Table of contents
U145D JEEP Possible Causes
- Faulty Transmission Control Module (TCM)
- Transmission Control Module harness is open or shorted
- Transmission Control Module circuit poor electrical connection
How do I fix code U145D JEEP?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the U145D JEEP code
The cost of diagnosing the U145D JEEP code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
U145D JEEP Description
Sensor information and other calculated data that is processed by an Electronic Control Module (ECU) can be transmitted over the Controller Area Network (CAN). Some ECUs require information from other ECUs to check the validity of the information relative to that system. In some cases that information is used in the calculations relative to that ECU.
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.
