REMOVAL
CAUTION:
Before servicing, turn ignition switch OFF, disconnect both battery terminal and wait at least 3
minutes.
Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the each
harness connector of the air bag module and pre-tensioner seatbelt to prevent air bag deployment
by static electricity and pre-tensioner seatbelt operation.
Do not use air tools or electric tools for servicing.
Do not use old fixing bolts after removal; replace with new bolts.
Do not make an impact to the diagnosis sensor unit by dropping etc. Replace the diagnosis sen-
sor unit if it has been dropped or sustained an impact.
Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-
tensioner.
1. Remove the diagnosis sensor unit.
Disconnect each connector of all air bag modules and pre-tensioner seat belts.
Remove the center console assembly. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
Disconnect diagnosis sensor unit harness connector.
Remove hex bolts and ground bolt, then remove the diagno-
sis sensor unit.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Be careful not to damage the diagnosis sensor harness.
After the work is completed, make sure no system malfunction is detected by air bag warning
lamp.
In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis func-
tion and delete the memory by CONSULT
ll.
In case that malfunction is still detected after the above operation, perform self-diagnosis to repair
malfunctions. Refer to SRS-19, "
SRS Operation Check" .
ECU DISCRIMINATED NO.
After replacing the diagnosis sensor unit, confirm that the diagnosis sensor unit identification is correct for the
vehicle as equipped.Hex bolts

COLLISION DIAGNOSISPFP:00015
For Frontal CollisionNHS0009L
To repair the SRS, perform the following steps.
When SRS (except the front side air bag and side curtain air bag modules) is activated in a collision:
1. Replace the diagnosis sensor unit.
2. Remove the air bag modules (except the front side air bag modules and side curtain air bag modules),
crash zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
3. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
4. Install new air bag modules (except the front side air bag modules and side curtain air bag modules) crash
zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
5. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When SRS is not activated in a collision:
1. Check the SRS components using the table below:
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When only one front air bag module is activated in a collision:
1. Replace the following components:
–Diagnosis sensor unit
–Crash zone sensor
–Activated front air bag and seat belt pre-tensioner.
2. Check the other SRS components using the table below (Refer to “SRS is NOT activated”).
–Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
3. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
Only one front air bag may inflate a crash, depending on the crash severity and whether the front occupants
are belted or unbelted. This does not indicate improper performance of the system. Perform self-diagnosis to
make sure the entire SRS operates properly.
