Code B0105 Saturn Description
The B0105 diagnostic trouble code (DTC) for Saturn vehicles indicates a problem with the passenger-side Electronic Front Sensor (EFS) sending an incorrect identification message. The EFS is a crucial component of the vehicle's airbag system, responsible for detecting passengers in the front seat and deploying the airbag accordingly in the event of a collision. When the EFS sends an incorrect identification message, it can lead to the airbag system malfunctioning, potentially putting passengers at risk in the event of an accident.
Common Causes of B0105 Saturn
- Faulty EFS sensor.
- Wiring or connection issues between the EFS and the airbag control module.
- Corrosion or damage to the EFS sensor or wiring.
- Software issues in the airbag control module.
- Electrical interference or signal disruption affecting communication between components.
Symptoms of B0105 Saturn
- Airbag warning light illuminated on the dashboard.
- Inconsistent or erratic airbag deployment.
- Passenger airbag not deploying in a crash.
- Fault codes related to the airbag system stored in the vehicle's computer.
- Loss of communication with the EFS module.
How to Fix B0105 Saturn
- Begin by diagnosing the specific cause of the incorrect identification message, using a scan tool to retrieve the DTC and pinpoint the source of the issue.
- Inspect the wiring and connections between the EFS sensor and the airbag control module for any damage, corrosion, or loose connections. Repair or replace any faulty wiring or connectors.
- Test the EFS sensor to ensure it is functioning correctly. Replace the sensor if necessary.
- Clear the DTC from the vehicle's computer and perform a test to verify that the issue has been resolved.
- If the problem persists, further diagnosis may be required to identify any underlying software or communication issues within the airbag system.

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.
