Fuel Gauge Operation Test
- Remove instrument cluster and disconnect electrical connectors. Connect positive 12 volts to terminal No. A-1. Attach negative lead to terminals No. A-9 and A-20. Connect jumper wire between terminals No. A-4 and A-10. All segments on fuel gauge should illuminate for 130 seconds, then go out. Disconnect fuel tank sending unit connector. All segments should illuminate and fuel level warning light should flash.
- If operation is not as described, replace wire harness or replace computer. If okay, and fuel gauge still does not work, replace fuel gauge. See Fig 1.
