About B1161

B1161 is a manufacturer-specific body diagnostic trouble code recorded for Nissan vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1161 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.

B1161 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 Supplemental Restraint System (SRS) Control Module continuously monitors the right hand curtain shield airbag squib circuit for correct continuity and low resistance. The squib is the electric initiator that fires the curtain airbag in a side impact or rollover event, and the SRS module expects a tightly controlled resistance (typically in the 2 to 5 ohm range on Nissan) with no applied voltage when the circuit is dormant. DTC B1161 is logged when the SRS module detects an open circuit, excessive resistance, or a short to battery on the RH curtain squib line during its self test or during ...
