Programmable Speedometer/Odometer Module (PSOM)

The programmable electric analog speedometer receives its input from the anti-lock brake sensor except on F-Super Duty Motorhome where it receives its input from the parking brake-mounted speed sensor.

The liquid crystal display (LCD) odometer is a combination trip odometer and total odometer. The total odometer is normally displayed. To see the trip odometer, press and release the SELECT button on the upper right side of the speedometer. To zero out the trip odometer, press and release the RESET button on the upper left side of the speedometer while the trip odometer is displayed. If the trip odometer is displayed, press and release the SELECT button to return the display to the total odometer value. The speedometer, containing the trip odometer and total mileage odometer, is serviceable only as an assembly.
