About B2206

B2206 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.

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 B2206 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 B2206 code indicates that the gyroscope sensor inside the navigation module has reported an internal error or has returned implausible data. The gyroscope, also called a yaw rate sensor in this context, measures the rate of vehicle rotation around the vertical axis and is a core input to the dead reckoning function that maintains an accurate vehicle position when GPS signal is briefly lost, for example inside tunnels, in underground parking, or among tall buildings. The code is set when the gyroscope fails its internal self test, returns a stuck value, or returns values outside the plausib...
