WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS  components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS  .
NOTE: Always make sure the correct SRS  component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS  component is installed, DTCs  may set.
NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter
NOTE: The SRS  must be fully operational and free of faults before releasing the vehicle to the customer.
