Inflatable Restraint Sensing and Diagnostic Module Replacement (AM6)

CAUTION:
^ Be careful when you handle a sensing and diagnostic module (SDM). Do not strike or jolt the SDM. Before applying power to the SDM:
^ Remove any dirt, grease, etc. from the mounting surface
^ Position the SDM horizontally on the mounting surface
^ Point the arrow on the SDM toward the front of the vehicle
^ Tighten all of the SDM fasteners and SDM bracket fasteners to the specified torque value
Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.
^ If any water enters the vehicle's interior up to the level of the carpet or higher and soaks the carpet, the sensing and diagnostic module (SDM) and the SDM harness connector may need to be replaced. The SDM could be activated when powered, which could cause deployment of the air bag(s) and result in personal injury. Before attempting these procedures, the SIR system must be disabled. Refer to Disabling the SIR System.
With the ignition OFF, inspect the SDM mounting area, including the carpet. If any significant soaking or evidence of significant soaking is detected, you must perform the following tasks:
1. Remove all water.
2. Repair the water damage.
3. Replace the SDM harness connector.
4. Replace the SDM.
Failure to follow these tasks could result in possible air bag deployment, personal injury, or otherwise unneeded SIR system repairs.

Removal Procedure




1. Disable the SIR system. Refer to Air Bag(s) Arming and Disarming.
2. Remove the front split bench seat.
3. Remove the rear carpet from vehicle.




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




6. Remove push-on clip (1) securing SDM wiring harness to console stud.
7. Disconnect the SDM wiring harness connector (3) from the SDM (2).




8. Remove the SDM mounting fasteners (1).
9. Remove the SDM (2) from the console floor (3).

Installation Procedure




1. Install the SDM (2) to console floor (3).

NOTE: Refer to Fastener Notice in Service Precautions.

2. Install the SDM mounting fasteners (1).

Tighten
Tighten fasteners to 9 N.m (80 lb in).




3. Connect the SDM wiring harness connector (3) to the SDM (2).
4. Install push-on clip (1) securing SDM wiring harness to console stud.




5. Push down flex lock button (3) and then move sliding connector locking cover (4) to the close position.
6. Install the Connector Position Assurance (CPA) (1) to the inflatable restraint sensing and diagnostic module (SDM) wiring harness connector (2).




7. Install the rear carpet into vehicle.
8. Install the front split bench seat.
9. Enable the SIR system. Refer to Air Bag(s) Arming and Disarming. 10. After replacing the SDM the new SDM must be programmed into the Dash Integration Module. Refer to Body Control Module (BCM) Programming/RPO Configuration (DIM) or Body Control Module (BCM) Programming/RPO Configuration (IPM) or Body Control Module (BCM) Programming/RPO Configuration (RIM) in Body Control Systems.
