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.
