B1935 — Airbag Passenger Inflator Circuit Resistance Low on Squib

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B1935

B1935 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1935 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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.

B1935 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 Restraint Control Module (RCM) continuously measures the resistance of the passenger airbag squib circuit to verify that the deployment loop is within the manufacturer specified range, typically a few ohms total. DTC B1935 sets when the measured resistance falls below the lower threshold, indicating either a partial short within the circuit, a short between the two squib wires, or contamination at the connector causing the resistance to read low. The passenger squib loop runs directly from the RCM through the dash harness to the passenger airbag module above the glove box, so the fault can...
