Code U11D5 RAM Description

This diagnostic checks the availability of the driver power request signal which is sent by the Powertrain Control Module (PCM) via a Controller Area Network (CAN) message. The diagnostic checks the availability by checking the received value is not equal to the Signal Not Available (SNA) default value. When the signal is not available, the PCM module sends an SNA default value to the Transmission Control Module (TCM). If the TCM reads this value then the Diagnostic Trouble Code (DTC) U11DA is set.
