Code B1914 Description
The B1914 diagnostic trouble code indicates that there is a circuit short to ground in the Air Bag Crash Sensors 1/2. Air bag crash sensors are crucial components of a vehicle's safety system that are designed to detect sudden deceleration in the event of a collision and trigger the deployment of the airbags to protect the occupants. When this code is triggered, it means that there is an electrical issue in the circuit that connects the crash sensors to the airbag system, causing a short to ground.
Common Causes of B1914
- Damaged wiring harness leading to the airbag crash sensors
- Faulty airbag crash sensor
- Loose or corroded electrical connections in the airbag system
- Malfunctioning airbag control module
- Physical damage to the airbag crash sensors due to a previous collision or impact
Symptoms of B1914
- Airbag warning light illuminated on the dashboard
- Inability to pass a vehicle inspection due to airbag system malfunction
- Fault codes related to the airbag system stored in the vehicle's computer
- Loss of power to the airbag system
How to Fix B1914
- Diagnose the issue using a scan tool to read the fault codes and pinpoint the location of the circuit short to ground.
- Inspect the wiring harness and connections for any signs of damage, corrosion, or looseness.
- Test the airbag crash sensors for proper functionality and replace any faulty sensors.
- Check the airbag control module for defects and replace if necessary.
- Clear the fault codes from the vehicle's computer and perform a test to ensure that the airbag system is functioning correctly.
Cost to Fix B1914
The cost of repairing a circuit short to ground in the Air Bag Crash Sensors 1/2 can vary depending on the extent of the damage and the specific components that need to be replaced.

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.
