K 1500 Yukon Denali AWD V8-6.0L VIN U (2002)
Shift Indicator: Description and Operation
The IPC displays the vehicle speed based on the vehicle speed signal 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
km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.
