How to Proceed With Trouble Diagnosis

AKS00AL6

Confirm the symptom or customer complaint.

Understand operation description and function description. Refer to

LT-86, "System Description"

Perform the preliminary check. Refer to

LT-95, "Preliminary Check"

Check symptom and repair or replace the cause of malfunction. Refer to

LT-101, "Trouble Diagnosis Chart

by Symptom"

Does the auto light system operate normally? If YES: GO TO 6. If NO: GO TO 4.

INSPECTION END

Preliminary Check

CONSULT-II executes the following functions by combining data reception and command transmission via
the communication line from BCM. Work support, self-diagnosis, data monitor, and active test display.

CONSULT-II BASIC OPERATION

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.
