Steering Column: Service Precautions

STEERING COLUMN: STEERING LOCK SYSTEM: PRECAUTION

1. PRECAUTIONS WHEN WORKING ON ELECTRIC STEERING LOCK

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

(b) 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.

(c) 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 junction block RH) may be in a sleep mode. If the main body ECU RH (cowl side junction block RH) is in this sleep mode, it will not be possible to communicate with the Techstream.
