Pinpoint Test At : U0100:00: Notes
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 Diagnostic Trouble Codes (DTCs) and may also exhibit system function concerns.
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 powertrain data messages received from the PCM through the BCM over the MS-CAN are missing for longer than 2 seconds. |
