Combination Switch Inspection

NKS002P4

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-II

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication. 

1.

Connect CONSULT-II, and select “COMB SW” on “SELECT
TEST ITEM” screen.

2.

Select “DATA MONITOR”.

3.

Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: When the auto light switch is malfunctioning, confirm
that “FRONT WIPER LOW” and “FRONT WIPER INT” in system
3, to which the auto light switch belongs, turn ON-OFF normally.

Without CONSULT-II

Operating combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When the auto light switch is malfunctioning, confirm that FRONT WIPER LOW and FRONT WIPER
INT in system 3, to which the auto light switch belongs, operate 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.

CHECK HARNESS

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector and combination switch connector.

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.
