A B1926 trouble code is related to a vehicle’s air bag pressure switch that will turn the passenger side supplemental restraint system (SRS) off and on depending on whether or not a person is sitting in the passenger seat.
B1926 is a manufacturer specific OBD-II body code for a circuit failure for the passenger-side air bag pressure switch. This consists of a pressure sensor, typically mounted underneath the passenger seat, and wiring to connect the sensor to the air bag diagnostic monitor. When a failure is detected during the system’s start-up test, it will trigger a B1926 and likely disarm the passenger side air bag.
The most common causes for a B1926 are:
Symptoms should go unnoticed other than a check engine light and or air bag light on the dash. In the event of an accident, chances are high the passenger air bag will not deploy.
Using a digital volt meter, your mechanic will test the passenger side air bag pressure sensor before determining it needs to be replaced. While chances are high a new sensor will fix the issue, your mechanic may need to continue testing the air bag diagnostic monitor circuit for any damaged wiring or grounds.
Some B1926 codes can be caused by intermittent wiring faults instead of the pressure switch itself. This makes simple tests of the air bag circuit cost effective.
If a B1926 is present, chances are high your passenger air bag will be disabled. This makes repairs important to ensure the safety of occupants.
The most common repairs for a B1926 are as follows:
A B1926 is specific to Ford, Mercury, Lincoln, and Mazda vehicles. Any work that needs to be conducted on a vehicle’s SRS should be handled by a trained professional. The air bag could unexpectedly deploy while working to fix a B1926
