Circuit Description

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The cruise control set/coast switch is an input to the powertrain control module (PCM). This input allows the PCM to control and hold a requested speed. The cruise control set/coast switch sends a ignition positive voltage signal to the PCM when the momentary switch is applied. This DTC sets if the PCM senses a voltage on the set/coast switch signal circuit when the voltage is not expected.
