U1844: Unveiling The Mystery Behind Your Car’s Abs System
The U1844 code is related to the serial data circuit in a vehicle.
It indicates that the Battery Energy Control Module has lost communication with the HybridEV Powertrain Control Module on Bus B. This loss of communication can occur due to a power or ground failure.
When a device stops communicating on the serial data circuit, the state of health message it normally sends disappears, and other devices on the circuit detect its absence.
This absence of the state of health message sets a DTC associated with the loss of the state of health of the non-communicating device.
