Q: How Should the Side Impact Air Bag Sensor Be Serviced to Ensure Safety and Proper Functionality on Mercury Grand Marquis?
A: Safety glasses should always be worn when serving the side impact sensor because it protects against potential air bag-related injuries and prevents the use of memory saver devices. The correct position of Vehicle sensors depends on system function so a post-collision check should inspect both sensor brackets and wiring pigtail for deformities but replacements and restorations should occur regardless of air bag deployment. The RCM fuse removal will cause the air bag warning lamp to turn on while the ignition switch is ON but this condition does not imply any system fault. Thoroughly check the SRS system for all faults before giving the vehicle back to the customer. Repair procedures require new parts installation and you should retest after reinstallation of the original component. Each side impact sensor exists at the base of the B-pillars. Depower the system before you remove the driver side front scuff plates and rear scuff plates followed by the B-Pillar weather stripping on the same side. To take off the driver side B-pillar lower trim panel users must first release its retaining clips. Unbolt the specified sequence of side impact sensor fasteners and detach the electrical wire before removing the sensor with the bracket. The installation process requires proper torque retention of air bag side impact sensor retaining bolts together with sequential sensor insertion after reconnecting the electrical connector and returning restored trim panel together with weather stripping and scuff plates before the system powering up.
Q: How to safely service and repair the side impact air bag sensor on Mercury Cougar?
A: The first step to service or repair the side impact sensor requires waiting one minute after battery cable removal to avoid accidental air bag deployment during electronic air bag control module or supplemental restraint system electrical connector removal. You must not use radio keycode savers on the air bag system repairs and you need to wear safety glasses for working with the air bag module. Safety-first mandates that you should handle the air bag module by pointing the bag with trim cover up while positioning it on a flat surface. Congratulations to your task is solved you should then wash your hands with soap under running water to clear away remaining sodium hydroxide residues. The diagnostic requires adding a new part first and reverting to the original part after failed testing when repeating the steps. Technicians must refrain from probing air bag connectors while they should avoid repainting damaged air bag modules and should always install fresh components whenever discolored or ruined covers and deployment doors are present. Commence the extraction process by removing both the front seat along with scuff plate and cowl side panel. Subsequently operate the hood latch handle and pop off the two retaining fasteners. Begin the procedure by removing floor coverings as well as carpet and then disconnect the electrical connector to take out the side air bag crash sensor. The improper mounting of the crash sensor next to the floor pan area produces incorrect sensor operation which could potentially trigger early air bag deployments. Verify the floor pan area shows no damage before sensor installation. The technician should replace sensor retaining bolts exclusively with service replacements because the original bolts need to stay personal.
Q: How to Service the Air Bag Sensor in the Second Row, C-Pillar on Mercury Mariner?
A: The service procedure for the second-row C-pillar side impact sensor requires first verifying the vehicle has not experienced a crash. If the vehicle has been in a crash service the restraints control module (RCM) and impact sensor mounting locations for deformation and restore them to their original design if necessary. New RCM and sensors must be installed regardless of air bag activation because of injury risks in a crash situation. The installation of new RCM sensors together with sensors is mandatory regardless of air bag deployment status because it prevents fatal injuries or death in a crash. The procedure should start with disarming all components of the Supplemental Restraint System (SRS) before proceeding. The first step involves removing the C-pillar trim panel followed by disconnecting its electrical connector before removing the side impact sensor bolt. Install the bolt with 6 Nm (53 lb-in) of torque when re-installing it. Follow the specified torque values when fastening the RCM and impact sensor because improper system operation can result. Clean both mating surfaces of the C-pillar and side impact sensor eliminating any present debris. The completion of the installation requires activating power to the SRS.
