Normal Operation
The speed control deactivator switch interrupts the power signal to the powertrain control module (PCM) through circuit 307 (BK/YE) when the brake pedal is applied firmly and passes the speed control deactivator switch trip point. This is a redundant signal to the PCM.
Possible Causes
- Fuse
- Circuit 307 (BK/YE) open or short to voltage
- Circuit 1140 (VT) open
- Speed control deactivator switch
- PCM
