[SOLVED] Fixing U11C8: Engine Coolant Temperature Message Lost

The automobile fault code U11C8 indicates a problem with the Transmission Control Module (TCM).

The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty TCM, an open or shorted TCM harness, or a poor electrical connection in the TCM circuit. It is important to address this issue promptly as it can lead to transmission problems. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

The automobile fault code U11C8 has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of U11C8 will be between $75 and $150, depending on the repair time required.

The U11C8 fault code is related to the Engine Coolant Temperature (ECT) signal.

It determines the availability of the ECT signal sent by the PCM via a CAN message. If the TCM reads the Signal Not Available (SNA) default value, then the U11C8 DTC is set. This code indicates a lost engine coolant temperature message.

What are the possible causes of the u11c8 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u11c8 fault code. This code is usually caused by a faulty Transmission Control Module (TCM), an open or shorted TCM harness, or poor electrical connection in the TCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the u11c8 fault code?

If you’re experiencing the u11c8 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Transmission Control Module (TCM), an open or shorted TCM harness, or a poor electrical connection in the TCM circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the u11c8 fault code and not fixing it in time?
