diate connector C-17 and junction block connector 
C-214, and repair if necessary.

• Check the input and output lines for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Repair the wiring harness.

Step 6. Connector check: E-15 front door lock 
actuator (RH) connector
