2011 Lexus IS 250 Base, AWDFACTORY OEM SERVICE PROCEDURE

Steering Lock System: Precaution: Precaution

  1. PRECAUTIONS WHEN WORKING ON STEERING LOCK SYSTEM 
    1. After replacing the steering lock actuator assembly (steering lock ECU), perform the code registration.
    2. If the steering lock actuator assembly is replaced, open and close the driver's door. The engine may not start until either operation is performed.

      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 push button start function or 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 RH (cowl side J/B RH) may be in a sleep mode. If the main body ECU RH (cowl side J/B RH) is in this sleep mode, it will not be possible for the Techstream to communicate with it.
