U11D9 FIAT Meaning

This diagnostic checks the availability of the engine off time 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 sends a SNA default value to the Transmission Control Module (TCM). If the TCM reads this value then the Diagnostic Trouble Code (DTC) U11D9 is set.
