Code U11D7 Description

This diagnostic checks for the availability of the Electronic Stability Program (ESP) Requested Shift Schedule signal which is sent by the ESP via a Controller Area Network (CAN) message. The diagnostic checks the signal availability by checking if the received value is not equal to the Signal Not Available (SNA) default value. When the signal is not available, the ESP sends an SNA default value to the Transmission Control Module (TCM). If the TCM reads this value then the Diagnostic Trouble Code (DTC) U11D7 is set.
