Check Encoder Circuit (Rear LH or RH)

POWER WINDOW SYSTEM


Check encoder Circuit (Rear LH or RH)

1.CHECK POWER WINDOW MOTOR (REAR LH OR RH) POWER SUPPLY
1. Turn ignition switch ON.
2. Check voltage between power window motor (rear LH or RH) connector and ground.










OK or NG
OK - GO TO 3.
NG - GO TO 2.
2.CHECK HARNESS CONTINUITY 1
1. Turn ignition switch OFF.
2. Disconnect power window sub-switch (rear LH or RH) and power window motor (rear LH or RH) connector.
3. Check continuity between power window sub-switch (rear LH or RH) connector and power window motor
(rear LH or RH) connector.










4. Check continuity between power window sub-switch (rear LH or
RH) connector and ground.





OK or NG
OK - Replace power window sub-switch (rear LH or RH).
NG - Repair or replace harness.
3.CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect power window motor (rear LH or RH) connector.
3. Check continuity between power window motor (rear LH or RH) connector and ground.










OK or NG
OK - GO TO 5.
NG - GO TO 4.
4.CHECK HARNESS CONTINUITY 2
1. Disconnect power window sub-switch (rear LH or RH) connector.
2. Check continuity between power window sub-switch (rear LH or RH) connector and power window motor
(rear LH or RH) connector.










OK or NG
OK - Replace power window sub-switch (rear LH or RH).
NG - Repair or replace harness.
5.CHECK ENCODER SIGNAL
1. Connect power window motor (rear LH or RH) connector.
2. Turn ignition switch ON.
3. Check signal between power window sub-switch (rear LH or RH) connector and ground with oscilloscope.















OK or NG
OK - Replace power window sub-switch (rear LH or RH).
NG - GO TO 6.
6.CHECK HARNESS CONTINUITY 3
1. Turn ignition switch OFF.
2. Disconnect power window sub-switch (rear LH or RH) and power window motor (rear LH or RH) connector.
3. Check continuity between power window sub-switch (rear LH or RH) connector and power window motor
(rear LH or RH) connector.










4. Check power window sub-switch (rear LH or RH) connector and ground.





OK or NG
OK - Replace power window motor (rear LH or RH).
NG - Repair or replace harness.
