Technician Safety Information

NOTE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary instructions and the procedure and precautions for the applicable model year.

Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started after 90 seconds from the time the Ignition SW is set 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 that if work is started within 90 seconds of disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)

When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio systems will be canceled. So before starting work, make a record of the contents memorized by audio memory system. When work is finished, reset the audio system as before and adjust the clock. To avoid erasing the memory of each memory system, never use a back-up power supply from outside the vehicle.

Before repairs, remove the airbag sensors if shocks are likely to be applied to the sensors during repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly directly to hot air or flames.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly and side airbag assembly should be inspected.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly or side airbag assembly sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly side airbag assembly, seat belt pretensioner, airbag sensor assembly or side airbag assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones.

Use a Volt/Ohmmeter with high impedance (10 K Ohms/Volt minimum) for troubleshooting the system's electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.

After work on the SRS is completed, check the SRS warning light check.
