HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Locations of SRS Components
Servicing vehicle with a Supplemental Restraint System (referred to as the SRS in the remainder of this
manual) installed.
When handling SRS components (removal, installation or inspection, etc.), always follow the directions
given in the repair manual for the relevant model year to prevent the occurrence of accidents and airbag
malfunction.
Also take the following precautions when repairing the body:
Work must be started after 90 seconds or longer from the time the ignition switch is set to the LOCK
position and the negative (±) terminal cable is disconnected from the battery.
(The airbag system is equipped with a back±up power source so that if work is started within 90 sec-
onds of disconnecting the negative (±) terminal cable of the battery, the airbag may be deployed.)
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat, outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory function, it is not possible to make a record of
the memory contents. So when the operation is finished, it will be necessary to explain this fact to the
customer, and request the customer to adjust the features and reset the memory.
When using electric welding, first disconnect the SRS connector (yellow color and 2 pins) under the
steering column near the combination switch connector on the glove compartment finish plate and
lower the front scuff plate before starting work.
INTRODUCTIONIN-6
SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.
Malfunction symptoms of the SRS 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 when the ignition switch is turned to the ºLOCKº 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 from
disconnecting the negative (±) terminal cable of the battery, the SRS may be deployed.)
When the negative (±) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each
memory system, never use a back±up power supply from outside the vehicle.
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner,
center airbag sensor assembly, front airbag sensor assembly or side 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, center airbag sensor assembly, front airbag sensor assembly
and side airbag sensor 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, center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly in order to
reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, center airbag
sensor assembly, front airbag sensor assembly or side airbag sensor 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 kW/V 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, perform the SRS warning light check.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

HINT:
When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numeral order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.
