Code P058, Pass-Key(R) Fuel Enable Problem: Action

WARNING: This page is about a different car, the 1995 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.

"THEFT SYSTEM PROBLEM, CAR MAY NOT RESTART" message is displayed on DIC. Enables fuel injection on future ignition cycles without regard for PASS-Key(R) fuel enable input status.

NOTE: Test numbers refer to numbers on diagnostic chart.

If engine will crank, problem has been isolated to PASS-Key(R) module, PCM or fuel enable circuit. If engine will not crank, perform PASS-Key(R) system diagnosis. See PASS-KEY(R) DIAGNOSIS.
Checking voltage to PCM will identify if PCM is at fault. Typical signal will be about 2-3 volts.
Checks if PCM is recognizing cranking fuel enable signal from PASS-Key(R) decoder module.
Checks circuit No. 229 for short or open circuit. If circuit is okay, check PASS-Key(R) module terminal contacts.
