Speedometer Module


When ignition switch is turned from OFF to RUN position, the electronic display will prove out by momentarily lighting all the display segments and then momentarily turning all displays off. This prove out ensures that all display segments are operational. After prove out, normal speedometer operation begins.
The odometer will display miles or kilometers when the English Metric button is pressed. The Trip Reset button zeros the trip odometer, only when trip odometer is displayed.
The regular odometer displays even digits with last digit in tenths (000000.0 to 199999.9). When 199999.9 is exceeded, the display will change to 100000.0. The trip odometer displays four digits with last digit in tenths (0.0 to 999.9). When 999.9 is exceeded, the display will change back to 0.0.
If replacement of modules are necessary, they are programmed to display a S in the upper right hand corner of speedometer display. Previously accumulated mileage is recorded on a sticker and is placed on the door jamb.
