INSTALLATION
1. INSTALL FRONT AIRBAG SENSOR
(a) Install the sensor so that the arrow on the sensor faces
toward the front of the vehicle.
(b) Using a torx wrench, install the sensor with 2 screws.
Torx wrench: T40 (Part No. 09042−00020 or locally
manufactured tool)
Torque: 29 N·m (300 kgf·cm, 22 ft·lbf)
(c) Connect the connector.
NOTICE:
Make sure the sensor is installed to the specified
torque.
If the sensor has been dropped, or there are cracks,
dents or other defects in the case, brackets or con-
nector, replace the removed sensor, always replace
the set bolts with new ones.
The sensor set bolts which have been anti−rust
treated. When the sensor is removed, always replace
the set bolts with new ones.
After installation, shake the sensor to check that
there is no looseness.
The front sensor is equipped with an electrical con-
nection check mechanism. Be sure to lock this mech-
anism securely when connecting the connector . If
the connector is not securely locked, a malfunction
code will be detected by the diagnostic system.

REPLACEMENT
In the following cases,replace the wire harness or connector.
If any part of the SRS wire harness or any connector has been found to be faulty in troubleshoot-
ing.
If any part of the SRS wire harness or any connector has been found to be faulty during the check
in items (See page RS−32).
CAUTION:
If the wire harness used in the SRS is damaged, replace the whole wire harness assembly.
When the connector to the front airbag sensors can be repaired alone (when there is no damage
to the wire harness), use the repair wire specially designed for this purpose.

INSPECTION
1. INSPECT SPEEDOMETER ON−VEHICLE
(a) Using a speedometer tester, inspect the speedometer for
allowable indication error and check the operation of the
odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.
(b) Check the speedometer for pointer vibration and abnor-
mal noise.

2. INSPECT VEHICLE SPEED SENSOR OPERATION
Check that there is continuity between terminals A and B four
times for every revolution of the speedometer shaft.
If operation is not as specified, replace the speedometer.

(b) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:
After the blower motor has stopped, leave the cooling unit
for more than 15 minutes.
Expose the gas leak detector sensor under the drain
hose.
When bring the gas leak detector close to the drain hose,
make sure that the gas leak detector does not react to the
volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
blower resistor from the cooling unit. Then insert the gas
leak detector sensor into the unit and perform the test.
(d) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines
and perform the test.
