About B0110

B0110 is a generic (obd-ii standard) body diagnostic trouble code recorded for Toyota vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B0110 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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 B0110 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 B0110:43 is a Toyota body code that sets when the airbag sensor assembly, also called the SRS ECU, detects a short circuit in the right hand (RH) side airbag squib circuit. The squib is the electrically fired igniter in the RH side or curtain airbag, and the SRS ECU continuously monitors its firing loop for correct resistance and for any short to ground or to power. Toyota most often classes this fault as the two squib wires shorted together or a conductor shorted to the vehicle, commonly caused by a chafed harness or contamination in a connector. When B0110:43 is set the airbag warning la...
