Inflatable Restraint Sensing and Diagnostic Module Replacement A51/AG1/AG2/AQ9
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.
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.
Failure to follow these tasks could result in possible air
bag deployment, personal injury, or otherwise unneeded SIR system repairs.
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 removed 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 inflatable restraint sensing and diagnostic module (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).
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.
- Install the SDM mounting fasteners (1).
Tighten
Tighten fasteners to 9 N·m (80 lb in).
- 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 inflatable
restraint sensing and diagnostic module (SDM) wiring harness connector (2).
- Install the carpet pre-slit to the close position covering the inflatable restraint
sensing and diagnostic module (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
.
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.
- Program the SDM. Refer to
Body Control Module (BCM) Programming/RPO Configuration
in Body Control Systems.
