This started happening on me. 2006 EXT. ABS light never comes on. Plus the rapid chiming you can get if you put the emergency brake on while driving. What's really fun is that just going down the road, the lights can kind of intermittently go on and off, along with the chiming
I've even had it happen just parked in the driveway. I made a video of that maybe I'll post it.
Lots of times though the stabiltrak and brake warning indicator, once they come on, will stay on. I pulled the brake fluid level sensor harness, no effect. Jumped it with a paperclip, no effect. I measure the voltage through the harness and it's 1.5 volts, doesn't sound right but I don't know what the proper voltage is, or if it's pulsed etc. Brakes work perfect, and fluid level spot on.
No ABS codes, and no check engine lights. In fact I cleared everything, and just putting the car into run without starting will trigger the 2 indicator lights and rapid chiming.
I'm about the change the ignition switch to rule that out. Anybody else with any thoughts have at it thanks. I played around with the parking brake switch near the lever but it seems ok. On the rare times the lights go out, I can pull up on the parking brake and the brake indicator light comes on and off correctly, with a little chiming. Also the brake lights come on correctly when the brake pedal is depressed, I checked those as well.
