About B2222

B2222 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 B2222 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 Window Control Module monitors the current draw of the passenger rear power window motor during operation. DTC B2222 sets when the measured motor current exceeds the calibrated upper threshold for the rear window circuit, indicating excessive mechanical resistance or an electrical fault that increases motor load. The current feedback is part of the anti pinch and obstruction detection logic, so any condition that increases mechanical drag, such as binding glass, frozen channels, a damaged regulator, or worn motor brushes, will register as overcurrent. When this code is set, one touch opera...
