ACTIVE STABILIZER SUSPENSION SYSTEM, Diagnostic DTC:C192D

DTC Code DTC Name
C192D Timeout Initialization Check of Front Actuator

DESCRIPTION

Immediately after turning the power switch on (READY), the front active stabilizer control ECU checks the condition of the active stabilizer suspension system. If there is a malfunction during the check, the initial check does not complete, resulting in the output of DTC C192D. Also, the initial check can determine if the rear active stabilizer control ECU is in the front or rear of the vehicle, and if the front active stabilizer control ECU is in the front or rear of the vehicle. This DTC is output by a normally recognized front active stabilizer control ECU when a malfunction in the rear side occurs.
