[SOLVED] U0198 Code: How To Fix Lost Communication With Telematic Control Module

The automobile fault code U0198 indicates a problem with the Telematic Control Module (TCM). The most common symptom is the illumination of the engine light 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.

The importance of repairing this issue lies in the fact that the TCM is responsible for various functions, including communication with other modules in the vehicle. The difficulty of repairing this issue is moderate, with a repair time of 1.0.

To fix this 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 essential to interpret the fault code correctly to ensure the proper repair of the vehicle.Repair Importance Level10.0 (Out of 10)Estimated Repair TimeApproximately 1.0 hourRepair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of u0198 fault code. Here are the symptoms to look out for:

The automobile fault code U0198 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the U0198 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U0198 code is a Controller Area Network (CAN) fault code. CAN is a vehicle bus standard that connects automotive devices without a host computer. CAN bus uses two dedicated wires for communication: CAN high and CAN low.

The U0198 code sets when a periodic message from the Telematic Control Module has not been received.

This fault code indicates a lost communication with the Telematic Control Module.

If your engine light is on and you’re seeing the u0198 fault code, it could be due to a faulty Telematic Control Module, an open or shorted Telematic Control Module harness, or a poor electrical connection in the Telematic Control Module circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

If you’re experiencing an engine light or service engine soon warning light with a U0198 fault code, it could be due to a faulty Telematic Control Module or an open or shorted harness. To fix this issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This will help you identify any poor electrical connections and get your vehicle back on track.

If you’re dealing with a u0198 fault code, keep an eye out for the engine light turning on. The cause of this issue could be a faulty Telematic Control Module, an open or shorted Telematic Control Module harness, or a poor electrical connection in the Telematic Control Module circuit. To fix this problem, check the possible causes listed above and visually inspect the related wiring harness and connectors. Be sure to look for signs of damaged components or broken, bent, pushed out, or corroded connector’s pins.
