Impact Sensor: Service and Repair
Forward Discriminating Sensor
Prior to performing replacement procedures, disarm air bag system. Refer to, Service and Repair/ Air Bag System Disarming & Air Bag
System Arming. Refer to, / Specifications/ Mechanical for torque values when installing components.
All sensors and mounting bracket bolts must be carefully torqued to assure proper operation. Never power up the air bag system when any
sensor is not rigidly attached to the vehicle, since the sensor could be activated when not attached, causing air bag deployment.

connector located next to battery.
2. Remove sensor harness from retainers.
3. Remove sensor bolts, then the sensor.
4. Reverse procedure to install. Ensure arrow on sensor is pointing toward front of vehicle.
