B00F7Third Row Right Inflatable Seat Belt Deployment Control

Q: What does code B00F7 mean?

Third Row Right Inflatable Seat Belt Deployment Control. B00F7 indicates that the restraint control module has detected a fault in the deployment circuit for the third-row right inflatable seat belt, which is a seat belt that inflates like an airbag during a crash to spread forces across the occupant's torso. The module monitors circuit resistance and continuity and sets this code when the reading falls outside the expected range, disabling deployment of that belt.

AreaAirbags, seats, doors, lights and comfort systems

Symptoms you may notice

Airbag or supplemental restraint warning light illuminated on the dashboard
Seat belt warning light or chime that stays on after buckling
Often no symptoms besides the warning light, with the belt functioning normally as a passive restraint
The third-row right inflatable seat belt may not deploy in a collision
In some vehicles, a message on the driver information center stating the restraint system needs service
Other restraint system functions may be inhibited until the fault is repaired

Common causes, most likely first

Damaged or disconnected electrical connector at the third-row right inflatable seat belt module
Chafed, pinched, or broken wiring in the seat belt circuit, often where the seat folds or slides
Failed inflatable seat belt module or its internal deployment squib
Corrosion or water intrusion at the connector or module, especially in vehicles with rear climate or leak issues
Faulty restraint control module (RCM) not properly reading the circuit
Poor ground connection for the restraint system at the third-row location
Aftermarket accessories or previous seat removal that disturbed the belt wiring

How to diagnose and fix it

Inspect the third-row right seat belt connector for looseness, corrosion, or bent pins and reseat it firmly
Check the wiring harness along the seat path for chafing, pinches, or breaks and repair as needed
Measure resistance across the inflatable seat belt squib with a meter to compare against the manufacturer's specification
Verify ground continuity and power at the restraint control module connector
Clear the code and recheck; if it returns, substitute a known-good inflatable seat belt module to isolate the fault
If the circuit tests good but the code persists, diagnose or replace the restraint control module per factory procedures
After repair, perform the required restraint system verification and clear all codes

What most technicians miss on B00F7

A common oversight is replacing the inflatable seat belt module before checking the connector under the third-row seat, where folding seats routinely pinch or pull the wiring.
The code can be set by a low battery or voltage spike during cranking, so always check for a stable power supply and clear history codes before condemning parts.
Inflatable seat belts are often mistaken for standard belts, so technicians may overlook the inflator connector and squib circuit entirely.
Water leaks from rear climate drains or liftgate seals can corrode the third-row connector and set this code without any visible damage.
The restraint control module may store this code after a minor impact or seat removal, and a simple reset and road test can confirm whether it is a hard fault.

Can I keep driving with B00F7?

The vehicle remains driveable, but the third-row right inflatable seat belt will not deploy in a crash, so avoid carrying passengers in that seating position until the fault is repaired. Have the restraint system diagnosed promptly, as other airbag functions may also be affected.
