Speedometer

The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to 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 illuminates.

On vehicles equipped W/UY9 the speedometer display configuration can be changed by using the DSPL MODE button. The speedometer can be configured in the following formats:
^ Analog display only
^ Analog and digital displays
^ Digital display only
