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
Caution: 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:- Remove all water.
- Repair the water damage.
- Replace the SDM harness connector.
- Replace the SDM.
Removal Procedure
- Disable the SIR system. Refer to Disabling the SIR System .
- Move both driver and passenger seat forward and/or to the rear to gain access to console fasteners.
- Remove the console. Refer to Front Floor Console Replacement in Instrument Panel, Gages and Console.
- When the console is remove the carpet will be pre-slit to provide access to the inflatable restraint sensing and diagnostic module (SDM).
- Remove the connector position assurance (CPA) (1) from the SDM wiring harness connector (2).
- Push down flex lock button (3) and then move sliding connector locking cover (4) to the open position.
- Remove push-on clip (1) securing SDM wiring harness to console stud.
- Disconnect the SDM wiring harness connector (3) from the SDM (2).
- Remove the SDM mounting fasteners (1).
- Remove the SDM (2) from the console floor (3).
Installation Procedure
- Install the SDM (2) to console floor (3).
- Install the SDM mounting fasteners (1).
- Connect the SDM wiring harness connector (3) to the SDM (2).
- Install push-on clip (1) securing SDM wiring harness to console stud.
- Push down flex lock button (3) and then move sliding connector locking cover (4) to the close position.
- Install the connector position assurance (CPA) (1) to the SDM wiring harness connector (2).
- Install the carpet pre-slit to the close position covering the SDM.
- Install the console. Refer to Front Floor Console Replacement in Instrument Panel, Gages and Console.
- Install the driver and passenger seat to the original position.
- Enable the SIR system. Refer to Enabling the SIR System .
- Program the SDM. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten fasteners to 9 N·m (80 lb in).
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.
