The U184B code indicates a loss of communication with the remote heater and air conditioning control module on the low-speed CAN bus.

The serial data circuit is used by devices in the vehicle to communicate with each other. When a device stops communicating on the serial data circuit, the state of health message it normally sends disappears. Other devices on the serial data circuit detect the absence of the state of health message and set a DTC associated with the loss of the state of health of the non-communicating device.

The U184B code sets when a supervised periodic message that includes the transmitter device availability has not been received.
