|U1119 code description

The Transmission Control Module (TCM) receives information from the Engine, Anti-lock Brake System, and the Electronic Gear Shift control modules over the Controlled Area Network (CAN) C bus. The CAN C bus is a high-speed communication bus that allows real-time control capability between various controllers. Most messages are sent every 20 mSec, this means critical information can be shared between multiple controllers almost instantaneously. The CAN C bus is a two-wire bus with a CAN (+) and a CAN (-) circuit. To reduce the potential of radio and other electrical noise interference, the CAN Bus circuit wiring is manufactured using a twisted pair configuration within the electrical wiring harness. The Diagnostic Trouble Code (DTC) will set if a valid CAN ID was not received in the required time from the Front Control Module (FCM).
