Customer Safety Information
FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONERHINT: The xA is equipped with a Supplemental Restraint System (SRS) and seat belt pretensioner.
Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly deploy while servicing and cause a serious accident.
Furthermore, if a mistake is made when servicing the SRS, it is possible that the SRS will fail to operate when required. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully. Then follow the correct procedures described.
a. GENERAL NOTICE
1. Malfunction symptoms of the SRS are difficult to confirm so the diagnostic trouble codes become the most important source of information when troubleshooting. When troubleshooting the SRS, always check the diagnostic trouble codes before disconnecting the battery.
2. Work must be started at least 90 seconds after the ignition switch is turned to the "LOCK" position and the negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source. So, if work is started within 90 seconds after disconnecting the negative (-) terminal cable from the battery, the SRS may deploy).
When the negative (-) terminal cable is disconnected from the battery, clock and audio system memory is erased. Before starting work, make a record of the settings of each memory system. When work is finished, reset the clock and audio systems as before. Never use a back-up power source (battery or other) to avoid erasing system memory. The back-up power source may power the SRS and cause it to deploy.
3. Even in the case of a minor collision where the SRS does not deploy, the horn button assembly, instrument panel passenger airbag assembly and seat belt pretensioner should be inspected.
4. Never use the SRS related parts from another vehicle. When replacing the parts, replace them with new parts.
5. Before repairs, remove the airbag sensor if there is a possibility of shock during repairs.
6. Never disassemble and repair the center airbag sensor assembly, side airbag sensor assembly, horn button assembly, instrument panel passenger airbag assembly, front seat airbag assembly, curtain shield airbag assembly or seat belt pretensioner.
7. Replace the center airbag sensor assembly, side airbag sensor assembly, horn button assembly or instrument panel passenger airbag assembly, curtain shield airbag assembly if:
1. damage has occurred from being dropped, or
2. if there are cracks, dents or other defects in the case, bracket or connector.
8. Do not directly expose the airbag sensor assembly, side airbag sensor assembly, horn button assembly, instrument panel passenger airbag assembly or the seat belt pretensioner to hot air or flames.
9. Use a volt/ohmmeter with high impedance (10 kOhms/V minimum) for troubleshooting electrical circuits.
10. Information labels are attached to the SRS components. Follow the instructions on the notices.
11. After work on the SRS is completed, check the SRS warning light.
b. SPIRAL CABLE (in Combination Switch)
1. The steering wheel must be fitted correctly to the steering column with the spiral cable at the neutral position, otherwise cable disconnection and other troubles may occur.
c. HORN BUTTON ASSEMBLY (with Airbag)
1. When removing the horn button assembly or handling a new horn button, it should be placed with the top of the pad surface facing upward. Placing it with the pad surface facing downward may lead to a serious accident if the airbag deploys for under certain conditions. Also, do not place anything on top of the horn button.
2. Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
3. Grease should not be applied to the horn button assembly, and the pad should not be cleaned with any type of detergent.
4. Store the horn button assembly where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical noise.
5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (4 yellow pins). These connectors contain shorting springs. This feature reduces the possibility of the air bag or seat belt pretensioner deploying due to currents entering the squib wiring.
6. When disposing of the vehicle or the horn button assembly by itself, the airbag should be inflated using an SST before disposal. Perform the operation in a safe place away from electrical noise.
d. INSTRUMENT PANEL PASSENGER AIRBAG ASSEMBLY
1. Always place a removed or new instrument panel passenger airbag assembly with the airbag inflation direction facing upward. Placing the airbag assembly with the airbag inflation direction facing downward could cause a serious accident if the airbag deploys.
2. Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
3. Grease should not be applied to the instrument panel passenger airbag assembly and the airbag door should not be cleaned with detergents of any kind.
4. Store the airbag assembly where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical noise.
5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (4 yellow pins). These connectors contain shorting springs. This feature reduces the possibility of the airbag or seat belt pretensioner deploying due to currents entering the squib wiring.
6. When disposing of a vehicle or the airbag assembly unit by itself, the airbag should be deployed using SST before disposal. Activate in a safe place away from electrical noise.
e. FRONT SEAT AIRBAG ASSEMBLY
1. Always place a removed or new front seat airbag assembly with the airbag inflation direction facing upward. Placing the airbag assembly with the airbag inflation direction facing downward could cause a serious accident if the airbag deploys.
2. Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
3. Grease should not be applied to the front seat airbag assembly, and the airbag door should not be cleaned with detergents of any kind.
4. Store the airbag assembly where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical noise.
5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (4 yellow pins). These connectors contain shorting spring. This feature reduces the possibility of the airbag or seat belt pretensioner deploying due to currents entering the squib wiring.
6. When disposing of a vehicle or the airbag assembly unit by itself, the airbag should be deployed using SST before disposal.
Activate in a safe place away from electrical noise.
f. CURTAIN SHIELD AIRBAG ASSEMBLY
1. Always place the removed or new curtain shield airbag assy in a clear plastic bag, and keep it in a safe place.
NOTE: Protection bag is not re-useable.
CAUTION: Never disassemble the curtain shield airbag assembly.
2. Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
3. Grease should not be attached to the curtain shield airbag assy, and the surface should not be cleared with detergents of any kind.
4. Store the airbag assembly where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical noise.
5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (2 yellow pins). These connectors contain shorting springs. This feature reduces the possibility of the airbag or seat belt pretensioner deploying due to currents entering the squib wiring.
6. When disposing of a vehicle or the curtain shield airbag assembly by itself, the airbag should be deployed using SST before the disposal. Perform operation in a safe place away from electrical noise.
g. SEAT BELT PRETENSIONER
1. Never measure the resistance of the seat belt pretensioner (This may cause the seat belt pretensioner to activate, which is very dangerous).
2. Never disassemble the seat belt pretensioner.
3. Never install the seat belt pretensioner on another vehicle.
4. Store the seat belt pretensioner where the ambient temperature remains below 80 °C (176 °F) without high humidity and away from electrical noise.
5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (2 yellow pins). These connectors contain shorting springs. This feature reduces the possibility of the airbag or seat belt pretensioner deploying due to currents entering the squib wiring.
6. When disposing of a vehicle or the seat belt pretensioner unit by itself, the seat belt pretensioner should be activated before disposal. Activate operation in a safe place away from electrical noise.
7. The seat belt pretensioner is hot after being activation, so allow some time for it to cool down sufficiently before disposal. Never apply water to cool down the seat belt pretensioner.
8. Oil, water, and detergents should not come in contact with the front seat outer belt.
h. AIRBAG SENSOR ASSEMBLY
1. Never reuse an airbag sensor assembly that has been involved in a collision where the SRS has deployed.
2. The connectors to the airbag sensor assembly should be connected or disconnected with the sensor mounted on the floor. If the connectors are connected or disconnected while the airbag sensor assembly is not mounted to the floor, it could cause accidental deployment of the SRS.
3. Work must be started at least 90 seconds after the ignition switch is turned to the "LOCK" position and the negative (-) terminal cable is disconnected from the battery, even if only loosening the set bolts of the airbag sensor assembly.
i. WIRE HARNESS AND CONNECTOR
1. The SRS wire harness is integrated with the instrument panel wire harness assembly. All connectors in the system are a standard yellow color. If the SRS wire harness becomes disconnected or the connector becomes broken due to an accident, etc., repair or replace it.
