Combination Switch Inspection

EKS009LR

SYSTEM CHECK

Referring to table below, check to which system the malfunctioning switch belongs.

>> GO TO 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 carries out CAN communication.

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

Select "DATA MONITOR".

Select "START", and confirm that other switches in malfunction-
ing system operate normally.
Example: When 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

Operate combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When 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.
