DIAGNOSTIC PROCEDURE 6
Inspecting SRS Malfunctioning Parts by Using “AIR BAG” Warning Lamp — Diagnosis Mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is detected in User mode.
1. Turn ignition switch ON.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat the steps 1 to 3 two times.
5. Turn ignition switch ON.
SRS is now in Diagnosis mode.
“AIR BAG” warning lamp operates in Diagnosis mode as follows:

REMOVAL
CAUTION:
Before servicing SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
1. Remove the driver air bag module. Refer to SRS-35, "
Removal and Installation" .
2. Remove horn switch connector.
3. Set the steering wheel in the neutral position.
4. Remove the steering wheel. Refer to PS-11, "
Removal and Installation" .
5. Remove the steering column covers. Refer to IP-16, "
(S) Steering Column Upper / Lower Cover" .
6. Remove the wiper and washer switch, lighting and turn signal switch from spiral cable.
CAUTION:
Do not disassemble spiral cable.
Do not apply lubricant to the spiral cable.

DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONERPFP:00014
Caution for Air Bag Module and Seat Belt Pre-TensionerBHS0004N
Before disposing of air bag module and seat belt pre-tensioner, or vehicles equipped with such systems,
deploy the systems. If such systems have already been deployed due to an accident, dispose of them as
indicated in SRS-48, "
DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER" .
When deploying the air bag module and seat belt pre-tensioner, always use the Special Service Tool;
Deployment tool (KV99106400).
When deploying the air bag module and seat belt pre-tensioner, stand at least 5 m (16 ft) away from the
deployment component.
When deploying air bag module and seat belt pre-tensioner, a fairly loud noise is made, followed by
smoke being released. The smoke is not poisonous, however, be careful not to inhale smoke since it irri-
tates the throat and can cause choking.
Always activate one air bag module at a time.
Due to heat, leave air bag module unattended for more than 30 minutes after deployment. Also leave seat
belt pre-tensioner unattended for more than 10 minutes after deployment.
Be sure to wear gloves when handling a deployed air bag module and seat belt pre-tensioner.
Never apply water to the deployed air bag module and seat belt pre-tensioner.
Wash your hands clean after finishing work.
Place the vehicle outdoors with an open space of at least 6 m (20 ft) on all sides when deploying air bag
module and seat belt pre-tensioner while mounted in vehicle.
Use a voltmeter to make sure the vehicle battery is fully charged.
Do not dispose the air bag module and seat belt pre-tensioner undeployed.
CHECKING DEPLOYMENT TOOL
Connecting to Battery
CAUTION:
The battery must show voltage of 9.6V or more.
Remove the battery from the vehicle and place it on dry wood blocks
approximately 5 m (16 ft) away from the vehicle.
Wait 3 minutes after the vehicle battery is disconnected before
proceeding.
Connect red clip of deployment tool to battery positive terminal
and black clip to negative terminal.
Make sure the polarity is correct. The right side lamp in the tool,
marked “deployment tool power”, should glow with a green
light. If the right side lamp glows red, reverse the connections
to the battery.
Deployment Tool Check
Press the deployment tool switch to the ON position. The left side
lamp in the tool, marked “air bag connector voltage” should illumi-
nate. If it does not illuminate, replace the tool.

Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
–When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
2. Sleep status
–When BCM is in sleep status, transistors of OUTPUT 1 stop the output, and BCM enters low power mode.
OUTPUT 2- 5 send out ON signal every 60 ms, and accept only input from lighting switch (except turn sig-
nal switch) system.
CAN Communication System DescriptionBKS001TH
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex 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
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CAUTION:
Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-II. Refer to
