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.
CHECK HARNESS BETWEEN COMBINATION SWITCH AND BCM
1.
Turn ignition switch OFF.
2.
Disconnect BCM connector and combination switch connector.
3.
Check for continuity between BCM harness connector (A) of the suspect system and the corresponding
combination switch connector (B).
4.
Check for continuity between each of BCM harness connector in suspect malfunctioning system and
ground.
OK or NG
OK
>>
Check BCM input/output signal of malfunctioning input/output.
• Input: GO TO 4.
• Output: GO TO 5.
NG
>> Repair harness or connector.
