U11C6 Dodge Code - Lost Engine Torque Request Message

Quick Answer

This diagnostic determines the availability of the static indicated engine torque signal, the engine friction torque signal, and the indicated driver torque request signal sent by the Powertrain Control Module (PCM) via two Controller Area Network (CAN) messages. Common causes include Faulty Transmission Control Module (TCM), Transmission Control Module harness is open or shorted, Transmission Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U11C6 Dodge Description

This diagnostic determines the availability of the static indicated engine torque signal, the engine friction torque signal, and the indicated driver torque request signal sent by the Powertrain Control Module (PCM) via two Controller Area Network (CAN) messages. The diagnostic determines the availability by checking the valid bit. When the signals are not available, the PCM sends a Signal Not Available (SNA) default value to the Transmission Control Module (TCM). If the TCM reads this value then the Diagnostic Trouble Code (DTC) U11C6 is set.
