Circuit/System Description

WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The lane keep assist indicator is part of the S26 Hazard Warning Switch. The K9 Body Control Module controls the indicator using control circuit 3152 and the indicator receives a constant ground on ground circuit 1450. When the lane keep assist system is enabled, the K9 Body Control Module applies PWM voltage to circuit 3152, which will illuminate the indicator.
