DISPOSAL OF AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
Caution for Air Bag Module and Seat Belt Pre-tensionerINFOID:0000000003839142
Precaution for Work
 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 Disposing of Air Bag Module and Seat Belt Pre-tensioner. Refer to SR-25, "
Caution for 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 (SST: KV99106400).
 When deploying the air bag module and seat belt pre-tensioner, stand at least 5.0 m (16.4 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 irritates 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.
 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 after work is completed.
 Place the vehicle outdoors with an open space of at least 6.0 m (19.7 ft) on all sides when deploying air bag
module and seat belt pre-tensioner while mounted in vehicle.
 Use a volt meter to make sure the vehicle battery is fully charged.
 Never dispose of the air bag module and seat belt pre-tensioner that does not deploy.
CHECKING DEPLOYMENT TOOL
Connecting to Battery
CAUTION:
The battery must show voltage of 9.6 V or more.
Remove the battery from the vehicle and place it on dry wood blocks
approximately 5.0 m (16.4 ft) away from the vehicle.
 Wait 3 minutes after the vehicle battery is disconnected before pro-
ceeding.
 Connect red clip of deployment tool (A) to battery positive terminal
and black clip to negative terminal.
Check that the polarity is correct. The right side lamp in the
tool, marked “deployment tool power”, should illuminate with a
green light. If the right side lamp illuminates red, reverse the
connections to the battery.
Deployment Tool Check
Press the deployment tool switch (C) to the ON position. The left
side lamp in the tool, marked “air bag connector voltage” should illu-
minate (B). If it does not illuminate, replace the deployment tool (A).

< FUNCTION DIAGNOSIS >
EPS SYSTEM
 The valve driving voltage to control the power steering solenoid
valve varies according to the vehicle speed.
OPERATION PRINCIPLE
During Parking (When Turning The Steering Wheel To The Right.)
1. Power steering solenoid valve is closed while a vehicle is stopped.
2. Pinion “1R”, “2R” and “3R” are closed depending on steering torque of steering wheel.
3. Oil pressure “P” in the gear housing assembly is the sum of oil pressures occurred in “2R” and “3R”. This
results in a light steering force because of high pressure.
During High-speed Operation
1. Power steering solenoid valve is opened during high-speed operation.
2. Pinion “1R”, “2R” and “3R” are closed depending on steering torque of steering wheel.
3. Oil pressure “2R” does not occur because the power steering solenoid valve is on full throttle.
4. Oil pressure “P” in the gear housing assembly includes only oil pressure occurred in “3R” and results in a
heavy steering force.

ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Precaution for TCM
and CVT Assembly Replacement
INFOID:0000000003848916
CAUTION:
• Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
 When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.
EEPROM ERASING PATTERNS
METHOD FOR ERASING THE EEPROM IN THE TCM
1. Turn ignition switch ON.
2. Move selector lever to “R” position.
3. Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.
4. Press the brake pedal and turn the brake switch ON.
5. Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open
position. (This will set the closed throttle position signal to OFF and the wide open throttle position signal
to OFF.)
6. Perform “ERASE”.
7. Wait 3 seconds and then release the accelerator pedal.
8. Turn ignition switch OFF.
METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.
1. Erase the EEPROM in the TCM.
2. Move selector lever to “P” position.
3. Turn ignition switch ON.
CHECK METHOD
 Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
 Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds or
illuminates immediately.
CAUTION:
Perform in the “P” or “N” position.
Action for Non-standard
 Replace the CVT assembly.
 Replace the TCM.
CVT assembly TCM Erasing EEPROM in TCM Remarks
Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.
Replaced Not replaced RequiredRequired because data has been written in the EE-
PROM in the TCM and because the TCM cannot write
data from the ROM assembly in the transmission.

< PRECAUTION >[CVT: RE0F09B]
PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003897196
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000003849068
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MI to light up.
 Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt,
bent terminals, etc.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MI to light up due to a short circuit.
 Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precaution for TCM and CVT Assembly ReplacementINFOID:0000000003849069
CAUTION:
 Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
 When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.
