COLLISION DIAGNOSISPFP:00015
For Frontal CollisionEHS001SN
Check the SRS components using the following table.
After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to
SRS-20, "
SRS Operation Check" .
SRS INSPECTION (FOR FRONTAL COLLISION)
Part SRS is activated SRS is NOT activated
Driver air bag module If the driver air bag
has deployed:
REPLACE
Install with new fas-
teners.If the driver air bag has NOT been activated:
1. Remove driver air bag module. Check harness cover and connectors for damage,
terminals for deformities, and harness for binding.
2. Install driver air bag module into the steering wheel to check fit and alignment with
the wheel.
3. If no damage is found, reinstall with new fasteners.
4. If damaged—REPLACE. Install driver air bag modules with new fasteners.
Front passenger air
bag moduleIf the front passenger
air bag has deployed:
REPLACE
Install with new fas-
teners.If the front passenger air bag has NOT been activated:
1. Remove front passenger air bag module. Check harness cover and connectors for
damage, terminals for deformities, and harness for binding.
2. Install front passenger air bag module into the instrument panel to check fit with the
instrument panel.
3. If no damage is found, reinstall with new fasteners.
4. If damaged—REPLACE. Install front passenger air bag modules with new fasten-
ers.
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-
II 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, terminals
for deformities, and harness for binding.
2. Check for visible signs of damage (dents, cracks, deformation) of the crash zone
sensor and bracket.
3. Install the crash zone sensor to check fit.
4. If no damage is found, reinstall with new fasteners.
5. If damaged—REPLACE the crash zone sensor and bracket with new fasteners.
Seat belt pre-ten-
sioner 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
assemblies with new
fasteners.
*: Confirm seat belt
pre-tensioner activa-
tion using CONSULT-
II 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
components 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.

COLLISION DIAGNOSIS
Revision: October 20052005 QX56
For Side and Rollover CollisionEHS001SO
Check the SRS components using the following table.
After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to
SRS-20, "
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).
3. Conduct self-diagnosis using CONSULT-II and “AIR BAG” warning lamp. Refer to SRS-20, "
SRS Opera-
tion Check" for details. Ensure entire SRS operates properly.
WHEN SRS IS NOT ACTIVATED IN THE SIDE OR ROLLOVER COLLISION
1. Check the SRS components and the related parts using the following table.
–If the front seat back assembly is damaged, the front seat back assembly must be replaced.
2. Conduct self-diagnosis using CONSULT-II and “AIR BAG” warning lamp. Refer to SRS-20, "
SRS Opera-
tion Check" for details. Ensure entire SRS operates properly.
Steering wheel 1. Visually check steering wheel for deformities.
2. Check harness (built into steering wheel) and connectors for damage, and terminals for deformities.
3. Install driver air bag module into the steering wheel to check fit and alignment with the wheel.
4. Check steering wheel for excessive free play.
5. If no damage is found, reinstall.
6. If damaged—REPLACE.
Spiral cable If the driver front air
bag has deployed:
REPLACE the spiral
cable.If the driver front air bag has not deployed:
1. Visually check spiral cable and combination switch for damage.
2. Check connectors and protective tape for damage.
3. Check steering wheel for noise, binding or heavy operation.
4. If no damage is found, reinstall.
5. If damaged—REPLACE.
Occupant classifica-
tion system (Passen-
ger seat)1. Remove passenger seat.
2. Check control unit case for dents, cracks of deformities.
