FOR SIDE AND ROLLOVER COLLISION: When SRS is not activated in a collision
cautionDue 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.
  • If the door finisher assembly is damaged, the door finisher assembly and door-mounted curtain air bag module must be replaced.
3. Perform self-diagnosis using M.U.T.-III SE and “AIR BAG” warning light. Refer to DTCIndexDTC 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.
