ABS and BRAKE lights come on at different times. Sometimes while driving. Most of the time after short hops to different stores etc. If I turn the engine on and off 3 or 4 times the lights will stay off for a day or two. I've been told the ABS control module is bad. Can not afford to get it fixed at this time.
The ASB light stays on but have had no issues with braking.

Abs light come on & dealer said the the abs brake module is bad. It may stay off during cold mornings but always comes on when outside temp is warm. Brakes still operate well. I will have to pump brakes if car begins to skid. Would replace if I could find module cheap.

Brake warning light and ABS warning light come on at times, but there is no apparent loss of brake function. May be impacting ABS function only. Sometimes turning the engine off and back on will clear it, sometimes not.

I pulled the fuse to the ABS control module. This also disabled the cruise control, but now the truck is able to stop at slow speeds.
ABS light lights intermittently. Every so often there was a loud noise under the hood when brakes were applied.
