About B2184

B2184 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2184 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B2184 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Body Control Module (BCM) reads the front wiper select switch position by monitoring discrete switched inputs that correspond to each stalk position, with the W input representing the Wash request from the washer push button on the wiper stalk. DTC B2184 sets when the BCM detects that the W select signal is held at ground potential when no wash request should be active, indicating a short to ground on that circuit. Because the input normally rests at a pulled up reference and only goes low when the wash button is pressed, a constant ground bias tells the module the input is stuck. When thi...
