DESCRIPTION
The power management control ECU and steering lock actuator (steering lock ECU) are connected by a cable and the LIN communication line. This DTC is stored when the steering lock position signal information from the cable and the steering lock position signal information from the LIN communication line are inconsistent.
HINT:
When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode is reset to on (IG). When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
