ISSUE:
Some vehicles may experience the air bag diagnostic light flashing. The air bag warning indicator may flash as follows:
^
Five (5) flashes, followed by
^
1 second pause, followed by
^
a single flash, then
^
the sequence repeats itself.
This may be caused by a short-to-ground or intermittent short-to-ground in the air bag wiring. Air bag diagnostic monitors displaying Fault Code 51 are
repeatedly being replaced without having first corrected a possible short-to-ground or intermittent short-to-ground in the system.
ACTION:
Deactivate the air bag system and check for and repair any possible shorts-to-ground in the air bag wiring. Replace Diagnostic Air Bag Monitor,
reactivate the system and perform an air bag system prove-out. Refer to the following for detailed service procedures.

General Information
The diagnostic monitor contains an internal thermal fuse that is not serviceable. The thermal fuse is controlled by a computer inside the diagnostic
monitor. The computer will open the thermal fuse whenever a short on the deployment circuits occur. The thermal fuse does not open because of
excessive current flowing through it. Do not attempt to jump the thermal fuse with a circuit breaker or any other type of fuse.
WARNING:
DO NOT INSTALL A NEW DIAGNOSTIC MONITOR UNTIL THE CAUSE OF FAULT CODE 51 HAS BEEN LOCATED AND REPAIRED.
IF A SHORT-TO-GROUND HAS NOT BEEN LOCATED AND REPAIRED, THE SHORT IS INTERMITTENT AND IS NOT PRESENT AT
THIS TIME. INSTALLING A NEW DIAGNOSTIC MONITOR WITH AN INTERMITTENT SHORT IN THE SYSTEM WILL RESULT IN
REPEAT OPEN THERMAL FUSES IN DIAGNOSTIC MONITORS AND REPEAT SERVICE.
