Combination Switch InspectionNKS004YQ
1. SYSTEM CHECK
Referring to table below, check which system malfunctioning switch belongs to.
>> Check the system to which malfunctioning switch belongs, and GO TO 2.
2. SYSTEM CHECK
With CONSULT-III
1. Select "COMBI SW" of BCM data monitor item.
2. Confirm that other switches in malfunctioning system operate normally.
Example: When the HI BEAM switch is malfunctioning, confirm that “TURN RH”, “HEAD LAMP 1” and
“LIGHT SW 1 ST” in System 5, to which the HI BEAM switch belongs, turn ON-OFF normally.
Without CONSULT-III
Operating combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When the HI BEAM switch is malfunctioning, confirm that “TURN RH”, “HEAD LAMP 1” and “LIGHT
SW 1 ST” in System 5, to which HI BEAM switch belongs, turn ON-OFF normally.
Check results
Other switches in malfunctioning system operate normally.>>Replace lighting switch or wiper switch.
Other switches in malfunctioning system do not operate normally.>>GO TO 3.

3. HARNESS INSPECTION
1. Turn ignition switch OFF.
2. Disconnect BCM and combination switch connectors.
3. Check for continuity between BCM harness connector of the suspect system and the corresponding com-
bination switch harness connector.
4. Check for continuity between BCM harness connector in suspect malfunctioning system and ground.
OK or NG
OK >> GO TO 4.
NG >> Check harness between BCM and combination switch for open or short circuit.

4. BCM OUTPUT TERMINAL INSPECTION
1. Connect BCM and combination switch connectors.
2. Set wiper intermittent dial position 4.
3. Turn ignition switch ON.
4. Check BCM output terminal voltage waveform of suspect mal-
functioning system.
OK or NG
OK >> Open circuit in combination switch, GO TO 5.
NG >> Replace BCM. Refer to BCS-17, "
Removal and Installation of BCM" .
5. COMBINATION SWITCH INSPECTION
