DTC C1905: Timeout Initialization Check of Rear Actuator: Description

Immediately after turning the power switch ON (READY), the rear 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 C1905. 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 rear active stabilizer control ECU when a malfunction in the front side occurs.
