Odometer: Description and Operation
With the ignition switch in ON (II) or START (III), the odo/trip meter driver and speedometer driver in the gauge assembly are supplied battery voltage
through fuse 15. The odometer and speedometer drive circuits receive pulses from the Vehicle Speed Sensor (VSS). The pulse rate increases as the car
accelerates. The frequency and duration of these input pulses are measured and displayed by the speedometer, odometer and tripmeter.
