Initial Inspection and Diagnostic Overview

CAUTION: Certain SRS components must be replaced after a frontal crash involving air bag deployment.

In all types of accidents regardless of "Air Bag" deployment, visually inspect all of the following components and replace as required:
- Driver air bag assembly
- Passenger air bag assembly
- Steering wheel
- SRS coil assembly
- Steering column
- Knee bolster and instrument panel mounting attachments
- Driver seat and belt
- Passenger seat and belt
- SDM

Be sure to replace Sensing and Diagnostic Module (SDM) in accordance with "SDM Replacement Guidelines". In cases of collision without causing air bag deployment, SDM could be used unless this manual instructs to replace.

CAUTION: Refer to SDM Replacement Guidelines below for important information on SDM replacement in both deployment and non-deployment crashes.

SDM Replacement Guidelines
In case that the air bag has been deployed, replace the SDM.
When DTC 51, 53 and 71 are set.
When SDM fell down from a 100 cm (3.3 feet) height.

All above is SDM replacement Guideline.
Inspection is needed also on the following.
1. Inspect Supplemental Restraint System (SRS) coil assembly wiring and steering wheel for any signs of scorching meting or damage due to excessive heat. If coil assembly wire or steering wheel is damaged replace them. The steering column and wheel must be dimensionally checked to determine if they are damaged.
2. Never use SRS parts from another vehicle. This does not include remanufactured parts purchased from an authorized Retailer they may be used for SRS repairs. Do not attempt to repair the SDM, the SRS harness, the SRS coil assembly, the air bag assembly, the steering wheel, or the steering column. Service of these items is replacement only.
3. Verify replacement part numbers.

CAUTION: Proper operation of the SDM and Supplemental Restraint System (SRS) requires that any repairs to the vehicle structure return it to its original production configuration.
