Question 1

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

Accepted Answer

The service of front impact severity sensors requires safety glasses to protect from potential air bag deployment injuries. Check the vehicle sensor alignment is in its proper position for correct system function and examine the sensor mounting bracket and wiring pigtail for damage because of collisions. Then repair or reposition the sensor and all damaged SRS components without caring about air bag deployment. The use of memory saver devices should be avoided to decrease the chance of personal injuries. A check of the restraints control module (RCM) fuse together with an ON ignition switch will result in warning lamp illumination but this scenario represents a normal system condition. Before returning the vehicle to the customer, test the complete SRS system for proper functionality and no defects while using new parts for every repair unless diagnostic results show otherwise. Start by powering down the system then put a mark on the hood latch position after removing bolts and loosening hood latch nut before taking out hood latch bolts for assembly placement aside. You must detach pin-type retainers from the wiring harness, remove a bolt from the radiator support bracket, remove the front impact severity sensor bolt and then disconnect the electrical connector along with removing the sensor. Attach the electrical connector to the new front impact severity sensor after you clean the mating surfaces while helping the locator tabs fit into the radiator support bracket openings. After fastening the front impact severity sensor with 12 Nm (9 lb-ft) torque the installation process requires attachment of the radiator support bracket bolt with the same torque. To complete installation mount the hood latch assembly at its proper position while tightening its bolts to 9 Nm (80 lb-in) followed by 9 Nm (80 lb-in) for the hood latch nut. Check if the hood latch striker properly connects to the hood latch before activating system power.

Question 2

How to safely service and repair the Air Bag Sensor on Mercury Cougar?

Accepted Answer

The first step to service and repair the impact sensor requires waiting at least one minute after battery cable detaching to disconnect the electronic air bag control module or any supplemental restraint system electrical connectors to avert unintentional air bag deployment. Installing radio keycode savers poses the risk of air bag deployment when working on the air bag system thus causing personal injury. Safety glasses must be worn for air bag module handling tasks and you must position the live air bag with bag and trim cover facing away from your body to protect yourself from deployment-related injuries. Place an air bag on a surface but orientate it with the trim cover facing the ceiling then clean your hands with soap and water following an air bag release to eliminate skin-irritating sodium hydroxide agents. The required repair method involves installing new components; however if new components fail to address the issue reinstall the original components then commit to repeating diagnostic testing. A probe near air bag module connectors will automatically deploy the air bag which causes injury to technicians. Damaged deployment doors along with discolored air bag modules need to be replaced by brand new components. First step in removing components includes extracting the front seat and scuff plate together with cowl side panel followed by lifting the hood latch release handle and separating both retaining clips. First remove the floor carpet and sound deadening layer before detaching and removing the side bag crash sensor along with its electrical wire. Check that the floor pan space near the crash sensor remains undamaged throughout installation because improper mounting will affect sensor operation and may activate the air bag prematurely. The sensor retaining bolts need replacement by service parts which are different from the used thread-cutting bolts of the original part.
