1.CHECK POWER WINDOW SUB-SWITCH OUTPUT SIGNAL

1. Turn ignition switch ON.
2. Power window lock switch OFF.
3. Check voltage between power window sub-switch harness connector and ground.

   (+) | (−) | Condition | Voltage (V) (Approx.)
   Power window sub-switch
   Connector | Terminal
   D38 | 15 | Ground | Power window sub-switch | UP | Battery voltage
   Other than above | 0
   16 | DOWN | Battery voltage
   Other than above | 0

Is the inspection result normal?
YES>>Power window sub-switch function is OK.
NO>>GO TO 2.
