Sensing and Diagnostic Module Handling Caution

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.
