2. CHECK GROUND CIRCUIT
Check continuity between time control unit harness connector M30
terminal 16 (B/R) and ground.
OK or NG
OK >> Power supply and ground circuit is OK.
NG >> Replace harness or connector.
Door Lock/Unlock Switch CheckEIS004DG
1. CHECK DOOR LOCK/UNLOCK SWITCH INPUT SIGNAL
Check voltage between time control unit harness connector M31 ter-
minal 20 (GY), 23 (PU) and ground.
OK or NG
OK >> Door lock/unlock switch is OK.
NG >> GO TO 2.
2. CHECK DOOR LOCK/UNLOCK SWITCH
1. Turn ignition switch OFF.
2. Disconnect power window main switch connector.
3. Check continuity between power window main switch.
OK or NG
OK >> GO TO 3.
NG >> Replace power window main switch.16 (B/R) – Ground : Continuity should exist.
