[SOLVED] U135D Code: How To Fix Lost Communication With Transmission Control Module

The automobile fault code U135D 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.

It is crucial to check the possible causes listed above to interpret the fault code correctly.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u135d fault code.

Here are the symptoms to look out for:

  • The automobile fault code U135D has the following symptoms: Engine Light ON, Service Engine Soon Warning Light.

The automobile fault code u135d can be caused by a faulty Transmission Control Module, open or shorted harness, or poor electrical connection.

  • The automobile fault code u135d can be caused by a faulty Transmission Control Module.
  • It can also be caused by an open or shorted Transmission Control Module harness.
  • Additionally, a poor electrical connection in the Transmission Control Module circuit can also trigger this fault code.

To fix the u135d automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code u135d, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U135D 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 U135D will range between $75 and $150, depending on the repair time required.

The U135D code is related to the Local Interconnect Network (LIN) Bus. It occurs when there is a loss of serial data communication between the Transmission Control Module and the Chassis Control Module on LIN Bus 2. This code is set when a supervised periodic message that includes the transmitter device availability has not been received.

If this fault code appears, it means that the master control module has detected a problem with the communication between the two modules and has set a no communication code against the non-communicating LIN device. It is important to address this issue promptly to ensure proper communication between the modules and prevent any potential safety hazards.

What are the possible causes of the u135d automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u135d fault code. This code is usually caused by a faulty transmission control module, an open or shorted transmission control module harness, or a poor electrical connection in the transmission control module 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 u135d fault code?

If you’re experiencing the u135d fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few things you can do to fix it. The cause of this issue could be a faulty transmission control module, an open or shorted transmission control module harness, or a poor electrical connection in the transmission control module circuit. To fix this, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the u135d fault code and not fixing it in time?

Ignoring the u135d fault code, which indicates a faulty Transmission Control Module or poor electrical connection, can lead to serious consequences. The engine light will remain on, indicating a problem, and the vehicle may experience transmission issues. It is important to visually inspect the related wiring harness and connectors and check for damaged components to avoid further damage.
