Code B1930 Description
The B1930 diagnostic trouble code indicates a problem with the airbag safing sensor output circuit, specifically a short to ground. The airbag safing sensor is a critical component of the vehicle's supplemental restraint system (SRS), responsible for detecting sudden deceleration or impact and triggering the deployment of the airbags to protect occupants in the event of a collision.
Common Causes of B1930
- Wiring issues: Damaged, frayed, or corroded wiring in the airbag safing sensor output circuit can lead to a short to ground.
- Faulty airbag safing sensor: A malfunctioning or damaged airbag safing sensor itself can cause the output circuit to short to ground.
- Impact or collision: A previous impact or collision that damaged the airbag system components could trigger this code.
- Water damage: Water intrusion into the airbag system components, such as the safing sensor, can cause electrical shorts.
- Poor connections: Loose or poor connections in the airbag system wiring can also lead to a short to ground.
Symptoms of B1930
- Airbag warning light on the dashboard: One of the most common symptoms of a faulty airbag system is the illumination of the airbag warning light on the instrument panel.
- Non-deployment of airbags: In the event of a collision, the airbags may fail to deploy or deploy late due to the malfunctioning airbag safing sensor.
- Diagnostic trouble codes: The vehicle's onboard computer may store additional diagnostic trouble codes related to the airbag system failure.
- Intermittent airbag deployment: The airbags may deploy unpredictably or intermittently, posing a safety risk to occupants.
How to Fix B1930
- Diagnose the issue: Use a diagnostic scanner to retrieve the specific trouble code and identify the exact location of the short to ground in the airbag safing sensor output circuit.
- Inspect wiring and connections: Check the wiring harness, connectors, and terminals for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test the airbag safing sensor: Test the airbag safing sensor using a multimeter to check for proper functionality. Replace the sensor if faulty.
- Clear trouble codes: Once the repair is completed, clear the trouble codes from the vehicle's onboard computer using a diagnostic scanner.
- Perform a system test: Conduct a thorough system test to ensure that the airbag system is functioning correctly and that the airbags deploy as intended.
Cost to Fix B1930
The cost estimate for repairing a B1930 diagnostic trouble code related to an airbag safing sensor output circuit short to ground can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of parts for replacing a faulty airbag safing sensor can range from $100 to $300, while the labor cost for diagnosis and repair can range from $150 to $400. Overall, the total repair cost for this issue could range from $250 to $700, including parts and labor. It's important to note that labor rates and parts prices may vary depending on the location, vehicle make and model, and the auto repair shop chosen. It's recommended to consult with a trusted mechanic or repair shop for a more accurate cost estimate based on your specific situation.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
