Hi,

A couple of weeks ago, my BAS/ESP light came on. I tried the steering wheel calibration but the light would not go away. Over the past weekend, I started to realize that when I accelerate moderately hard, I feel the back brakes pulsating, If I let off or go full throttle, it goes away.I finally got my S20 key for my snap on code reader and plugged it in. I received the following codes.

1000 - CAB INTERNAL FAILURE
1200 - BRAKE LAMP SWITCH CKT
1022 - NO CAN COMMUNICATIONS WITH PCM
1025 - CAN SIGNAL
1131 - PCM NOT IDENTIFIED OR INCORRECT
1140 - STEERING ANGLE SENSOR CKT


Before this all started, I went for a day trip (probably about 120 miles total) and the car ran fine. I searched online and could not find a similar problem that had a solution. I read that the brake switch and steering angle sensor are common faults, but I find it kind of odd that all of the other codes would show up if it was just one of these two (or even both). Any help would be appreciated

Sorry if I am not following any rules correctly as this is my first post

Thanks!
