Speedometer Head: Description and Operation
SPEEDOMETER
The instrument panel cluster (IPC) displays vehicle speed as determined by the powertrain control module (PCM). The IPC receives a class 2 message
from the PCM. The IPC uses the vehicle speed sensor (VSS) data received from the PCM and a software program to determine the proper vehicle speed
to display.
