Intermittent Warning lights

[eroemer]

The ABS and Service 4WD and ESP/BAS and Tire Pressure and Traction Control instrument panel lights all come on, the chime plays, and then the lights all go off again right away. Lights are only on for 1-2 seconds.

Is this likely an actual issue with one of the systems indicated, or more likely an issue with the instrument panel warning system?

It does this even in Park, not moving. No difference if it is in 2WD or 4WD at the time.

I had this very same issue. Turned out to be the parking assist module. I would have never guessed that but when the dealer diagnosed it, that was the culprit .

Thanks! Will check that out.

Was your issue intermittent? The lights have not been coming on at all now the last few of times I’ve driven it. Issue started suddenly near the end if a long (10 hr) trip. Now it seems to have stopped.

How is your battery, terminals and ground connection ?
Funky things happen if any of the above are not in perfect shape. Also, have you checked for codes ?

Would it show a code if Check Engine light isn’t one of the lights lighting up?

Turns out it is the ABS speed sensor on the left rear wheel. Bought a new sensor at auto parts store, but now I have a new problem—the plastic shaft of the old sensor is broken off in the wheel.

Any ideas on how to remove the broken section?
