Pcm Code E058, Pass Key Control Problem: Action

PCM turns on SERVICE VEHICLE SOON message and will enable fuel injection on future ignition cycles without regard for pass key fuel enable input status.

1. If engine will crank, problem has been isolated to pass key module, PCM or fuel enable circuit. If engine will not crank, perform pass key system diagnosis. See PASS KEY DIAGNOSIS  .
2. Checking voltage to PCM will identify if PCM is at fault. Typical signal will be about 2.5 volts.
3. Voltage too low; problem could be a faulty pass key module, poor connection at PCM or a short to ground in fuel enable circuit.
4. Voltage too high; problem could be a faulty pass key module, poor connection at pass key module, short to voltage or an open in fuel enable circuit.
