Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Inspect instrument cluster printed circuit for contamination or damage. If instrument cluster printed circuit is faulty, replace instrument cluster printed circuit. See PRINTED CIRCUIT under REMOVAL & INSTALLATION. If printed circuit is okay, replace fuel gauge and fuel gauge indicator module. See FUEL GAUGE/TEMPERATURE GAUGE under REMOVAL & INSTALLATION. After repair, test system for normal operation.
