[SOLVED] Fix U1886 Code: Engine Control Module Communication Lost

The automobile fault code U1886 indicates a problem with the Engine Control Module (ECM) or the Battery Energy 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, an open or shorted ECM harness, a poor electrical connection in the ECM circuit, or a faulty Battery Energy Control Module. The importance of repairing this fault code 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’s 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 accordingly.

The fault code U1886 is a communication error between the steering column control module and the instrument cluster. 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 U1886 fault code can range from $75 to $150.

The U1886 fault code is related to the loss of communication between the Battery Energy Control Module and the Engine Control Module. This fault code is triggered when the Battery Energy Control Module does not receive a periodic serial data message from the Engine Control Module within 3 seconds. The U1886 fault code is used to diagnose communication issues on a high-speed General Motor Local Area Network (GMLAN) bus.

If you encounter this fault code, it is recommended to have your vehicle inspected by a qualified mechanic to identify and fix the underlying issue.
