Check Power Window Main Switch Power Supply Circuit

CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch ON.
2. Check voltage between power window main switch connector D6, D7 terminal 10, 19 and ground.
  10 (BR) - Ground : Battery voltage
  
  19 (W) - Ground : Battery voltage
OK or NG

OK : Power window main switch power supply and ground circuit are OK.

NG : GO TO 2.

CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect power window main switch connector.
3. Check continuity between power window main switch connector D7 terminal 17 and ground.
  17 (B) - Ground : Continuity should exist.

OK or NG

OK : GO TO 3.

NG : Repair or replace harness.
CHECK HARNESS CONTINUITY
1. Disconnect BCM connector.
2. Check continuity between BCM connector M4 terminal 53, 54 and power window main switch connector D6, D7 terminal 10, 19.
  53 (Y/B) - 10 (BR) : Continuity should exist.
  
  54 (W) - 19 (W) : Continuity should exist.
3. Check continuity between BCM connector M4 terminal 53, 54 and ground.
  53 (Y/B) - Ground : Continuity should not exist.
  
  54 (W) - Ground : Continuity should not exist. PIIA6280E
