Intermittent Open/Short Circuit Check
- Wiggle suspected PASS-Key(R) system wiring harness. This will set a fault Code ED58 in PCM if problem is detected in fuel enable circuit. Check for history fault codes in PCM. If a PASS-Key(R) history code is present, check for intermittent wiring or contacts in fuel enable circuit. See G - TEST W/ CODES article in the ENGINE PERFORMANCE Section.
- Check module power and ground circuits while wiggling harness. SECURITY indicator will light and remain on while a problem is detected in key resistance circuits, and will turn off if fault goes away. SECURITY indicator will light for a 5 second bulb check if ground or battery inputs are intermittent. Loss of battery input is not a possibility since internally the decoder module will use ignition input for power if battery is lost.
