Removal Procedure

1. Disable the frontal SIR system.
2. Remove the driver seat.
3. Remove the right side sill plate.
4. Lift up the carpet and insulation in order to access the Inflatable Restraint Sensing and Diagnostic Module (SDM).
5. Remove the Connector Position Assurance (CPA) (4) from the SDM harness connector (3).




6. Disconnect the SDM harness connector 7 (3) from the SDM (1).





7. Remove the SDM mounting fasteners (6).
8. Remove the SDM (1) from the floor sheetmetal (2).

Important: The following repair procedures should only be used in the event that the Inflatable Restraint Sensing and Diagnostic Module (SDM) mounting studs and/or fasteners are damaged to the extent that the SDM can no longer be properly mounted.

9. Utilize the following procedures if the SDM mounting fasteners or the SDM attachments are damaged:
^ If the SDM mounting bracket is broken loose from the floor sheetmetal at the weld, mig weld the bracket using the puddle weld method on the spots that have broken loose. Always weld the bracket in the same spots as the original welds.

Notice: Refer to Fastener Notice in Cautions and Notices.

^ If an SDM attachment nut is missing or broken, slip a loose nut (PN 11515741) under the SDM bracket. While you hold the nut in place, install the bolt (PN 11515925).

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

^ If the ground wire nut is missing, Drill the 8 mm (0.315 in) hole in the bracket to 12 mm (0.472 in). Tack weld a loose weld nut (PN 20530601) to the bracket in place of the missing nut. Fasten the ground wire using the original bolt (PN 3578880).

Tighten
Tighten fasteners to 6 N.m (54 lb in).

^ If the SDM attachment nut or ground nut is stripped, drill a 6.5 mm (0.256 in) hole through the weld nut. Use a new 7 mm bolt (PN 10267482) in order to fasten the SDM or the ground wire.

Tighten
Tighten fasteners to 16 N.m (12 lb ft).

^ If the SDM attachment bolt or ground bolt is broken, use a tap, bolt remover or drill in order to remove the broken bolt. Drill a 6.5 mm (0.256 in) hole through the weld nut. Use a new 7 mm bolt (PN 10267482) in order to fasten the SDM or the ground wire.

Tighten
Tighten fasteners to 16 N.m (12 lb ft).
