DESCRIPTION

DTC Detection Condition:

The active stabilizer converter supplies operating power to the rear active stabilizer control ECU from the rear active stabilizer control actuator. Also, when the battery (for active stabilizer) voltage is low, the active stabilizer converter charges it. If a problem occurs in the rear active stabilizer control ECU, rear active stabilizer control actuator, battery (for active stabilizer) and PIG power source circuit, DTCs C1913/12, C1915/22 and C1928/18 are stored.
