Pinpoint Test AS: DTC U0100:00: Notes

Diagnostic Overview 

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.

Normal Operation and Fault Conditions 

Once the IPC sets DTC U0100:00, multiple gauges or indicators are likely to be inoperative in the IPC. Other modules that require data from the IPC all set communication DTCs and may also exhibit system function concerns.

IPC DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
U0100:00 Lost Communication With ECM/PCM "A": No Sub-Type Information Sets in continuous memory in the IPC if data messages received from the PCM over the HS-CAN are missing for 5 seconds or more.
