  Q: What Precautions Should Be Taken When Servicing the First Row B-Pillar Side Impact Air Bag Sensor on Mercury Montego?

  A:

  Wear safety glasses at all times when servicing the side impact sensor placed in the first row of the B-pillar because accidental air bag deployment poses a risk of injury. The sensor orientation needs correct placement for system operation while sensor mounting bracket and wiring pigtail need replacement if any deformation exists even without air bag deployment after a collision. Supplemental restraint system components must get proper repositioning during this process. The use of memory saver devices leads to increased personal injury risks so these should be avoided. Meanwhile the air bag warning lamp will turn on for normal reasons while the RCM fuse is removed and the Ignition Switch is in ON position. Prior to returning any vehicle to the customer the SRS needs to work properly without any detected faults. The technician needs to install a new component as part of the repair; in case the problem stays unresolved they should return to the original part and perform diagnostic checks again. Start by ripping system power then take away the B-pillar section trim panel while removing the side impact sensor electrical connector. The proper functioning of the air bag side impact sensor depends on correct torques applied to its retaining bolt therefore keep mating surfaces clean from debris. Read the location of the locator tab on the sensor for simpler installation. The side impact sensor retaining bolt must be removed with proper tightening of 12 Nm (9 lb-ft) to detach the side impact severity sensor. Proceed by following the sequence of removal steps after sensor installation to restore system power.
