U0101-LOST COMMUNICATION WITH TCMDoes that mean that they are still present? Or they were fixed? This are all the codes that were stored when they changed the battery
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
- With the ignition on.
- Battery voltage between 10 and 16 volts.
- Ignition Off Draw (IOD) fuse installed.
- Totally Integrated Power Module (TIPM) is configured correctly.
- Set Condition:
Bus messages not received from the Transmission Control Module (TCM) for approximately 500ms.

For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID.
- When Monitored:
Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN Bus Off Performance DTC present. - Set Condition:
When the TCM detects an incorrect CAN ID from the ABS control module.
