Code U11DA Chrysler Description

This diagnostic checks the availability of the brake torque level signal which is sent by the Anti-lock Braking System (ABS) Module via a Controller Area Network (CAN) message. The diagnostic checks the availability by checking the valid bit. When the signal is not available, the ABS 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.
