Code C1532 Scion Description

The Power Steering ECU monitors itself for proper operation. The Power Steering ECU sets the Diagnostic Trouble Code (DTC) when it detects an internal malfunction. If the Power Steering ECU Assembly stores this DTC, it will shut off the motor relay circuit (built into the Power Steering ECU Assembly) and stop power assist. However, power assist continues if this DTC is output.
