About B2233

B2233 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 B2233 is stored, the module has detected an open (broken or disconnected) electrical path 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 B2233 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 B2233 is set by the Supplemental Restraint System (SRS) control module when it detects an open circuit condition in the passenger airbag igniter Loop #2 conductor. Loop #2 corresponds to the second igniter stage of a dual stage passenger airbag, which the SRS module fires during higher severity crash events to provide a more aggressive deployment. The module continuously monitors the resistance across each igniter circuit by passing a small diagnostic current, and if the measured resistance rises above the allowable threshold, an open circuit is reported. When this code is active, the airb...
