Fuel Gauge Indicates Full At All Times (Dual Tanks)
- Disconnect instrument cluster connector. Install a fused jumper wire between instrument cluster connector terminal No. 31 (Black wire) and ground. See Figure . Install another fused jumper wire between instrument cluster connector terminal No. 22 (Pink wire) and voltage. Install another fused jumper wire between instrument cluster connector terminal No. 16 (Purple wire) and ground. If fuel gauge indicates full, replace instrument cluster connector. If fuel gauge does not indicate full, go to next step.
- Remove fused jumper wires from instrument cluster connector. Reconnect instrument cluster connector. Disconnect fuel pump balance module connector. Connect fused jumper wire between fuel pump balance module connector terminal "F" (Purple wire) and ground. If fuel gauge indicates full, repair open circuit in Purple wire. If fuel gauge indicates empty, reconnect fuel pump balance module connector. Go to FUEL GAUGE INACCURATE (DUAL TANKS) test.
