Example: When the HI BEAM switch is malfuncti oning, 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 malfunctioni ng, confirm that “TURN RH”, “HEAD LAMP 1” and “LIGHT
SW 1 ST” in System 5, to which HI BE AM switch belongs, turn ON-OFF normally.
Check results
Other switches in malfunctioning system operate normally.>>Replace light ing switch or wiper switch.
Other switches in malfunctioning syst em do not operate normally.>>GO TO 3.
3.CHECK HARNESS BETWEEN COMB INATION SWITCH AND BCM
1. Turn ignition switch OFF.
2. Disconnect BCM connector and combination switch connector.
3. Check for continuity between BCM harness connecto r (A) of the suspect system and the corresponding
combination switch connector (B).
4. Check for continuity between each of BCM harne ss 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.
