INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE REPLACEMENT

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
