Decoding U1803: Understanding Your Vehicle’s Abs Communication Fault
The U1803 code indicates a loss of communication with the HybridEV Powertrain Control Module 2. The serial data circuit is responsible for communication between devices in the vehicle.
When a device stops communicating on the serial data circuit, other devices detect its absence and set a DTC associated with the loss of the state of health of the non-communicating device.
A loss of serial data communications DTC does not represent a failure of the devices that contain the stored DTC.
