What Does B007C Mean?
This code indicates a malfunction in the deployment control circuit for the second seatbelt pretensioner on the right side of the second row. The restraint control module has detected an electrical fault in the secondary (B) pretensioner circuit that prevents proper deployment command or monitoring. This subfault designation suggests an intermittent or specific circuit condition within the pretensioner system that compromises the supplemental restraint system's ability to function correctly during a collision.
Safety Warning
This is a critical safety system fault that compromises occupant protection during a collision. The affected seatbelt pretensioner may fail to deploy properly in a crash, increasing injury risk to the second row right passenger. Immediate professional repair is required, and the vehicle should be driven only when necessary until repaired.
Common Causes
35%
Faulty seatbelt pretensioner unit with internal circuit degradation or moisture intrusion
30%
Damaged, corroded, or loose wiring harness connections between restraint module and pretensioner
20%
High resistance or open circuit in pretensioner deployment loop due to damaged wiring under seat
10%
Faulty restraint control module with internal deployment circuit failure
5%
Previous collision deployment with improper system reset or incomplete component replacement
Diagnostic Steps
1
Step 1: Perform visual inspection of second row right seatbelt pretensioner and wiring harness under seat for physical damage, connector corrosion, water intrusion, or signs of previous deployment (check for pyrotechnic discharge residue)
2
Step 2: Using a digital multimeter, measure resistance across pretensioner connector terminals (typically 2-5 ohms for squib circuit) and compare to manufacturer specifications; check for open circuits, shorts to ground, or shorts to power
3
Step 3: Inspect and test pretensioner connector terminals for proper seating, bent pins, corrosion, and back-probing condition; verify continuity from pretensioner connector back to restraint control module harness connector
4
Step 4: Check restraint control module connector for corrosion, moisture, or terminal damage; measure voltage supply and ground circuits to module to ensure proper power and ground integrity (typically 12V ignition feed and clean chassis ground)
5
Step 5: If all wiring and connections test within specifications, perform pretensioner replacement following proper SRS disarming procedures and verify system operation; if fault persists, suspect restraint control module
6
Step 6: After repairs, clear codes, perform restraint system self-test using scan tool, and verify SRS warning light extinguishes; conduct test drive and re-scan to confirm no fault return
Estimated Repair Cost
$300 - $1,200
