Impact Sensor: Service and Repair
Front End Discriminating Sensor
Caution should be used to ensure proper location of sensors to the mounting brackets. The keying of the sensor to the wiring harness connectors must not
be modified for any reason.
CAUTION: During service procedures, be very careful when handling a sensor. Never strike or jar a sensor. Under some circumstances, it
could cause deployment and result in personal injury or improper operation of the Supplemental Inflatable Restraint (SIR) system. All sensors
and mounting bracket bolts must be carefully torqued to assure proper operation. Never power up the SIR system when any sensor is not
rigidly attached to the vehicle since the sensor could be activated when not attached and could result in deployment.
