Wiring Diagram:

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.

NOTICE: When DTC B1018 or B1024 has been set it is necessary to replace the SDM. Setting DTC B1018 or B1024 will also cause DTC B1071 to set. When a scan tool CLEAR CODES command is issued and the malfunction is no longer present, DTC B1018 or B1024 and DTC B1071 will remain current. Make sure that the short-to-ground condition is repaired prior to installing a replacement SDM to avoid damaging the SDM.
