Probe V6-153 2.5L DOHC (1994)
The diagnostic monitor measures the voltages at the diagnostic monitor connector pins. The diagnostic monitor will sense a short-to-ground on any air
bag deployment circuit and if a short is detected, will open the diagnostic monitor's internal thermal fuse. With the fuse open it removes all power from
the air bag deployment circuits. While the short-to-ground exists, the monitor will flash Fault Code 13. If the short-to-ground is intermittent and
temporarily corrects itself, the diagnostic monitor will flash Fault Code 51. Refer to Figures 6 and 7.
If the short-to-ground returns, the higher priority Code 13 will be flashed instead of 51.
If the air bag indicator is flashing Code 51 and a short-to-ground has not been serviced, this means an intermittent short-to-ground exists in the air bag
system. The diagnostic monitor should only be replaced after service of the short-to-ground has been completed.
Code 51 Sequence of Events
