LIN Communication System

NETWORKING: LIN COMMUNICATION SYSTEM: PRECAUTION; 2013 MY Corolla [07/2012 -]

1. PRECAUTIONS WHEN USING TECHSTREAM

(a) When using the Techstream with the engine switch off to troubleshoot: Connect the Techstream to the vehicle, and turn the courtesy light switch on and off at 1.5-second intervals until communication between the Techstream and the vehicle begins.

(b) After all DTCs are cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).

2. PRECAUTIONS WHEN WORKING ON ELECTRIC STEERING LOCK

(a) If the steering lock ECU (steering lock actuator assembly) is replaced, open and close the driver door. The engine may not start until this is performed.

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