On-Board Diagnosis

On-board Diagnostic Function




^ Before operating troubleshooting, operate the procedure shown.

Output Device Operation Check




^ The keyless unit sends a signal to CPU and CPU activates the device every 3 seconds in the steps shown.

Failure Indication




^ The number of times CPU buzzer sounds indicates whether or not the keyless unit and CPU are communicating properly.

NOTE: If the buzzer sounds once, the keyless unit's digital circuit (keyless unit-CPU-door lock actuator) is operating normally. If the transmitter still does not operate when the digital circuit is normal, the trouble is in the high-frequency circuit (transmitter-antenna-keyless unit).
