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.

Tip:

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.

DTC Code DTC Detection Condition Trouble Area
B2285 The steering lock position signal information from the cable and the steering lock position signal information from the LIN communication line are inconsistent.

  • AM2 fuse

  • Steering lock actuator assembly (steering lock ECU)

  • Power management control ECU

INSPECTION PROCEDURE

Note:

  • When using the intelligent tester with the engine switch off to troubleshoot: Connect the intelligent tester to the vehicle and turn a courtesy light switch on and off at 1.5 second intervals until communication between the intelligent tester and vehicle begins.

  • Before performing the inspection, check that there are no problems related to the CAN communication system and LIN communication system.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  • After replacing the steering lock actuator assembly (steering lock ECU), perform key ID code registration. Refer to the Service Bulletin for the registration procedure.
