Driving with a B103E code is not advisable, as it suggests that your airbag system may not function correctly in a collision. It's best to have the issue examined before continuing to use the vehicle.
How can I diagnose B103E myself using GeekOBD APP?
Using the GeekOBD APP, connect your device to the OBD2 port, perform a full scan, and check for codes and freeze-frame data related to B103E. Analyze the data for insights into possible repairs.
What vehicles are most commonly affected by B103E?
The B103E code frequently occurs in 2015-2020 Ford F-150 and Chevrolet Silverado models. Always check for any recalls or Technical Service Bulletins (TSBs) that may address this issue.
How can I prevent B103E from happening again?
Regular maintenance checks, protecting wiring from moisture, and ensuring proper installation of components can help prevent the recurrence of B103E. It's also wise to have diagnostics performed periodically.
What is B103E?
The B103E diagnostic trouble code (DTC) indicates a fault related to the airbag system, specifically involving the side impact sensor. This code is often triggered when the vehicle's onboard diagnostic system detects an issue with the sensor's performance or its connection to the airbag control module. For many drivers, this means that the airbag system may not deploy in the event of an accident, posing a serious safety risk. Common in vehicles such as the 2015-2020 Ford F-150 and Chevrolet Silverado, the B103E code usually stems from wiring issues, sensor malfunctions, or software glitches in the airbag control unit. If this code appears, it’s crucial to address it promptly to ensure that all safety systems are functional. Ignoring this warning can lead to compromised vehicle safety, especially during collisions. It’s recommended to have a qualified technician diagnose the issue using specialized tools like the GeekOBD APP, which can provide detailed insights into the fault and guide the necessary repairs.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B103E is present:
- The airbag warning light remains illuminated on the dashboard, indicating a malfunction in the airbag system.
- Unusual beeping or chimes that signal a warning related to the airbag system, which may occur intermittently.
- Decreased functionality of the side airbag system, which may not deploy during a collision, risking passenger safety.
- An inability to reset the airbag light after repairs have been made, suggesting ongoing issues with the airbag system.
- Potentially poor communication with the vehicle's onboard computer, leading to other related fault codes showing up.
Possible Causes
Most common causes of B103E (ordered by frequency):
- The most common cause is damaged wiring or connectors related to the airbag sensor, occurring in approximately 60% of cases. This may arise due to wear and tear, corrosion, or physical damage.
- Another frequent issue is a malfunctioning side impact sensor itself, accounting for about 25% of B103E codes. This can happen due to manufacturing defects or exposure to extreme conditions.
- Poor maintenance practices, such as failing to keep wiring harnesses protected from moisture and debris, may also lead to this code appearing. Regular checks can help prevent this.
- Less common but serious causes include failures in the airbag control module, which could cause the entire airbag system to malfunction.
- A rare cause might be software glitches within the vehicle's onboard computer, which can often be resolved with a software update.

Diagnostic Steps
Professional B103E Diagnosis Process
Follow these systematic steps to accurately diagnose B103E. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct an initial visual inspection of the airbag wiring and connectors
Step 1: Conduct an initial visual inspection of the airbag wiring and connectors. Check for visible damage or corrosion, which can take about 5-10 minutes.
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan to retrieve all trouble codes and freeze-frame data
Step 2: Use the GeekOBD APP to perform an OBD2 scan to retrieve all trouble codes and freeze-frame data. This step can help provide context for the B103E code, taking around 10-15 minutes.
Step 3: Step 3: Perform component testing on the airbag sensor and its connections using a multimeter to ensure proper voltage and continuity
Step 3: Perform component testing on the airbag sensor and its connections using a multimeter to ensure proper voltage and continuity. This step may take 20-30 minutes.
Step 4: Step 4: After making any repairs, conduct a system function test to verify that the airbag system is operational and clear any codes from the memory, which can take about 10-15 minutes
Step 4: After making any repairs, conduct a system function test to verify that the airbag system is operational and clear any codes from the memory, which can take about 10-15 minutes.
