Dodge Charger: No Tail Lights & ABS / Trac Lights On

[@SouthMainAuto]

*UPDATE:* Customer returned later for the repairs. The right rear axle was replaced along with a new pigtail and light. He also had me install 4 new TPMS sensors to clone his summer wheels. All the lights are off (and on 😉) and everyone is happy. -Eric O.

[@richardthomas1743]

Oh my , so they are keeping it. The car still could benefit from fluid film , I know that it is getting crusty but the undercoat would still help to slow down the progression of the total disintegration of the underside LOL

[@cgmoog]

No preventative left axle?

[@siduramaxde]

shame on him for not doing the left axle while the diff was out...He'll be back! and job security for SMA

Indeed, not only yours:) it turned just better when it even was OK:)

[@SimiNelsonFamily]

Eric, hands down the best. He always teaches us how to diagnose and repair, and approaches it with honesty and sincerity. He finds the problem instead of guessing and throwing parts at the issue.

[@tyg9998]

could you reply and tell me when he starts talking about diagnose the vehicle at??

[@SimiNelsonFamily]

@@tyg9998, Eric’s diagnosis started with a scan of the systems, leading to the Body Control Module codes, followed by his research of the wiring diagram to understand how the BCM controls the lighting on the left rear and center lights. They led him to the first light in the circuit, which turned out to be the problem. A very methodical approach to discovering the problem. Eric’s videos routinely highlight his methodical approach to diagnosing issues, including extensive testing of components. Many other mechanics would venture a guess and replace parts until the problem goes away.

[@frizzlefry1921]

And just as important shows when he screws up. Nobody’s perfect regardless of what’s on social media it takes maturity to admit you made a mistake and fix it. Most people these days it’s just one denial after the next.

[@jimvanderveldt4883]

He definitely uses a smart methodical approach… not a try-agnostics parts changer. I learn something new with each video.

There is a permanent fix for this issue but I don't know what it costs to have the proper coating applied to this unit and wiring. (As a former fire alarm technician, I've seen plenty of ground fault troubles pop up on panels after a rain(s) as I currently witness where I live. Didn't see this fault on a new install at a gas station/market with underground wiring thanks to this wire.)

[@RenoBusdriver]

My grandfather was a mechanic worked for the City of Reno, NV. Self taught man with no high school or college education.

Rust belt is probably half the battle tbh. 20 pound sledge hammers, acetylene torch, "Big nasty" 1/2 impact and can of PB blaster is a necessity up here in Northern states!

Sometimes what I get most out of one of your videos is a heartfelt relief that I 1) don't live in the rust belt and 2) don't have a car with access problems like that. My anxiety level was rising just watching it. I'll watch the video where you do the repairs but I'm going to cover my eyes when you get to those two evil bolts.

[@donquijote6030]

Eric O. has to be the best mechanic on the YT. No offense, of course, to the many other mechanics that watch his videos. Your prowess in troubleshooting is really impressive.

[@TarZan49]

Thank you for the great content. I just drive cars...I never knew how complex they are until SMA.

[@LadyAnuB]

There's a video he did where he was working on a 1941 model and while it is less complex electrically/electronically, it has a bunch of lubrication points on it. So you exchange code reader/setter for grease gun.

[@boatingcharlie1]

Nice job! I wish all mechanics had the logic thinking to track down the real problem. So many people just throw parts at them and have no clue.

[@Fix_It_Again_Tony]

I like how they have the model name on the brake caliper. Must make assembly easy. Why not use a small wire brush on the threads of that axle to remove some of the rust before trying to take the nut off? I'm sure it still wont spin right off, but I've found it usually takes some of the fight out of rusted fasteners. Then again when I work on cars I save money I don't make money, so if it takes a bit longer its usually not a big deal.

[@300DBenz]

I have a wire wheel on a die grinder for doing exactly that. It also helps with tie rod adjuster nuts, swaybar endlinks, exhaust bolts, and cleaning off wheel hubs.

[@osrr6422]

@@300DBenz Little bit of lubrication of some sort (WD40, "Penetrating" oil, used motor oil, etc) helps even more when they're rusted.

[@garykirk1968]

Could just use a Milwaukee and zip it right off..

[@lvsqcsl]

None of that had ANYTHING to do with luck......That was your experience telling you where to go, Eric. Luck is when you fire the parts cannon and it fixes the issue. I recently had body work done on my Grand Marquis and the rear air suspension was inoperable when I got the car back. The body shop had the left front fender off the car and I suspected they had to unplug the air compressor located under the air cleaner. I checked the compressor and no power. I got a wiring diagram and those yaahoos forgot to plug the harness back in. It is because of you that I knew how to do that, Eric. Great video!

Retired GM tech, nice job. I believe I also ran into the remove the axle problem. I torn the whole suspension loose and then dropped the differential before I got it out. What a great design. Yes I was getting into a lot of resistance wiring problems. Seems the new computers feeding power to these circuit monitor the current draw very close and shut the circuit off if it is not right. Great Job, I live in Okla. still got a lot of rusty wiring. The first Camero I ran into that told me on the dash which bulb was out??? how did it do that, smart circuits.. Don

[@LadyAnuB]

I was a fire alarm tech and system wiring monitoring has been done for likely 50+ years in this industry. Moving on to cars, you can take modern electronics and easily monitor a whole boat load of stuff as you've seen. (Fire alarm system stuff is similar given the right panel and field devices.)

[@guyconnell2250]

I'm only 3 1/2 minutes in. Hopefully the new Dodges don't just turn off the circuit after x number of tries like the trailer brake circuit on the 2006 Dodge Ram. In that event you have to have the TIPPM reflashed to turn the circuit back on, and you can only have it refreshed five times. Brilliant! I couldn't think of anything better. Except maybe a fuse?

[@jayjaynella4539]

Somewhere in the millions of pages of documents delivered to each car company, issued by the bureaucraps in Washington who all hate automobiles and any form of personal transportation, is a regulation that requires what you just described above.

Great stuff as always. I always take the speed sensor out to check for the broken/missing magnet strip through the hole. 9/10 times they come right out on those (in PA, almost as bad rust wise). Also, blowing the knuckle out only takes about 10 mins and the axle slides right out. No reason to take exhaust/diff off. I have had several of those race track tail lights fill up with water and throw the same codes. good job using your 6th sense and going straight for the marker lol.

Shift interlock and most of the interior accessories wouldn't work on a Rav4, and immediately I thought "ignition switch", remembering back to you figuring that out with a (I think) Dodge Ram or F150, can't remember which truck it was. Plugged in the scantool and *boom* ignition switch stayed off unless you shook the steering column around.

There are plenty of good car washes here in NY (there's one literally right next to Eric's shop) but the problem is getting your car washed while it's below 32F leads to your windows/locks/etc all freezing up overnight.

[@richardirish2153]

@@chrisfreemesser5707 the automatic ones I have near me blow high powered jets of hot air when it’s done washing the car and that helps prevent the freezing.

I think someone could make a lot of money with the kind of wash we have in the Midwest! We have Mike’s Carwash and crew carwash here in Ohio and Indiana. I’m not sure if they are anywhere else? Not perfect but pretty darn good if you live in the salt belt!
