It's advised to stop driving the vehicle immediately as the airbag system may be inoperative, increasing the risk of injury in a collision.
How can I diagnose B0197 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for trouble codes, view live data from the airbag system, and check for any freeze frame data that might indicate the conditions under which the fault occurred.
What vehicles are most commonly affected by B0197?
Vehicles from Ford, Chevrolet, and other manufacturers like GMC and Dodge, particularly models from 2010 to 2020, often experience B0197.
How can I prevent B0197 from happening again?
Regularly inspect the airbag system, keep wiring and connectors clean, and ensure software updates are completed to prevent issues with the airbag system.
What is B0197?
The diagnostic trouble code (DTC) B0197 indicates an issue with the airbag sensor circuit, specifically related to the passenger airbag. This code is prevalent in vehicles from manufacturers like Ford and Chevrolet, particularly in models produced between 2010 and 2020. When this code appears, it usually signifies that the airbag control module has detected a malfunction in the circuit responsible for monitoring the passenger airbag sensor. This can happen due to a variety of factors, including damaged wiring, a faulty airbag sensor, or issues with the airbag control module itself. It's crucial to address this problem as soon as possible, not only to restore the functionality of your airbag system but also to ensure your safety and that of your passengers. If B0197 is present, it typically means that the airbag system will be disabled, which can significantly increase the risk of injury in the event of a collision. Ignoring this code can lead to costly repairs down the line and may even result in additional safety hazards. Proper diagnostic steps and repairs should be undertaken promptly to rectify the issue.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0197 is present:
- The airbag warning light remains illuminated on the dashboard, indicating a potential safety issue.
- The 'passenger airbag off' light may be activated even when a passenger is seated, suggesting a problem with the sensor.
- Increased difficulty in detecting the presence of a passenger, impacting the airbag deployment system.
- Unexpected airbag deployment during non-collision events may occur, leading to safety hazards.
- Inconsistent airbag functionality, where the airbag may not deploy in the event of a collision.
Possible Causes
Most common causes of B0197 (ordered by frequency):
- Damaged wiring or connectors in the airbag system, which is the most common cause (about 40% likelihood). This can result from wear and tear over time or environmental factors.
- A faulty passenger airbag sensor itself, which may fail due to age or manufacturing defects (30% likelihood). Regular inspections can help catch this early.
- Issues with the airbag control module, which can be due to software glitches or hardware failures (20% likelihood). Keeping the vehicle's software updated is crucial.
- Less common but serious causes include prior collision damage that affects the airbag system (5%). Even minor accidents can lead to undiagnosed wiring issues.
- Rare causes may include factory defects or wiring harness issues that are not visible during standard inspections (5%).

Diagnostic Steps
Professional B0197 Diagnosis Process
Follow these systematic steps to accurately diagnose B0197. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Start with an initial visual inspection of the airbag system wiring and connectors
Step 1: Start with an initial visual inspection of the airbag system wiring and connectors. Look for any visible damage, corrosion, or loose connections (5-10 minutes).
Step 2: Step 2: Use an OBD2 scanner to read all diagnostic trouble codes
Step 2: Use an OBD2 scanner to read all diagnostic trouble codes. Pay attention to freeze frame data which provides context about when the fault occurred (10-15 minutes).
Step 3: Step 3: Test the passenger airbag sensor using a multimeter to check for continuity and resistance, which will help identify if the sensor is functioning correctly (20-30 minutes)
Step 3: Test the passenger airbag sensor using a multimeter to check for continuity and resistance, which will help identify if the sensor is functioning correctly (20-30 minutes).
Step 4: Step 4: Conduct a system function test by manually triggering the airbag system to confirm proper operation after repairs
Step 4: Conduct a system function test by manually triggering the airbag system to confirm proper operation after repairs. Clear any codes and re-check (10-15 minutes).
Step 5: Step 5: Finally, take the vehicle for a road test under different conditions to ensure that the airbag system is fully operational and the warning lights behave normally (15-20 minutes)
Step 5: Finally, take the vehicle for a road test under different conditions to ensure that the airbag system is fully operational and the warning lights behave normally (15-20 minutes).
Important Notes
