U11CB MeaningThis diagnostic checks the availability of the left rear wheel speed signal which is sent by the Electronic Stability Program (ESP) via a Controller Area Network (CAN) message. The diagnostic checks the availability by checking the valid bit. When the signal is not available, the ESP 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) U11CB is set.
