Driver Side

DRIVER SIDE : Description 

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

DRIVER SIDE : Component Function Check 

1. CHECK ENCODER

   Check driver side door glass perform AUTO open/close operation normally by power window main switch.

   Is the inspection result normal? 

   YES: Encoder is OK.

   NO: Refer to "DRIVER SIDE : DIAGNOSIS PROCEDURE" below.

DRIVER SIDE : Diagnosis Procedure 

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