air bag code 45 - Left Hand Radiator Primary Crash Sensor Not Mounted To Vehicle Properly air bag code 54 ( just in case ! ) - Intermittent Or Repaired Primary Crash Sensor Circuit Shorted To Ground
It means the primary crash sensor circuit has had a short to ground, possibly an activated crash sensor due to a crash detected, and then the issue has gone away, in other words, it is intermittant. If there has been no crash then there may be an intermittant issue with that crash sensor, or the crash sensor cicuit wiring. The fault code may be cleared to see if the issue returns. The companion code to a 54 is a code 14. When there is a short that occurs, the lamp should flash a 14 at first, then begin flashing the 54 when the short goes away.
