PARK SENSE/SERVICE SHIFTER CODES

[bfcollins]

The bad ground wire was from the harness that connects to the park sense module.

@bfcollins, can you post a PDF of your dealer invoice that shows the part number?

A bad ground. There is no part number, they fixed the ground.

My 2019 Dodge Ram Limited started malfunctioning, causing me to wreck when the shifter unexpectedly went into park while I was driving. The brakes locked up, making the truck slide, and by the time it switched back, I was already sliding off the road. (It had just rained and the roads were wet.)

I contacted the dealership about the issue four times prior to the accident. The body shop repaired the truck, but the shifter problem persists. The dealership claims the issue stemmed from the wreck, despite my explanation that it caused the wreck. They are currently attempting to fix it, but they still haven't identified the root cause.

I switched dealerships because the first one seemed incompetent. I'm hopeful that the current dealership's technicians will be able to solve the problem. Fingers crossed.

I had wondered if something like that could happen. There must be some kind of sensor, that tells if the truck is moving, to prevent it, but if that sensor is bad...... All vehicles seem to be going to electronic shifters. ( Except the HDs. They still use column shift.)

Ram gassers are 8 speeds, Cummins will get 8 speeds next year

Is that the reason for the column? Will they be dial? Some people don't like the dial, but I love it.

Column shift is due to the trans type and new 8 speeds will be electronic shift, I assume dial.

Anyone figure out how to fix this yourself? I figured it was a bad electrical connection. Mine is getting worse. It used to be every few weeks. Now it is every time I drive.

Not sure if this is the same issue you guys are having but I had a similar issue with my 2017 Cherokee. Prindle would randomly light up and say service shifter. I would have to pull over and put the car into park shut it off to cycle it and then turn it back on. That worked until it didn’t and I took it in to the dealer to fix it, I was still within my 36000 mile warranty so it was fixed with no charge. This was awhile go but if I remember correctly they replaced the transfer case wiring harness and I never had the issue again.

Hello all I’ve been dealing with this service shifter/Park sense sensor/Auto start disable! Light issue for months. I just recently discovered that ram Chrysler Jeep Dodge has issued a recall on the power control module (PCM). If you contact the dealer and give them your VIN they will conduct a software update on your vehicle. Please see the link provided Look for Vehicle Recalls | Official Mopar® Site

Hi guys. I am new to this. Have a 2019 1500 and I have the park sense issues myself. If I back up the brakes lock up and at random times the front sensors turn off. I literally just got the service shifter warning 10 minutes ago. I did notice that it doesn’t do it in the morning when it’s 90 degrees outside. But in the middle of the day when it’s blazing hot 115 degrees it does this

Same issues on my 2019 BigHorn- parksense unavailable has been occurring forever it feels like but service shifter more recent (last 2 years). I'm at my end, most likely trading in soon. The issue is definitely heat sensitive, as mine just went 8 months without dinging through Michigan fall, winter, and spring. Once summer weather rolled around it's been nonstop again (occured previous summer). Occasionally it will go into limp mode although rare. It did happen to us in the middle of bumper-to-bumper traffic in Atlanta and my wife was ready to give it away right then.
Today it dinged "service shifter" 20+ times as I slowly rolled through dealership lots looking at possible replacements. Being so annoying and consistent I swung through the RAM service and had them quickly connect a reader. All that showed up was "lost communication with parking assist control module." Could be a bad wire? ground? connection? harness? I have no idea where to even start and am not going to have them attempt random part replacements. I'm open for any ideas to narrow down cause and try to fix, but can't handle the errors anymore. Please Help!!

Did you ever find out what was causing it
