About B2336

B2336 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 B2336 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 B2336 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

DTC B2336 indicates that the body control module or door module has detected an electrical fault in the exterior mirror switch assembly circuit. The mirror switch is a multi function rotary or rocker style switch mounted on the driver door trim or centre console that allows the driver to select which mirror to adjust and then drive the mirror motors in four directions through resistor ladder or discrete inputs to the controlling module. A circuit failure code sets when the module detects an input voltage outside its expected pattern, including stuck switch inputs, shorted contacts, or open swi...
