Speedometer
The IPC displays the vehicle speed based on the information received from the Power Control Module (PCM). The PCM converts the data received from the vehicle speed sensor into a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 MPH (0 km/h) if a malfunction in the vehicle speed signal circuit exists.The speedometer displays either miles or kilometers as requested by the activation of the ENG/MET button on the Driver Information Center (DIC). The associated indicator (km/h or MPH) illuminates. The speedometer display configuration can be changed as requested by the activation of the DSPL MODE button on the Driver Information Center (DIC) switch.
The speedometer can be configured in the following formats:
^ Analog display only
^ Analog and digital displays
^ Digital display only
