Circuit Description

WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

The stop lamp switch signal circuit is a direct hardwire input to the engine control module (ECM) from the brake switch assembly. The ECM monitors the stop lamp switch signal circuit in order to detect when the brake pedal has been applied.
