After Recalibrating And Restting My Apps I Did Both.Now My Brake Light And Abs Light Stays On . I TOOK A DRIVE AND IT DROVE FINE AND EVERY THING WORKS .Can Anyone Shed Some Light On This?

 

Usually the culprit is the speed sensor on the top of the rear differential.

Less common is the sensors on the front wheels.

Turn the key from off to on 3 times, leaving it on the third time and check for codes in the odometer window.

I had the lights on after resetting my APPS, but that was probably due to the fact that I had the connector on the PCM unplugged while the key was on. The lights went off as soon as I started moving.

 

Ok I Checked Codes I Have 1687 1693 1694 1698 0236 0237 But Think I Got These Codes When I Accidently Started Up My Truck With The Comp Box Unplugged .and What Do You Have To Do To Reset These Codes?

 

Yup all 3 of those sensors are gone on my truck. Put the scan tool on it the other day at school and those 3 came up. I'm not really too worried about it because well, don't need ABS.
