Circuit Description

WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The TCC/Stop lamp switch indicates the brake pedal status. The normally closed TCC/Stop lamp switch supplies a B+ signal to the powertrain control module (PCM). The signal voltage circuit opens when the brake pedal is applied.

If the PCM detects an open TCC/Stop lamp switch circuit during accelerations, then DTC P0719 sets. DTC P0719 is a type C DTC.
