C0691 CHEVROLET Description

Battery voltage for the strut actuators is supplied to the Electronic Suspension Control (ESC) module through the damper drive relay circuit. The ESC module energizes the damper relay by opening and closing an internal ground for the damping relay coil control circuit. The ESC module monitors the damper drive relay circuit and each strut actuator high-side and low-side drive circuits for fault conditions.
