2006 Mercury Mariner Air Bag Sensor Parts Questions & Experts Answers

• Q: How Should the Front Air Bag Sensor Be Serviced to Ensure Safety and Proper Operation on 2006 Mercury Mariner?

  A: Safety glasses should be worn when servicing the front impact severity sensor because accidental air bag deployment creates injury risks. You must verify that vehicle sensors maintain correct orientation to work properly before inspecting the mounting bracket and wiring pigtail for damage caused by accidents. All damaged components need replacement even if air bags did not activate during the accident. The use of memory saver devices must be avoided at all times. The air bag warning lamp will flash during ignition ON conditions while the RCM fuse is extracted but no SRS failure exists. Any customer return of this vehicle means the SRS system must function flawlessly. The repair process requires new part installation followed by reinstallation of the original component while executing another diagnostic check. Start the process by disconnecting power from the system while labeling the hood latch location then remove the bolts. Detach the hood latch nut then remove the bolts from the hood latch before moving the part to a set location. First disconnect the pin-type retainers on the wiring harness and remove the radiator support bracket bolt followed by the front impact severity sensor bolt. First disconnect the electrical connector after which you should remove the front impact severity sensor. To install the front impact severity sensor you should connect the electrical connector to it after ensuring that both mating surfaces remain clean. Position the locator tabs of the sensor through its appropriate openings on the radiator support bracket before securing the sensor bolt at 12 Nm (9 lb-ft). The radiator support bracket bolt requires installation followed by tightness to 12 Nm (9 lb-ft) while the wiring harness pin-type retainers need to be attached. The position of hood latch should match the previous mark while installation of hood latch takes place with bolt torques set to 9 Nm (80 lb-in) before tightening the hood latch nut to identical specification. Review that the hood latch has complete engagement by confirming correct alignment between the hood latch striker and then activate system power.
