About B2183

B2183 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 B2183 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 B2183 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 a set of discrete switched inputs that correspond to the different wiper positions, with the H input typically representing the High speed position. DTC B2183 sets when the BCM detects that the H select signal is held at ground potential when no valid command should be present, indicating a short to ground on that circuit. Because the input normally sees a pull up reference and only goes low when the switch contact closes in the High position, a constant ground bias tells the BCM the input is stuck. When t...
