WARNING:
Do not handle, move or change the original horizontal
mounting position of the Restraints Control Module (RCM) while the
Restraints Control Module (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 the Ford parts catalog to make sure the correct
component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
|
NOTE:
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
