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.
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.
The most common causes for a B1925 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 air bag will not deploy.
Many air bag codes can be caused by intermittent voltage or grounding issues caused by weak batteries or bad connections. Your mechanic will first ensure this is not the culprit before moving on to the air bag circuit. They will inspect the wiring from the battery to the passenger side air bag, repairing as necessary. While inspecting, they will ensure all grounds are cleaned and in working condition.
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.
Any air bag code will likely disarm the SRS itself, making it important to fix a B1925 as quickly as possible so your air bag will be functional in the event of an accident.
The most common repairs for a B1925 are as follows:
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 B1925
