Intermittent Stabilitrack Off message

[ukrkoz]

Hi all

Ever so often, Stabilitrack Off light started coming up.
It's just that message. No DTC codes. Just chime, message, blinks few times and disappears. It did it few weeks ago but went away. So it's something really intermittent.
No other messages. No, take it back - Parking assist off came on once.
I REALLY don't want to spend any more money on this vehicle, it's been money pit since spring.
Anything I should look at?

Wheel speed sensors first. You close to or have a Tech2? Could be as simple as disconnecting some connections and cleaning them with some contact cleaner and reassembling.

Easy can. Brake switch is also only few months old. Found one brake light was not working.
I also removed ELM BT dongle I had in OBD port. Every car I had that dongle in eventually started throwing ABS codes. I'll test drive it tomorrow.
MOF, I had front wheels off for balancing a week ago, could have dislodged something remounting them. F....s are heavy. I'll check it out tomorrow am, it's sleepy time here

My karma normally is - if I say, something was fixed, it normally comes back.
But, it's been over two weeks since my OP, so I'd likely safely say, I fixed it.
Not sure which one of the two did it but, here we go:
1. talked to buddy, who owned 4 Tahoe and has repair shop. He told me to check brake switch. Indeed, when I bought the truck, I replaced brake switch right away and that fixed THEN Stabilitrack message. So I checked brake lights and, apparently, pass side one was off. Otherwise, bulb worked and both filamnets were fine. MOF, both bulbs were replaced same time as brake switch. Anyhow. I simple swapped out bulbs side to side and they both work. Who knows.
2. most like cause. I was driving around with ELM BT dongle, to have Torque connected. Thing is, I had same dongle in two of cars I owned before and BOTH started throwing ABS codes after about a month of use. So I removed that dongle, same time I swapped light bulbs.

Just FYI.
