Decoding U0043: Understanding Your Vehicle’s Abs Wheel Speed Sensor Circuit
The U0043 fault code is related to the Vehicle Communication Bus ‘B’ (-) Low.
This code indicates that there is a problem with the communication between different devices in the vehicle. The Controller Area Network (CAN) is a vehicle bus standard that interconnects automotive devices without a host computer. The CAN bus uses two dedicated wires for communication, 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. The U0043 code sets when a supervised periodic message that includes the transmitter device availability has not been received.
