Code U11C7 Description

This diagnostic determines the availability of the maximum indicated engine torque signal sent by the Powertrain Control Module (PCM) via a Controller Area Network (CAN) message. The diagnostic determines the availability by checking the valid bit. When the signal is 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) U11C7 is set.
