[SOLVED] U2626 Code: How To Fix Lost Communication Between Modules

The automobile fault code U2626 indicates a problem with the Engine Control Module (ECM) or Reductant Control Module.

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 ECM, open or shorted ECM harness, poor electrical connection in the ECM circuit, or a faulty Reductant Control Module. The importance of repairing this issue lies in the fact that it can affect the performance of the vehicle and lead to further damage. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector pins.

The repair time is estimated to be around 1.0 hour. It is essential to interpret the fault code correctly to identify the root cause of the problem and fix it effectively.

The fault code U2626 is a communication error between the ABS module and the PCM.

The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code is dependent on the hourly rate charged by the auto repair shop.

The average hourly rate charged by most auto repair shops is between $75 and $150.

Therefore, the cost of fixing the U2626 fault code can range from $75 to $150.

The U2626 code is related to the communication between the Reductant Control Module and the Engine Control Module.

This fault code indicates that the Reductant Control Module has lost communication with the Engine Control Module on the Powertrain Sensor CAN Bus. The Diagnostic Trouble Code (DTC) will set when a supervised periodic message that includes the transmitter device availability has not been received. This fault code can cause issues with the vehicle’s emissions system and should be addressed promptly to avoid further damage.

What are the possible causes of the u2626 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u2626 fault code. This code is caused by a faulty Engine Control Module (ECM), an open or shorted ECM harness, poor electrical connection in the ECM circuit, or a faulty Reductant Control Module. To fix this issue, inspect the wiring harness and connectors visually, 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 u2626 fault code?

If you’re experiencing the u2626 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. The possible causes include a faulty Engine Control Module (ECM), an open or shorted Engine Control Module harness, a poor electrical connection in the Engine Control Module circuit, or a faulty Reductant Control Module. To address these issues, you should 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 u2626 fault code and not fixing it in time?

Ignoring the u2626 fault code, which indicates a faulty Engine Control Module or Reductant Control Module, can lead to serious consequences. The Engine Light or Service Engine Soon Warning Light will remain ON, indicating a problem with the engine. Ignoring this issue can result in reduced fuel efficiency, engine damage, and even complete engine failure. It is crucial to check the possible causes, visually inspect the wiring harness and connectors, and fix any damaged components to avoid further damage.

u2626 error fault code explained

If your engine light is on, it could be due to a faulty Engine Control Module (ECM), an open or shorted ECM harness, poor electrical connection, or a faulty Reductant Control Module. Visually inspect the wiring harness and connectors for damage or corrosion. Check for broken, bent, or pushed out connector pins.
