Removal Procedure
- Disable the SIR system. Refer to SIR Disabling and Enabling .
- Remove the connector position assurance (CPA) from the wiring harness connector to the inflatable restraint front end sensor (2).
- Disconnect the wiring harness connector from the front end sensor (2).
- Loosen the front end sensor mounting fastener (1), which is located in the upper tie bar.
- Remove the front end sensor (2) from the upper tie bar.
Caution: Refer to SIR Caution in the Preface section.
Caution: Do not strike or jolt the inflatable restraint front end sensor. Before applying power to the front end sensor make sure that it is securely fastened. Failure to observe the correct installation procedure could cause SIR deployment, personal injury, or unnecessary SIR system repairs.
Important: The front end sensor mounting fastener (1) has left handed threads.
Installation Procedure
- Remove any dirt, grease, or other impurities from the mounting surface.
- Position the sensor (2) horizontally on the mounting surface.
- Point the arrow on the sensor toward the front of the vehicle.
- Install the mounting fasteners.
- Connect the harness wiring connector to the front end sensor.
- Install the CPA to the wiring harness connector on the front end sensor.
- Enable the SIR system. Refer to SIR Disabling and Enabling .
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the fastener (1) to 9 N·m (80 lb in).
