Inflatable Restraint Sensing and Diagnostic Module (A51/AG1/AG2/AQ9)

INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE REPLACEMENT (A51/AG1/AG2/AQ9)

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 SDM harness connector must be replaced. The SDM could be activated when powered, which could cause airbag deployment and result in personal injury.

1. Disable the SIR system. Refer to SIR Disabling and Enabling Zone 8.




2. Move both the driver and the passenger seat forward and/or to the rear to gain access to the console fasteners.
3. Remove the console.
4. When the console is removed the carpet will be pre-slit to provide access to the inflatable restraint sensing and diagnostic module (SDM).




5. Remove the connector position assurance (CPA) (1) from the inflatable restraint SDM wiring harness connector (2).
6. Push down the flex lock button (3) and then move the sliding connector locking cover (4) to the open position.




7. Remove the push-on clip (1) securing the SDM wiring harness to console stud.
