B1927 definition

A B1927 trouble code is related to a vehicle’s passenger side supplemental restraint system (SRS) and the air bag.

What the B1927 code means

B1927 is a manufacturer specific OBD-II body code for a fault within the passenger side air bag system. When this code is triggered, the passenger side air bag will typically be disarmed by the air bag diagnostic monitor.

What causes the B1927 code?

The most common causes for a B1927 are:

  • Faulty battery connection
  • Faulty wiring to the passenger air bag
  • Faulty grounds
  • Faulty charging system
  • Faulty air bag

What are the symptoms of the B1927 code?

There will be no noticeable symptoms other than a check engine light and perhaps, an air bag light on the gauge cluster. As with most SRS trouble codes, a B1927 will likely disarm the air bags.

How does a mechanic diagnose the B1927 code?

Because a B1927 may be an intermittent issue caused by improper installation of a battery or previous wiring harness repairs, your mechanic will typically first clear the code and reset the vehicle’s engine computer. After this, they will test the vehicle to ensure it can run a number of self-tests at startup. This will help determine if there is a more serious problem as proper installation of a battery (tightening leads, repairing frayed wires, etc.) can fix a B1927 code.

If the code returns after all of this, your mechanic will then inspect the wiring to the passenger side air bag, repairing as necessary. While inspecting, they will ensure all grounds are cleaned and in working condition. They will also inspect the condition of the ignitor and test to ensure the vehicle’s charging system is working properly.

Common mistakes when diagnosing the B1927 code

It is important to try simple fixes first, such as resetting the engine computer or resecuring the battery before testing for a wiring issue within the supplemental restraint system (SRS).

How serious is the B1927 code?

Any air bag code will likely disarm the SRS itself, making it important to fix a B1927 as quickly as possible so your air bag will be functional in the event of an accident.

What repairs can fix the B1927 code?

The most common repairs for a B1927 are as follows:

Additional comments for consideration regarding the B1927 code

A B1927 code should be specific to a Ford, Lincoln, Mercury or Mazda vehicle. It’s wise to look for any recalls that may be tied to a B1927 code as well, meaning the repair could be covered by the manufacturer.

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 B1927.
