Caution: Be very careful when handling the sensors during service procedures. Never strike the sensors. Never jar the sensors. These actions could result in personal injury, or improper operation of the Supplemental Inflatable Restraint (SIR) system.

Carefully tighten all of the sensors, and all of the mounting bracket bolts to ensure proper operation. Never power up the SIR system when any one of the sensors is not rigidly attached to the vehicle An unattached sensor could be easily activated causing the deployment of the air bag.
Use caution to ensure proper location of sensor on the mounting brackets. Do not for any reason modify the keying of the sensors through the wiring harness connectors.
1. Disable the SIR system. Refer to Air Bag(s) Arming and Disarming.
2. Disconnect the Connector Position Assurance (CPA) lock from the connector.
