B2193, P1612 CHAIN OF ECM-IMMU
DescriptionINFOID:0000000001404183
BCM performs the ID verification with ECM that allows the engine to start. BCM starts the communication with
ECM if ignition switch is turned ON and starts the engine if the ID is OK. ECM prevents the engine from start-
ing if the ID is not registered.

BCM (BODY CONTROL MODULE)
REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal.
When a rear wiper auto stop signal is in the condition listed below, BCM stops power supply to rear wiper after
rear wiper is activated for five seconds.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

SRS AIR BAG SYSTEM
Front Passenger Air Bag Module
INFOID:0000000001396422
The front passenger air bag module is single stage and located
behind the instrument panel assembly (mounted to the steering
member). It operates with the SRS system in a frontal collision
exceeding a specified level.
Passenger Air Bag Deactivation SwitchINFOID:0000000001404302
The passenger air bag deactivation switch is located on the RH side
of the instrument panel. The switch can be operated with the ignition
key (models without Intelligent Key) or mechanical key (models with
Intelligent Key). When the switch is turned to th ON positition, the
passenger air bag is enabled and could inflate in a frontal collision.
When the switch is turned to the OFF position, the passenger air bag
is disabled and will not inflate in a frontal collision. After any SRS
repair, make sure the passenger air bag deactivation switch is in the
same position as when the vehicle arrived for service.
NOTE:
In case of customer concern, CONSULT-III can be used to confirm
the passenger air bag status (readiness).
Passenger Air Bag Deactivation Switch Status
Front Side Air BagINFOID:0000000001396351
Front side air bag modules are built into the front seatback assem-
blies. Vehicles with side air bags are equipped with labels as shown.
Side Curtain Air BagINFOID:0000000001396352
Side curtain air bag modules are located above the vehicle headlining.

Trouble Diagnosis IntroductionINFOID:0000000001396360
CAUTION:
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
nectors.
 Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace it
with a new one.
 Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-III.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-III are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
