Note On Intermittents

WARNING: This page is about a different car, the 1992 Cadillac Fleetwood and 1992 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

If Code E58 is set intermittently, problem could be caused by:

Intermittent short to ground or voltage on circuit No. 229.
Intermittent open on circuit No. 229.
Intermittent loss of power or ground to PASS-KEY module. PASS-KEY module reads ignition key once each ignition cycle when ignition is first turned on. Faults in key pellet and circuits can cause a no-start condition, but they cannot cause a stall or set a Code E58.
