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.
PCM turns on SERVICE VEHICLE SOON light and enables fuel injection on future ignition cycles without regard for PASS-KEY fuel enable input status.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- If engine will crank, problem has been isolated to PASS-KEY module, PCM or fuel enable circuit. If engine will not crank, problem is in PASS-KEY system.
- Checking voltage input to PCM will identify if PCM is at fault. Typical signal will be about 2.5 volts.
- Voltage is too low. Possible faulty PASS-KEY module, poor connection at PCM or short to ground in fuel enable circuit.
- Voltage is too high. Possible faulty PASS-KEY module, poor connection at PASS-KEY module or short to voltage or open in fuel enable circuit.
