SYSTEM INSPECTION

●

When the Remote Keyless Entry System is malfunctioning, determine which part has caused the incident,
before carrying out the trouble diagnosis.

●

Using the following diagnosis flowchart, determine whether the electronic key or the vehicle component
(remote keyless entry receiver or BCM) has a malfunction and confirm the part to be checked.

Inspection with CONSULT-II

CONSULT–II Function

AIS001DW

CONSULT-II executes the following functions by combining data received and command transmitted via the
communication line from BCM. IVMS communication inspection, work support (only function setting of seats
and steering wheel), self-diagnosis, data monitor, and active test display.

Description

IVMS-
COMM CHECK

IVMS-
COMM DIAGNOSIS

Diagnosis of continuity in the communication line(s), and of the function of the 
IVMS-communication interface between the body control module and the 
local control units, accomplished by transmitting a signal from the body con-
trol module to the local control units.

WAKE-UP DIAGNOSIS

Diagnosis of the“ wake-up” function of local control units by having a techni-
cian input the switch data into the local control unit that is in the temporary 
“sleep” condition.

Each system 
inspection

Work support

Changes the setting for each function.

Self-diagnosis results

Carries out self-diagnosis.

Data monitor

Displays data relative to the body control module (BCM) input signals and var-
ious control related data for each system.

Active test

Turns on/off actuators, relay and according to the commands transmitted by 
the CONSULT-II unit.

BCM PART NUMBER

Displays BCM part No.
