Code U11CD Chrysler Description

This diagnostic checks for the availability of both Rear Wheel Speed signals which are sent by the Anti-lock Braking System (ABS) via a Controller Area Network (CAN) message. The Transmission Control Module (TCM) uses this information to calculate the vehicle speed. The diagnostic determines the availability of both Rear Wheel Speed signals by checking the valid bit. When one of the signals is not available, the ABS sends a Signal Not Available (SNA) default value to the TCM. When both signals are equal to SNA default values then the Diagnostic Trouble Code (DTC) U11CD is set.
