U145D Jeep Code - Implausible Data Received From TCM On D-PT
Quick Answer
Sensor information and other calculated data that is processed by an Electronic Control Module (ECU) can be transmitted over the Controller Area Network (CAN). Common causes include Faulty Transmission Control Module (TCM), Transmission Control Module harness is open or shorted, Transmission Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U145D Jeep Description
If the transmitting ECU knows that the data is not valid, it will transmit a CAN message indicating that the information is not valid or not available. Often, this message is known as a Signal Not Available (SNA) message.
When a SNA message is transmitted, a Diagnostic Trouble Code (DTC) will be set in the receiving ECU.
If a SNA message is received, this indicates that the transmitting ECU cannot transmit good data relative to the information that it was supposed to send. Typically, the transmitting ECU will also have a DTC set related to that information. Therefore, in most cases, this DTC is considered informational because the error is related to another ECU.
The DTC will set if the ESM detects an invalid Controller Area Network (CAN) BUS signal from the TCM.
What are the Possible Causes of the DTC U145D Jeep?
- Faulty Transmission Control Module (TCM)
- Transmission Control Module harness is open or shorted
- Transmission Control Module circuit poor electrical connection
