Diagnosis Procedure

Detects condition of the passenger side power window motor operation and transmits to power window sub-switch as the pulse signal.

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

      (+)		(-)	Signal (Reference value)
      Power window sub-switch
      Connector	Terminal
      D38	12	Ground	Refer to the following signal

   Is the inspection result normal?

   YES

   Replace power window sub-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 sub-switch connector and passenger side power window motor connector.
   3. Check continuity between power window sub-switch harness connector and passenger side power window motor harness connector.
