INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE REPLACEMENT
REMOVAL PROCEDURE
CAUTION:
- Do not strike or jolt the inflatable restraint sensing and diagnostic module (SDM). Before applying power to the SDM, make sure that it is securely fastened with the arrow facing toward the front of the vehicle. Failure to observe the correct installation procedure could cause SIR deployment, personal injury, or unnecessary SIR system repairs.
- If the vehicle interior is exposed to moisture and becomes soaked up to the level of the sensing and diagnostic module (SDM), the SDM and the SDM harness connector must be replaced. The SDM could be activated when powered, which could cause the airbag deployment and result in personal injury.
1. Disable the SIR system. Refer to SIR Disabling and Enabling Zone 8 in Restraint Systems.
2. Remove the console.
3. Remove the inflatable restraint sensing and diagnostic module nuts.
4. Remove the inflatable restraint sensing and diagnostic module wire harness connector.
5. Remove the inflatable restraint sensing and diagnostic module.
INSTALLATION PROCEDURE
1. Point the arrow on the SDM toward the front of the vehicle.
2. Install the inflatable restraint sensing and diagnostic module.
3. Install the inflatable restraint sensing and diagnostic module wire harness connector.
NOTE: Refer to Fastener Notice in Service Precautions.
4. Install the inflatable restraint sensing and diagnostic module nuts.
Tighten
Tighten the nuts to 10 N.m (89 lb in).
5. Install the console.
IMPORTANT: The AIR BAG indicator may remain ON after the SDM has been replaced. DTC B1001 may set requiring the SDM part number to be set in multiple modules. If the indicator remains ON after enabling the SIR system, perform the diagnostic system check and follow the steps thoroughly to ensure that the SDM is set properly.
6. Enable the SIR system. Refer to SIR Disabling and Enabling Zone 8 in Restraint Systems.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
