Description & Operation: Gauges: Speedometer

Gauge is IPC controlled using VCM/PCM data on Class 2 serial data line. Vehicle Speed Sensor (VSS) produces voltage pulses of frequency proportional to vehicle speed. This signal is processed by PCM/VCM to produce a voltage pulse signal to IPC.

NOTE: Incorrect VSS calibration may adversely affect operation of ABS, engine control system and cruise control system.
