1. CHECK COMBINATION SWITCH INPUT SIGNAL
With CONSULT-II
Select “BCM” on CONSULT-II. With “FLASHER” data monitor, make
sure “TURN SIGNAL R” and “TURN SIGNAL L” turns ON-OFF
linked with operation of lighting switch.
Without CONSULT-II
Refer to LT- 1 2 0 , "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 2.
NG >> Check combination switch (lighting switch). Refer to LT- 1 2 0 , "
Combination Switch Inspection" .
2. ACTIVE TEST
With CONSULT-II
1. Select “FLASHER” during active test. Refer to LT- 1 0 4 , "
ACTIVE
TEST" .
2. Make sure “FLASHER RIGHT” and “FLASHER LEFT” operate.
Without CONSULT-II
GO TO 3.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
NG >> GO TO 3.
3. CHECK TURN SIGNAL LAMPS CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and front combination lamp LH and RH connectors.
3. Check continuity between BCM harness connector M4 terminal 45 and front combination lamp LH harness connector E44 termi-
nal 4.
4. Check continuity between BCM harness connector M4 terminal 46 and front combination lamp RH harness connector E24 ter-
minal 4.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector. When lighting switch is
