The Gauge Drive Circuit Check
When entering the self-diagnostic mode, the fuel gauge and the engine coolant temperature gauge sweep from the minimum position to the maximum position, then return to the minimum position.
NOTE: After the beeper stops sounding and the gauge needles return to the minimum position, pushing the SEL/RESET knob starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again. The check cannot be started again until the gauge needles return to the minimum position.
