Code U0019 Dodge Description

A Controller Area Network (CAN) is a vehicle bus standard designed to interconnect automotive devices without a host computer. Operating information and commands are exchanged among the devices. The devices have programmed information about what messages are needed to be exchanged on the serial data circuits. CAN bus uses two dedicated wires for communication. The wires are called CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V. When data bits are being transmitted, the CAN high line goes to 3.75V, and the CAN low drops to 1.25V, thereby generating a 2.5V differential between the lines. Since communication relies on a voltage differential between the two bus lines, the CAN bus is NOT sensitive to inductive spikes, electrical fields, or other noise. The Diagnostic Trouble Code (DTC) sets when a supervised periodic message that includes the transmitter device availability has not been received.

Discuss the causes and fixes for U0019 Dodge OBDII Code

  • My 2007 Dodge Magnum SRT8 has multiple failures of electrical equipment and 64 ODB codes. It appears that the d55 circuit has an issue.
    Is this circuit fused in any way other than the number three circuit breaker?

    • The D55 circuit in your 2007 Dodge Magnum SRT8 is part of the CAN system, which handles data signals between control modules rather than powering solenoids or motors. It isn't fused beyond the #3 circuit breaker, but issues like multiple codes and equipment failures often stem from CAN communication faults, such as wiring, connectors, or ground issues.

      Possible Solution:
      Inspect the CAN wiring harness and connections for damage or corrosion, especially at common ground points and near the Power Distribution Center (PDC). Ensure the #3 circuit breaker is functioning properly, and test continuity and resistance in the D55 circuit to identify any shorts or open circuits.
