EXTERIOR LAMP BATTERY SAVER CONTROL
When the lighting switch is in the 1ST or 2ND position (or if auto light system is activated), and ignition switch
is turned from ON or ACC to OFF, battery saver control function is activated.
Under this condition, illumination lamps remain illuminated for 5 minutes, then illumination lamps are turned
off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionAKS007EJ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2

Concept of Auto Active Test

IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.

If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

TROUBLE DIAGNOSIS
Revision: 2005 July 2005 FX
TROUBLE DIAGNOSISPFP:00004
Fail-Safe FunctionADS000S1

If any malfunction occurs in AWD electrical system, and control unit detects the malfunction, AWD warn-
ing lamp on combination meter turns ON to indicate system malfunction.

When AWD warning lamp is ON, vehicle changes to rear-wheel drive or shifting driving force-AWD (Front-
wheels still have some driving torque).
How to Perform Trouble DiagnosisADS000S2
BASIC CONCEPT

To perform trouble diagnosis, it is the most important to have understanding about vehicle systems (con-
trol and mechanism) thoroughly.

It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptoms by driving vehicle with
customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like "maybe the customer means that...," or
"maybe the customer mentions this symptom".

It is essential to check symptoms right from the beginning in
order to repair malfunctions completely.
For intermittent malfunctions, reproduce symptoms based on
interview with customer and past examples. Do not perform
inspection on ad hoc basis. Most intermittent malfunctions are
caused by poor contacts. In this case, it will be effective to shake
suspected harness or connector by hand. When repairing with-
out any symptom diagnosis, you cannot judge if malfunctions
have actually been eliminated.

After completing diagnosis, always erase diagnostic memory.
Refer to TF-23, "
How to Erase Self-Diagnostic Results" .

For intermittent malfunctions, move harness or harness connec-
tor by hand. Then check for poor contact or reproduced open circuit.

Self-DiagnosisAES000Z7
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds.
