REMOVAL
1. DISCONNECT SPEED SENSOR CONNECTOR
2. REMOVE SPEED SENSOR
(a) Remove the clamp bolt, the clamp nut and the 5 clips
holding the sensor wire harness from the axle and the fuel
tank.
HINT:
When installing the rear sensor wire harness, never use
the removed resin clips, which are service parts.
When replacing clips, set up new resin clips at the same
angle of the removed resin clips.
When removing a resin clip, take care so that the remov-
ing tool is not caught on the grommet or wire.
Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(b) Remove the speed sensor from the axle carrier.
Torque: 8.0 N·m (82 kgf·cm, 71 in.·lbf)

PRECAUTION
NOTICE:
The TOYOTA T100 is equipped with SRS, which comprises a driver airbag. Failure to carry out
service operations in the correct sequence could cause the SRS to unexpectedly deploy during
servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the
SRS, it is possible that the SRS may fail to operate when required. Before performing servicing
(including removal or installation of parts, inspection or replacement), be sure to read the fol-
lowing items carefully, then follow the correct procedures described in the repair manual.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, air-
bag sensor assembly and front airbag sensor should be inspected (See page RS−9, RS−23 and
RS−28).
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, airbag sensor assembly or front airbag
sensor in order to reuse it.
If the steering wheel pad, airbag sensor assembly or front airbag sensor 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 kΩ/V minimum) for troubleshooting the system’s
electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.
After work on the SRS is completed, perform the SRS warning light check or SRS side airbag
warning light check (See page DI−365).
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:
Work must be started after 90 seconds from when 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 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 mem-
orized 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, airbag sensor assembly or front airbag sensor directly
to hot air or flames.

OPERATION
1. STEERING WHEEL PAD (with AIRBAG)
The inflater and bag of the SRS are stored in the steering wheel
pad and cannot be disassembled. The inflater contains a squib,
igniter charge, gas generant, etc., and inflates the bag when
instructed by the airbag sensor assembly.
2. SPIRAL CABLE (in COMBINATION SWITCH)
A spiral cable is used as an electrical joint from the vehicle body
side to the steering wheel.
3. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operation conditions when the ignition switch is turned to the
ACC or ON position, the light goes on for about 6 seconds and
then goes off.
4. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
lower center cover. The airbag sensor assembly consists of an
airbag sensor, safing sensor, diagnosis circuit, ignition control,
drive and circuit, etc.
It receives signals from the airbag sensor and judges whether
the SRS must be activated or not.
