ABS, TC, Service 4x4 lights with random ABS pump activation.

[SwankyTiger]

2021 Diesel Willys with 3600 miles.
Started with just the ABS pump randomly kicking on and now randomly kicks on and also pops the ABS, TC and Service 4X4 lights and pops up the Service ABS and Service Electronic Stability Control messages.
It happens randomly when braking, coasting, or accelerating.
It doesn't happen at highway speeds, just around town.
It doesn't matter if on flat ground, up hill, down hill, smooth roads, or rough roads.
The abs pump will activate without activating the lights occasionally and the lights will sometimes come on without the pump activating.
The lights will sometimes come on and then turn off after a few minutes(and keep coming on again at random) and sometimes they will stay on till I shut off the Jeep.

Its scheduled to go into the dealer tomorrow, so we will see.

I will forever blame the weird ones on the aux battery failing.

I will say that there was not a single fuse in the TIPM on either my 2020 Gladiator, nor my 2021 Power Wagon that was seated in the block.

I discovered that while looking for an accessory power point on the JT one day and seated them all. When the PW came in, that was the first thing I checked and it was the same way. I assume they are "built up" by robot.

The only time I have had the variety of codes you have there in my JT, Brer' Rat had dined on the wiring harness at the transfer case. Wiring insulation on those trucks (and i assume all the rest, because muh planets) is soybean based and attracts rodents like crazy.

Good luck.

already checked that and made sure everything was seated.

Dropped it off and they ran the codes which said it was a front left wheel speed sensor. So they are replacing it and we will see.

Super not impressed with this dealer so far.

They had to order the sensor as it wasnt in stock. Kept the truck all day before telling me this.

The never called me that the sensor was in. I ended up calling on the 21st and they said the part was in and would call me back that day on when I could bring the truck in.

They never called me back, and I ended up calling on the 25th and they said to bring the truck in so I dropped it off at 10am.

Still havent heard back about the truck yet.

I doubt it takes 2 days to change a wheel speed sensor.

ok they finally texted me and I picked up the truck and everything seems fine now

here are the notes.


CUSTOMER STATES THE ABS, TRAC, ESC, SVC 4 WHE EL DRIVE LIGHTS ALL CAME ON. PLS CHECK AND ADVISE

SCANNED AND FOUND CODES C0501-00, c0505-00, C 0031-1D, U0415-00 FOR LEFT FRONT WHEEL SPEED SENSOR

SENSOR HAD INTERNAL FAILURE THAT CAUSED ALL WARNING LIGHTS TO APPEAR. REMOVED AND REPLACED WHEEL SPEED SENSOR AND CLEARED CODES. RETESTED. OPERATING AS DESIGNED AT THIS TIME

still dont think it should take 2 days to change it but whatever.

Glad you got it fixed.

Wheel speed sensor including 2 instagram posts, 3 Facebook posts, hustling the parts girl, a cup of coffee and obligatory dump is a 30 minute job.

yea its the closest dealer at like 4 miles away and was able to schedule service sooner than the dealer that is 25 miles away but is the best locally and they were mid February for scheduling service back on the 1st week of January when I scheduled it.
