Inspection Procedure

1. Check that the manual door lock and unlock function operates normally.

   OK: Manual door lock and unlock function operates normally. 

NG :  GO TO POWER DOOR LOCK CONTROL SYSTEM 

OK : Go to next step 

1. Select the ACTIVE TEST, use the Techstream to generate a control command, and then check that the oscillator operates.

   Certification ECU:
