What is B0517?
The diagnostic trouble code (DTC) B0517 indicates an issue with the airbag system's passenger side, specifically linked to the passenger presence system (PPS) or the seat occupancy sensor. This code generally means that the airbag control module has detected a malfunction in the passenger airbag system, which can potentially prevent the airbag from deploying in the event of an accident. For many vehicle owners, particularly those with models like the 2016-2020 Ford Explorer or the 2017-2021 Chevrolet Equinox, this can raise concerns about safety and vehicle performance. Common symptoms associated with B0517 include the illumination of the airbag warning light on the dashboard, which alerts drivers that there is an issue with the airbag system. While it may seem like a minor issue, neglecting this code could have serious implications, as a malfunctioning airbag system may not provide adequate protection during a collision. Therefore, addressing the B0517 code promptly is crucial to ensure passenger safety and compliance with vehicle regulations.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0517 is present:
- The airbag warning light remains illuminated on the dashboard, indicating a malfunction in the airbag system.
- The passenger airbag may not deploy in the event of a crash, posing serious safety risks.
- Inconsistent passenger seat sensor readings can lead to the airbag turning off when occupied, potentially causing issues during an accident.
- You may notice that the seatbelt indicator for the passenger seat does not function correctly, leading to confusion and safety concerns.
- In rare cases, a noticeable delay in airbag deployment during a collision simulation might be detected through diagnostic tools.
Possible Causes
Most common causes of B0517 (ordered by frequency):
- The most common cause of the B0517 code is a faulty passenger presence sensor, which occurs in about 60% of cases. This sensor detects whether a passenger is seated and whether the airbag should be activated.
- Another cause can be damaged or corroded wiring in the airbag system, which can result in poor connectivity and trigger the code. This is often due to wear and tear or improper installation during repairs.
- A malfunctioning airbag control module itself can also lead to the B0517 code, although this is less common and occurs in about 15% of cases. Regular maintenance and checks can help prevent this.
- Less frequent but serious causes include the deployment of the airbag system due to a crash that wasn't properly reset, which can lead to the B0517 code appearing post-accident.
- In rare instances, software issues within the vehicle's onboard computer can also trigger the B0517 code, requiring a software update or reprogramming to resolve.

Diagnostic Steps
Professional B0517 Diagnosis Process
Follow these systematic steps to accurately diagnose B0517. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Start with an initial visual inspection to check for obvious issues such as damaged wiring or loose connections related to the airbag system (5-10 minutes)
Step 1: Start with an initial visual inspection to check for obvious issues such as damaged wiring or loose connections related to the airbag system (5-10 minutes).
Step 2: Step 2: Use an OBD2 scanner or the GeekOBD APP to retrieve all stored codes and freeze frame data
Step 2: Use an OBD2 scanner or the GeekOBD APP to retrieve all stored codes and freeze frame data. This will give a clearer context of the fault (10-15 minutes).
Step 3: Step 3: Proceed to component testing
Step 3: Proceed to component testing. Use a multimeter or specific diagnostic tools to evaluate the passenger presence sensor and wiring integrity (20-30 minutes).
Step 4: Step 4: After making any repairs, perform a system function test to verify that the airbag system operates correctly and clear any codes (10-15 minutes)
Step 4: After making any repairs, perform a system function test to verify that the airbag system operates correctly and clear any codes (10-15 minutes).
Step 5: Step 5: Conduct a road test under various conditions to confirm that the repair is successful and that the airbag system is functioning properly (15-20 minutes)
Step 5: Conduct a road test under various conditions to confirm that the repair is successful and that the airbag system is functioning properly (15-20 minutes).
