Circuit/System Testing

WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.

The I/P module
The SDM module
The I/P wiring harness connector
The SDM wiring harness connector

Ignition OFF, disconnect I/P module in-line connector. Refer to Inflatable Restraint Instrument Panel Module Replacement in Repair Instructions for location of connector.
Use J 38715-80 to connect the J 38715-A to the harness side of the I/P module in-line wiring harness connector. See Special Tools . Use the PASSENGER INFLATOR and BASE of COLUMN connectors located on the load tool.
Ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B0012, B0013, B0014, B0016, B0017 or B0018 is current.
- If DTC B0012, B0013, B0014, B0016, B0017 or B0018 is history replace the I/P module. Refer to Inflatable Restraint Instrument Panel Module Replacement in Repair Instructions.
Ignition OFF, disconnect and remove the J 38715-A and adapter. See Special Tools . Then remove the SDM connector, refer to Inflatable Restraint Sensing and Diagnostic Module Replacement SDM replacement in Repair Instructions.
Test the high and low circuits between the SDM and I/P module for a short to voltage, short to ground, an open or low resistance. Verify that a short to voltage, short to ground or open/low resistance does not exist.
- If any of the above conditions are found make the appropriate repair.
If all circuits test normal then replace the SDM.
