1. What does U11E3 mean?

U11E3 is documented as “TCM Lost communication with ESM on D-PT CAN.” The supplied official manufacturer-communication evidence also references U0103, “Lost communication with Electric Gear Shift Module.”

2. Technical explanation

The verified evidence identifies a communication concern between the Transmission Control Module (TCM) and the Electric Gear Shift Module (ESM) on the D-PT CAN network. The evidence directs inspection of wiring between the ESM and TCM, voltage checking, and inspection of the ESM pin header for bent pins. It further states that, if wiring and voltage are good and U11E3 and U0103 remain present, the codes are to be erased; the supplied excerpt ends at that point, so any further procedure is not established by verified evidence.

3. What system is affected?

Transmission Control Module (TCM), Electric Gear Shift Module (ESM), and D-PT CAN communication network.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Not yet established by verified evidence.

6. Possible causes

  • A communication issue between the TCM and ESM on the D-PT CAN network is established by the U11E3 description.
  • Wiring between the ESM and TCM is identified for inspection in the official manufacturer communication.
  • Voltage is identified for checking in the official manufacturer communication.
  • Bent pins at the ESM pin header are identified for inspection in the official manufacturer communication.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a qualified service provider.
  • Provide the stored U11E3 code and any accompanying U0103 code to the service provider.
  • Do not attempt high-voltage repairs; no high-voltage repair procedure is provided by the verified evidence.

10. Step-by-step troubleshooting

  1. The official manufacturer communication instructs checking wiring between the ESM and TCM and checking voltage.
  2. The official manufacturer communication instructs checking the ESM pin header for bent pins.
  3. If wiring and voltage are good and U11E3 and U0103 remain present, the supplied excerpt states to erase the DTCs, but does not include the remainder of the procedure.

11. When to contact service

Service need is not explicitly established by the supplied diagnostic record. However, the verified manufacturer communication specifies electrical and connector checks, which should be performed by qualified service personnel.

12. What the service center may check

  • Inspect wiring between the ESM and TCM.
  • Check voltage as directed by the manufacturer communication.
  • Inspect the ESM pin header for bent pins.
  • If wiring and voltage are good and U11E3 and U0103 are still present, erase the DTCs as stated in the supplied excerpt.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied official communication excerpt does not provide a complete repair outcome or final resolution.
