When SRS is not activated in a collision

FOR SIDE AND ROLLOVER COLLISION: When SRS is not activated in a collision

caution

Due to varying models and option levels, not all parts listed in the chart below apply to all vehicles.

WORK PROCEDURE

1. Before performing any of the following steps, ensure that all vehicle body and structural repairs have been completed.

2. Check the SRS components and the related parts using the following table.

If the front seatback assembly is damaged, the front seatback assembly must be replaced.
If the rear seatback assembly is damaged, the rear seatback assembly must be replaced.

3. Perform Diagnostic Trouble Code using M.U.T.-III SE and "AIR BAG" warning light. Refer to DTC Index

for details. Make sure entire SRS operates properly.

4. After the work is completed, check that no malfunction is detected by air bag warning light.

SRS INSPECTION (FOR SIDE AND ROLLOVER COLLISION)

Part	Inspection
Side curtain air bag module LH	If the side curtain air bag LH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the center pillar on the collision side. If damaged - Remove the side curtain air bag module LH. Check for visible signs of damage (tears etc.) of the side curtain air bag module LH. Check harness and connectors for damage, and terminals for deformities. If no damage is found, reinstall the side curtain air bag module LH. If damaged - REPLACE the side curtain air bag module LH.
Side curtain air bag module RH	If the side curtain air bag RH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the center pillar on the collision side. If damaged - Remove the side curtain air bag module RH. Check for visible signs of damage (tears etc.) of the side curtain air bag module RH. Check harness and connectors for damage, and terminals for deformities. If no damage is found, reinstall the side curtain air bag module RH. If damaged - REPLACE the side curtain air bag module RH.
Front side air bag module LH	If the front side air bag LH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the seatback on the collision side. Check harness and connectors for damage, and terminals for deformities. If damaged - REPLACE the front seatback assembly LH.
Front side air bag module RH	If the front side air bag RH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the seatback on the collision side. Check harness and connectors for damage, and terminals for deformities. If damaged - REPLACE the front seatback assembly RH.
Front center air bag module	If the front center air bag has not deployed: Check for visible signs of damage (dents, tears, deformation) of the seatback on the collision side. Check harness and connectors for damage, and terminals for deformities. If damaged - REPLACE the front seatback assembly RH.
Rear side air bag module LH	If the rear side air bag LH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the seatback on the collision side. Check harness and connectors for damage, and terminals for deformities. If damaged - REPLACE the rear seatback assembly.
Rear side air bag module RH	If the rear side air bag RH has not deployed: Check for visible signs of damage (dents, tears, deformation) of the seatback on the collision side. Check harness and connectors for damage, and terminals for deformities. If damaged - REPLACE the rear seatback assembly.
Side air bag (satellite) sensor (LH or RH)	If none of the SRS components have been activated: Remove the side air bag (satellite) sensor (LH or RH) on the collision side. Check harness connectors for damage, terminals for deformities, and harness for binding. Check for visible signs of damage (dents, cracks, deformation) of the side air bag (satellite) sensor (LH or RH). Install the side air bag (satellite) sensor (LH or RH) to check fit. If no damage is found, reinstall the side air bag (satellite) sensor (LH or RH). If damaged - REPLACE the side air bag (satellite) sensor (LH or RH).
Door (satellite) sensor (LH or RH)	If none of the SRS components have been activated: Remove the door (satellite) sensor (LH or RH) on the collision side. Check harness connectors for damage, terminals for deformities, and harness for binding. Check for visible signs of damage (dents, cracks, deformation) of the door (satellite) sensor (LH or RH). Install the door (satellite) sensor (LH or RH) to check fit. If no damage is found, reinstall the door (satellite) sensor (LH or RH). If damaged - REPLACE the door (satellite) sensor (LH or RH).
Diagnosis sensor unit	If none of the SRS components have been activated: Check case and bracket for dents, cracks or deformities. Check connectors for damage, and terminals for deformities. If no damage is found, reinstall the diagnosis sensor unit. If damaged - REPLACE the diagnosis sensor unit.
Seat belt pre-tensioner assemblies (All applicable locations: buckle, retractor, lap outer)	REPLACE the seat belt pre-tensioner assembly.
Seat (with front side air bag)	If the front LH or front RH side air bag modules have not deployed: Visually check the seat on the collision side. Remove the seat on the collision side and check the following for damage and deformities. Harness, connectors and terminals Frame and recliner (for front and rear seat), and also adjuster and slides (for front seat) If no damage is found, reinstall the seat. If damaged - REPLACE the damaged seat parts using new fasteners. If the front seatback is damaged, the front seatback assembly must be replaced.
Seat (with front center air bag)	If the front center air bag module have not deployed: Visually check the drive's side seat. Remove the drive's seat and check the following for damage and deformities. Harness, connectors and terminals Frame and recliner (for front and rear seat), and also adjuster and slides (for front seat) If no damage is found, reinstall the driver's seat. If damaged - REPLACE the damaged seat parts using new fasteners. If the front seatback is damaged, the front seatback assembly must be replaced.
Center inner pillar	Check the center inner pillar on the collision side for damage (dents, cracks, deformation, etc.). If damaged - REPAIR the center inner pillar.
Trim/headlining	Check for visible signs of damage (dents, cracks, deformation, etc.) of the interior trim on the collision side. If damaged - REPLACE the damaged trim parts.
Occupant detection system (Passenger seat)	Remove passenger seat assembly. Check control unit case for dents, cracks of deformities. Check connectors for damage and terminals for deformities. Check seat frame and cushion pan for dents or deformities. If no damage is found, reinstall seat. If damaged - REPLACE the seat cushion assembly. Perform zero point reset function after front passenger seat is installed in the vehicle and all bolts are tightened to specification. Refer to Work Procedure.
