If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative tachometer, temperature gauge or odometer.
Normal Operation and Fault Conditions
If the IPC does not receive the vehicle speed data from the PCM for more than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the speedometer to 0 km/h (0 mph). If the vehicle speed data received is deemed invalid by the IPC for 5 seconds or more, the IPC sets DTC U0401:00 and defaults the speedometer to 0 km/h (0 mph).
