B1065 — Passenger Side Airbag Circuit High Resistance

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

About B1065

B1065 is a manufacturer-specific body diagnostic trouble code recorded for Suzuki vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1065 is stored, the module has detected a signal or supply voltage higher 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.

B1065 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 SRS Control Module (SRSCM) on Suzuki vehicles continuously measures the loop resistance of the passenger front airbag squib circuit, which includes the inflator squib inside the passenger airbag module, the harness from the SRSCM up the A pillar and across to the glovebox area, and all intermediate connectors. DTC B1065 sets when this measured loop resistance exceeds the calibrated upper threshold (typically in the region of 3.0 to 3.5 ohms depending on model) but has not yet gone fully open, with ignition ON, SRS armed, battery voltage within range, and the condition present beyond the mo...
