The Gauge Drive Circuit Check
When entering the self-diagnostic mode, the speedometer, the tachometer, the fuel gauge, and the engine coolant temperature gauge needles sweep from the minimum position to 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 reset switch 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.
If a needle fails to sweep, or the beeper does not sound, replace the gauge control module (see Gauge Control Module Replacement ).
