Troubleshooting Hints

^ Try the following checks before doing "PASS-Key II Diagnostic System Check".

1. Check key pellet sensing contacts in ignition key lock cylinder by looking into key opening. If contacts are damaged, or not silver in color, replace ignition key lock cylinder.

2. Check all ignition keys by using J 35628-A PASS-Key II Interrogator or equivalent. If key code window shows "E," or display is erratic, replace owner's key.

3. Check ignition key for a cracked resistor pellet or a pellet that is dirty or coated. Also check that ignition key is free from excess plastic around resistor pellet contacts.

4. Check I/P Fuse Block PCM fuse by visual inspection.

5. Check Rear Fuse Block PCM/VATS fuse by visual inspection

6. If PASS-Key II system is intermittent, check that PASS-Key II module connector is tight and terminals are clean. Check applicable connectors for proper terminal contact, refer to "Intermittents and Poor Connections" in Diagrams.

7. If starter enable relay must be replaced, also check WHT (6) wiring to the starter solenoid for a possible short. A short may have caused relay to fail.

8. Check Rear Fuse Block I/P 1 fuse by visual inspection. If the I/P 1 fuse is blown, (Oldsmobile only), there is still a battery feed from the HZRD/STOP fuse to the RAC module. Therefor the RAC module may not be completely shut down.
