would guess it is because you have exposed wiring. This is especially the case anywhere outside the passenger compartment (Though not a good idea inside the passenger compartment either). When the atmosphere reaches the dew point those water molecules can easily carry contaminants.

[@JorgeFernandez-uc9qb]

There are two main problems there. One, the connection is just a crimp with no solder or heat shrink over it. Two, the connection is near the battery. The battery fumes will start to corrode the wires over time, especially since they are near the grill with all the moisture of driving when it is raining and such. My jeep used to have a wiring connector under the battery that disintegrated because of all the fumes and such. Great Job Ivan!

[@streetfighter.youtube]

[@ColeTanner88]

So they're using a bias voltage for module diagnostics to set circuit high codes. There's a high ohm resistor in the module, along with a voltage sensing circuit. When the heater driver is off, and the circuit/component are in tact, the module wants to see 0v. If there's an open in the circuit, be it, an open in the heater element, open in one of the wires or bad connection, that bias voltage isn't able to be pulled down. Great diag, Ivan.

[@chrisbentleywalkingandrambling]

I find it amazing that garages would rather fire a parts cannon than actually diagnose the issue and sort it out the first time. Is it just a case that people fire the cannon in the hope they get it right and then can hike up the bill, or is it just a fire and hope?

Hey Ivan or anyone else reading, if you're really serious about sealing off wires that have been probed give 3M 5200 marine sealant a shot. It comes in a toothpaste / RTV style tube and is so good it will immediately clog the spout after the first use. but all you have to do is poke a pin hole hole in the tube, squeeze an ant sized blob out for your wire and the tube will seal itself. Need more? poke another hole.

[@MikeF421]

Good job, only thing I don't agree with is the "small hole isn't going to hurt anything and it's not going to get the green crusty" right before fixing green crusty a foot away from your piercing probe. Always seal a pierced hole.

Excellent video as usual. From repeated experience, most employers have an invisible dart board with parts pictures; after running out of darts, they call the educated tech to bail them out of dancing backwards into a corner with the customers credit card, then they lie to the educated tech about what parts pictures the darts landed on and were replaced on the vehicle with the cheapest aftermarket parts they found. To add insult to injury they create a chaotic environment including loud annoying music playing through the shop. After the educated tech figures out the problem the shop owner resents having to pay him and asks all kinds of stupid questions, and then charges the customer for all the unneeded parts.

My Weller 921ZX soldering station will go to 850 degrees F but it is only 90 watts. Needs more power for a larger thermal mass. Find some older Kester or Ersin rosin core solder Not lead free!

It's caused by a bad ground reference to the battery from the factory. Where they mount the lug to the frame is not referencing the battery due to paint, e-coat ect. Once reconnecting the wires, make sure the paint is scraped. Clean and meter the resistance from that grounding point to the battery. If resistance is still high and unacceptable, start cleaning grounds back to the negative terminal of the battery.

[@Sandmansa]

Nice work Ivan. I can't tell you how many times I had those Jeeps come in with dim or non functioning lights. Always that same ground point. I didn't know the O2 sensors connect there too. Good to know. Also, Ivan. A nice little tip for when soldering on crimp connectors. It's best to tin the wires first. But if that's not an option, heat the area where you want the solder to end up at. Molten solder likes to flow towards the heat source.

[@JOHNSUE28]

[@greghanlon2235]

Nice one Ivan. Neglected orphan of diagnosing auto electronic issues... The Ground Side.

[@calholli]

The only bad thing about soldering the eyelets like this is that it makes a harsh break point in the wire. So you really have to make sure that the wires are tied down and not able to flop around. So there's always a trade off.......... It's just like knife steel: you can trade toughness for hardness, but you can't have both. But this repair should be great for the life of the car now.

[@edwardromana]

I have had the same experience. Soldered terminals will last a long time only if the wire does bend near the terminal itself. Terminals with a stain relief clamp are better. The wire following the solder terminal has to be well secured.

[@calholli]

@@edwardromana Yep.. When it's multiple wires like this, it's usually fine if you tape it all up well; because all the wires reinforce each other and won't bend. But I agree-- a little tie down near the connection is best.

I do not know what they are used for (terminating to some battery connections ? ) the terminals that are copper & enclosed at the eyelet is what I would use then you could place all the wires (all twisted together) soldered all of them in one large twist place a copper terminal & crimp as well some good telecommunications heat shrink that should give a complete seal & connection which I believe give a single eyelet to connect to the body (less chance of fatigue point at the nut & stud on the body.)

But this is another example of "wiring, not parts". You and Eric O. seem to get a lot of that.

Proved your point again bro...a good diag saves time and money of customers question is if the customers agree with it😮...great job always learn from your work and follow your footsteps in diags and believe me it saves me lot a trouble and time..same kinda issue resolved yesterday on a toyota verso etc(electronic throttle control system) malfunction a code p1725 with no definition and found one bad wire at the neck of pcm connector thx to your methods done it in a magical time NPR fix 😂

A Stellantis product with a BAD GROUND? NO WAY! 😉 Nice one, Ivan.

What’s scary is that the public is not pushing back against the seriously OUTDATED smog inspection. (That’s the only reason the money light is of concern to them.). We finally got rid of that scam here in one southern state.

I do not recommend piercing any pcm controlled circuits especially outside the vehicle as it will allow for corrosion/resistance. Disconnect C2 from pcm and 02 sensor, turn ignition on and test heater circuit for voltage (short to power) if not done first and there is v your continuity test is inaccurate, test ground. When performing continuity tests the circuit should be isolated . Manufacturers usually never list broken wires as possible causes as circuit testing is always part of they diagnostic chart. Using a scan tool to increase and decrease duty cycle while using a test light at the 02 sensor connector after will confirm pcm heater circuit pwm operation.

At 6:49 are those cherished head gaskets up on the wall? And an exhaust gasket?

Get an old giant weller pistol for the big stuff. That little solder pen just isnt hot enough to penetrate those big terminals. Maybe it works in the warm weather ok, but by you when its 5 degrees out, you will love the bigger Weller...

Ground connections like that will keep you in business for life. Off topic... Are there any two-wheel trips in the near future?

Thanks for the video Ivan.

The other thing you have going on with the grounds is electrolysis and/or galvanic corrosion due to the pure copper wires coming into contact with the zinc or tin plated eye connector. Introduce some moisture and a perfect storm of corrosion will occur. Since this seems to be a constant problem with jeeps and grounds, I'd make an educated guess that ganging the grounds to one large eyelet is probably allowing enough moisture to gather inside the crimp to cause the corrosive action.

I love how you overkill your repairs. I do the same thing.

Nice job Ivan, saved the customer a lot of money.
