About B1134

B1134 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1134 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.

B1134 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The airbag control module, also called the SRS module or SDM, continuously monitors the firing circuit for the front left side airbag through a low current diagnostic loop. DTC B1134 sets when the module measures resistance above the expected squib value, indicating an electrical open somewhere between the module and the front left side airbag inflator. Common points of failure are the seat mounted or door mounted airbag connector, the yellow SRS connectors with their shorting bars, and any clock spring or seat harness the circuit passes through. When this code is stored the module disables th...
