Ford 6F2Z-14B004-AA
Impact Sensor, Front

Safety glasses must be worn during front impact severity sensor servicing to protect against possible injuries that could occur during accidental air bag deployment. The vehicle sensor needs proper alignment to operate correctly. The inspection process following a collision requires examination of sensor mounting brackets together with wiring pigtails for warping then replacing all supplemental restraint system components alongside the sensor when damage occurs. The air bag warning lamp turns on following the removal of the RCM fuse while the ignition switch is set to ON despite no existence of a system error. All vehicles should receive the supplemental restraint system checks before they return to customers to ensure complete operation without faults. The repair process requires new part installation while the diagnostic procedure should be repeated after reinstallation of the original part when the issue fails to resolve. First remove power from the system while disconnecting the electrical connector linking to the front impact severity sensor. The two securing nuts should be removed from the sensor before installation where you should tighten them to 12 Nm (9 lb-in) torque setting. First remove the front impact severity sensor with caution while checking for any debris or dirt on the surfaces that connect to the radiator support. The process completion involves returning to the removal steps followed by system repowering.

Professional servicing of the right-hand side C-pillar side impact sensor requires safety glasses for protection along with no usage of memory saver devices. The air bag warning lamp will turn on due to the removal of the RCM fuse during the ON state of the ignition switch but this condition is acceptable and signals no fault in the system. The supplemental restraint system needs to operate without faults before you give the vehicle back to the customer. Diagnostics should be performed once again after reinstalling the original part while addressing persistent issues through new part installation. System depowering starts before the removal of rear door scuff plate and safety belt anchor bolt to tighten it to 40 Nm (30 lb-ft). Begin by removing the quarter trim panel near the C-pillar to reach the side impact sensor after disconnecting all retaining clips as well as the weather strip if needed. Unplug the sensor electrical connector before unstowing it with two bolts that require torques to 12 Nm (9 lb-ft) during the reinstallation. A proper inspection must validate that safety belt webbing remains untwisted before mounting the sensor. Reverse the uninstall process and activate the system power to verify proper function of the active restraint system.

Always wear safety glasses to minimize injury risk from accidental air bag deployment and avoid using memory saver devices.

Ensure the SRS is fully operational and free of faults.

Begin by depowering the system.

It indicates that the RCM fuse has been removed with the ignition switch in the ON position, which is normal and does not indicate an SRS fault.

Avoid using memory saver devices.

Carefully remove the front impact severity sensor, making sure the radiator support and sensor mating surfaces are clean and free of debris.
