# SDM Connector Does Not Mate With Replacement SDM

Subject: | Sensing and Diagnostic Module (SDM) Connector Does Not Mate With Replacement SDM -- Replace Terminal Retainer and Reprogram Body Control Module (BCM)

Models: | All 2000 Saturn L-Series Vehicles

### Condition:

Replacement SDM will not mate with the instrument panel harness connector due to a change in configuration of the terminal retainer.

### Cause:

This condition is caused by the replacement SDM terminal retainer having a different configuration than the original terminal retainer.

### Correction:

Replace the SDM body harness terminal retainer and reprogram the BCM.

### Service Procedure:

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.

• | Tighten all the SDM fasteners and SDM bracket fasteners to the specified torque value.

Failure to follow the correct procedures could cause air bag deployment, personal injury, or unnecessary SIR system repairs.

Notice: If sensing and diagnostic module (SDM) is dropped or shows any sign of damage, it must be replaced.

Notice: Prior to removing sensing and diagnostic module (SDM), the ignition key must be in the OFF position.

Notice: Do not open the sensing and diagnostic module (SDM) case for any reason. Touching the connector pins or soldered components may cause electrostatic discharge damage. Repair of a faulty SDM is by replacement only.

8. Install new SDM terminal retainer P/N 15393727.
9. Install the SDM to the vehicle.
10. Install the SDM retaining nuts.

Tighten:
Tighten the SDM retaining nuts to 10 N·m (89 lb in).
