Crash zone sensor If any of the front air bags or seat belt pre-
tensioners* have
been activated:
REPLACE the crash
zone sensor and
bracket with new fas-
teners.
*: Confirm seat belt
pre-tensioner activa-
tion using CONSULT-
III only. If the front air bags or seat belt pre-tensioners have NOT been activated:
1. Remove the crash zone sensor. Check harness connectors for damage, termi-
nals for deformities, and harness for binding.

Seat belt pre-tension-
er assemblies
(All applicable loca-
tions: buckle, reel, lap
outer) If either the driver or
passenger seat belt
pre-tensioner* has
been activated:
REPLACE all seat
belt pre-tensioner as-
semblies with new
fasteners.
*: Confirm seat belt
pre-tensioner activa-
tion using CONSULT-
III only. If the pre-tensioners have NOT been activated:
1. Remove seat belt pre-tensioners.
Check harness cover and connectors for damage, terminals for deformities, and
harness for binding.
2. Check belts for damage and anchors for loose mounting.
3. Check retractor for smooth operation.
4. Check seat belt adjuster for damage.
5. Check for deformities of the center pillar inner.
6. If the center pillar inner has no damage, REPLACE the seat belt pre-tensioner assembly.
7. If no damage is found, reinstall seat belt pre-tensioner assembly.
8. If damaged—REPLACE. Install the seat belt pre-tensioners with new fasteners.
Diagnosis sensor unit If any of the SRS com- ponents have been
activated:
REPLACE the diag-
nosis sensor unit.
Install with new fas-
teners. If none of the SRS components have been activated:
1. Check case for dents, cracks or deformities.
2. Check connectors for damage, and terminals for deformities.
3. If no damage is found, reinstall with new fasteners.
4. If damaged—REPLACE. Install diagnosis sensor unit with new fasteners.
19, " SRS Operation Check " .
WHEN SRS IS ACTIVATED IN THE SIDE OR ROLLOVER COLLISION
1. Replace the following components:
- Front seat back assembly (on the side on which side air bag is activated)
- Diagnosis sensor unit
- (LH or RH) side air bag (satellite) sensor (on the side on which side air bag is activated)
2. Check the SRS components and the related parts using the following table.
- Replace any SRS components and the related parts showing visible signs of damage (dents, cracks, deformation).

A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure signal transmitted by the transmitter in each wheel.
COMBINATION METER The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
TIRE PRESSURE WARNING CHECK CONNECTOR The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CON-
SULT-III. Refer to WT-17, " Self-Diagnosis (Without CONSULT-III) " . The tire pressure warning check connector
is located behind the lower portion of the instrument panel LH. Refer to PG-38, " Harness Layout " . WEIA0186E
