Steering Lock System -- Precaution



1.PRECAUTIONS WHEN WORKING ON STEERING LOCK SYSTEM

  1. After replacing the steering lock actuator assembly (steering lock ECU), perform the key ID code registration.

  2. If the steering lock actuator assembly is replaced, open and close the driver's door. The engine may not start until the driver's door is opened or closed.

    HINT:
    Opening and closing the driver's door causes the steering lock actuator assembly (steering lock ECU) to memorize the correct steering lock bar position.

  3. If checking for DTCs of the smart key system function or if checking the Data List with the engine switch off, make sure that the driver's door is open.

    HINT:
    When the engine switch is off, the main body ECU may be in a sleep mode. If the main body ECU is in this sleep mode, it will not be possible for the Techstream to communicate with it. Opening and closing the driver's door will cause the ECU to exit the sleep mode.

2.PRECAUTIONS FOR STEERING LOCK ACTUATOR
NOTICE:
If the steering lock actuator (steering lock ECU) is replaced, open and close the driver side door with the engine switch off and the shift lever in neutral to record the current steering lock position into the steering lock ECU. If this is not performed, the engine may not start.
