Can I drive my car with B048E or should I stop immediately?
It is unsafe to drive your vehicle with B048E present, as your airbag may not deploy in an accident. You should seek immediate repairs to ensure your safety.
How can I diagnose B048E myself using GeekOBD APP?
To diagnose B048E using the GeekOBD APP, connect your device to the vehicle's OBD2 port, scan for trouble codes, and review the freeze frame data to understand the conditions under which the code was triggered.
What vehicles are most commonly affected by B048E?
B048E is commonly found in 2015-2018 Chevrolet Malibu, Buick Regal, and other General Motors vehicles. Always check for any recalls or Technical Service Bulletins (TSBs) related to airbag systems.
How can I prevent B048E from happening again?
Regularly inspect the airbag system, including wiring and connectors, and ensure that any recalls or recommended maintenance are addressed promptly to prevent future issues.
What is B048E?
The B048E diagnostic trouble code indicates a problem with the passenger airbag status indicator circuit. This code is primarily related to the airbag system, which is crucial for passenger safety in vehicles like the 2015-2018 Chevrolet Malibu, Buick Regal, and other GM models. When this code triggers, it typically means that the vehicle's onboard diagnostics have detected an issue with the airbag status indicator that could prevent the airbag from deploying in the event of an accident. In practical terms, this means that your airbag may not function correctly when needed, which poses a significant safety risk. The problem could stem from a faulty airbag module, broken wiring, or a malfunctioning sensor. Ignoring this code is not advisable as it could result in severe consequences during a collision. If the airbag light is illuminated on your dashboard, it is essential to address this issue promptly to ensure that you and your passengers are protected in the event of an accident.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B048E is present:
- The airbag warning light remains illuminated on the dashboard, indicating a potential fault in the airbag system.
- A noticeable lack of response in the passenger airbag indicator light when the ignition is turned on, suggesting the system is not functioning.
- Inconsistent passenger airbag status messages shown on the dashboard, which may confuse the driver regarding the airbag's readiness.
- No deployment of the airbag during a simulated test or real accident, which could lead to severe injuries.
- Increased risk of personal injury due to non-functional airbag system.
Possible Causes
Most common causes of B048E (ordered by frequency):
- Faulty airbag module - 40% likelihood. This is the most common issue and can often be resolved by replacing the module.
- Damaged wiring or connectors - 30% likelihood. Corroded or disconnected wires can interrupt the signal to the airbag system.
- Malfunctioning passenger seat sensor - 20% likelihood. This sensor determines whether the airbag should be activated based on occupancy.
- Software issues within the airbag control unit - 5% likelihood. Sometimes a simple software update can resolve the problem.
- Rare malfunctioning of the airbag indicator itself - 5% likelihood. This could lead to incorrect readings, complicating diagnostics.

Diagnostic Steps
Professional B048E Diagnosis Process
Follow these systematic steps to accurately diagnose B048E. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct a visual inspection of the airbag system components
Step 1: Conduct a visual inspection of the airbag system components. Look for disconnected or damaged wiring and connectors (5-10 minutes).
Step 2: Step 2: Use a compatible OBD2 scanner, like the GeekOBD APP, to read the DTCs and freeze frame data
Step 2: Use a compatible OBD2 scanner, like the GeekOBD APP, to read the DTCs and freeze frame data. This will help contextualize the fault (10-15 minutes).
Step 3: Step 3: Test the suspected components using a multimeter to check for continuity and proper functionality (20-30 minutes)
Step 3: Test the suspected components using a multimeter to check for continuity and proper functionality (20-30 minutes).
Step 4: Step 4: Clear the DTCs and perform a system function test to ensure everything operates as it should (10-15 minutes)
Step 4: Clear the DTCs and perform a system function test to ensure everything operates as it should (10-15 minutes).
Step 5: Step 5: Conduct a road test to verify the airbag system responds correctly under normal driving conditions (15-20 minutes)
