PRECAUTION

  1. NOTICE FOR INITIALIZATION: NOTE: When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected. System Name See procedure Variable Gear Ratio Steering System Refer to «INITIALIZATION»(ref-386951-S21829001392011022400000) Theft Deterrent System Intuitive Parking Assist System
  2. PRECAUTIONS WHEN WORKING ON ELECTRIC STEERING LOCK After replacing the steering lock actuator, perform the code registration. Refer to «REGISTRATION»(ref-387084-S31120496972011022400000) . If the steering lock actuator is replaced, open and close the driver's door. The engine may not start until either operation is performed. HINT: Performing the above operation causes the steering lock actuator to memorize the correct steering lock bar position. If checking for push button start function DTCs or checking the DATA LIST with the power switch OFF, make sure that the driver's door is open. HINT: When the power switch is OFF, the main body ECU RH to which the Techstream is to be connected may not be working. Communication with the Techstream is impossible if the main body ECU RH is not working.
