About B2224

B2224 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 B2224 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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 B2224 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 or passenger door module monitors the power mirror drive circuits to detect faults in the mirror motors that adjust the passenger side glass in the horizontal and vertical axes. DTC B2224 sets when the module detects a circuit fault on the passenger mirror drive output, such as an open circuit, a short to ground, a short to power, or a stalled motor that fails to draw the expected current. The mirror motors are reversible DC motors commanded by internal H bridge drivers that switch polarity to move the glass, and each drive output is monitored for the expected current s...
