- PRECAUTIONS WHEN WORKING ON STEERING LOCK SYSTEM After replacing the steering lock actuator assembly, perform the code registration. Refer to «REGISTRATION»(ref-428886-S29159434012011101200000) . If checking for steering lock system DTCs 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 body ECU to which Techstream is to be connected may not be working. Communication with Techstream is impossible if the body ECU is not working. If the steering lock ECU 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 ECU to memorize the correct steering lock bar position.
