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.


1. Disconnect sensor electrical connector from retainer, then remove connector from Connector Position Assurance (CPA) lock and disconnect.
2. Remove sensor mounting bolts, then the sensor from vehicle.
3. Reverse procedure to install. Ensure arrow is pointed toward front of vehicle.
