Speedometer and Odometer

Voltage is applied to the speedometer/odometer from the gauge fuse, located in junction block 2, when the ignition is in the ON or START positions. Current flows from the gauge fuse to Junction Block 3, via the RED/BLU wire between the junction block 2, C2 cavity 9 and the junction block 3, C3 cavity 5. Current flows to the instrument cluster assembly C1 cavity 2 from the junction block 3 C2 cavity 18.

The vehicle speed sensor (VSS) is a gear-driven permanent magnet generator housed in the vehicle's transaxle. This sensor generates a sine wave output with a frequency proportional to vehicle speed. This signal has an output that is switched to ground at a frequency of 1 Hz per Mile per hour. This signal drives the speedometer and odometer. The speedometer sends a signal to the PCM and the cruise control system through the PPL/WHT wire spliting at the junction block 3.

The season odometer displays the total accumulated miles of the vehicle. This value is permanently stored in the instrument cluster. When an instrument cluster is replaced the law requires either the odometer reading of the replacement unit be set to register the original mileage or that a label be installed on the driver's door frame to show the previous odometer reading and the date of replacement. Since the mileage can NOT be set on the odometer in this vehicle an odometer label must be used.

The trip odometer displays the accumulated miles to the tenths of a mile since the last reset.
