What Does B007F Mean?
This code indicates a malfunction in the deployment control circuit for the passenger seatbelt pretensioner 'C' (typically associated with rear passenger or third-row seating positions). The restraint control module has detected an electrical fault or abnormal resistance in the pretensioner deployment circuit that could prevent proper operation during a collision. This is a subfault code, meaning it represents a specific component within the broader restraint system.
Safety Warning
This is a critical safety system fault that could prevent the seatbelt pretensioner from deploying in a collision, increasing injury risk to occupants. The vehicle is technically drivable but the restraint system is compromised; repair should be completed immediately and the affected seating position should not be used until repaired.
Common Causes
35%
Faulty seatbelt pretensioner assembly or internal circuit failure
30%
Damaged, corroded, or disconnected wiring harness between restraint module and pretensioner
20%
Restraint control module internal failure or software corruption
10%
High resistance in pretensioner circuit due to poor ground connection or corroded terminals
5%
Previous deployment or collision damage requiring system replacement
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger seatbelt pretensioner C and its connector for physical damage, corrosion, water intrusion, or signs of previous deployment (pretensioners are single-use devices)
2
Step 2: Using a digital multimeter, measure resistance across the pretensioner connector terminals (disconnected from harness) - typical resistance should be 2-3 ohms; infinite resistance or short to ground indicates pretensioner failure
3
Step 3: Inspect wiring harness from restraint control module to pretensioner C for chafing, cuts, pinched wires, or damaged insulation; pay special attention to areas where harness passes through body panels or under seats
4
Step 4: Measure voltage at pretensioner connector with ignition on - should see battery voltage briefly during system self-check; absence of voltage indicates wiring harness or module issue
5
Step 5: Check all ground connections in the restraint system circuit, clean and tighten ground points, and verify continuity from pretensioner ground to chassis ground (less than 0.5 ohms)
6
Step 6: If all wiring and pretensioner test within specifications, verify restraint control module is receiving proper power and ground; consider module reprogramming or replacement if all external components test good

The most common cause of B007F (Passenger Seatbelt Pretensioner "C" Deployment Control (Subfault)) is: Faulty seatbelt pretensioner assembly or internal circuit failure
Typical repair costs for B007F range from $300 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is a critical safety system fault that could prevent the seatbelt pretensioner from deploying in a collision, increasing injury risk to occupants. The vehicle is technically drivable but the restraint system is compromised; repair should be completed immediately and the affected seating position should not be used until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B007F to identify the root cause.
