About B2235

B2235 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 B2235 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 B2235 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 B2235 is set by the Supplemental Restraint System (SRS) control module when it detects a general fault in the passenger airbag inflator (squib) circuit. This is a generic passenger airbag circuit code that can be triggered by an open circuit, a short to ground, a short to power, or a resistance value that is out of the allowable range on the passenger airbag igniter loop. The SRS module continuously monitors the resistance across the passenger airbag squib by passing a small diagnostic current and measuring the resulting voltage drop, and any reading outside specification sets this code.
