Diagnosis Procedure

Detects condition of the driver side power window motor operation and transmits to power window main switch as the pulse signal.

1. CHECK ENCODER OPERATION 
   1. Turn ignition switch ON.
   2. Check signal between power window main switch harness connector and ground with oscilloscope.

      (+)		(-)	Signal (Reference value)
      Power window main switch
      Connector	Terminal
      D8	9	Ground	Refer to the following signal
      	13

   Is the inspection result normal?

   YES

   Replace power window main switch. Refer to POWER WINDOW MAIN SWITCH : Removal & Installation .

   NO

   GO TO 2.

2. CHECK ENCODER SIGNAL CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect power window main switch connector and driver side power window motor connector.
   3. Check continuity between power window main switch harness connector and driver side power window motor harness connector.
