Speedometer Head: Description and Operation
SPEEDOMETER
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM)/powertrain control module (PCM).
The ECM/PCM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The IPC uses the vehicle speed signal circuit (4,000
pulses/mile), class 2 message from the ECM/PCM in order to calculate the vehicle speed. If the IPC detects a malfunction in the vehicle speed signal
circuit from the ECM/PCM, the IPC uses the class 2 message from the EBCM, indicating the vehicle speed as a backup. If the speedometer reaches (108
mph) the fuel will shut-off, and it will turn back ON when the speedometer is at (106 mph). The speedometer displays either miles or kilometers as
requested by the activation of the english/metric button on the driver information center (DIC). The associated indicator (km/h or mph) illuminates.
