TESTING FUEL GAUGE IN DIAGNOSTIC MODE

Use a jumper wire and connect sender terminals, 1,

and the EIC board will light and beep. If the EIC board

lights and beeps, the EIC and circuit wires to the

sender are OK. If the EIC board fails to light, check

the wires to the EIC board.

If the fuel gauge is not working and the wiring and the

fuel sender are found to be good, the complete EIC

board will require replacement.
