B1925 definition

A B1925 trouble code is related to a vehicle’s supplemental restraint system (SRS) and its connection between the battery and the passenger side air bag.

What the B1925 code means

B1925 is an OBD-II body code for a Ford vehicle, as all B1xxx codes are manufacturer specific. It pertains to a vehicle’s electrical circuit for the battery and the passenger side air bag. When the air bag circuit monitor conducts its self-test at start up, a B1925 will be triggered if a voltage or resistance issues is detected.

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 air bag will not deploy.

How does a mechanic diagnose the B1925 code?

Many air bag codes can be caused by intermittent voltage or grounding issues caused by weak batteries or bad connections.

While inspecting, they will ensure all grounds are cleaned and in working condition.

Common mistakes when diagnosing the B1925 code

Before digging into the air bag circuit wiring, it’s wise to ensure there isn’t a battery or charging system fault causing a B1925 instead.
