What it means
The restraint module monitors the deployment circuit for the second-row left inflatable seatbelt. It sets this code when the circuit’s measured electrical characteristics are outside the expected range.
At a glance
- Usually lights the airbag (SRS) or body-system warning light
How it works
The restraint control module monitors the deployment circuit for the second-row left inflatable seatbelt, whose inflator widens the belt webbing in a crash. It stores B00F2 when the circuit’s electrical characteristics are outside the expected range, which may prevent this left-side belt from deploying correctly.
Common causes
Most likely first.
- Open or short in inflatable belt deployment circuit
- Damaged wiring or connector
- Failed belt inflator
- Fault in the restraint control module
Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
How to diagnose it
- Scan the restraint module for B00F2 and companion codes, and save freeze-frame or event data before clearing the fault.
- Inspect the second-row left inflatable belt, retractor area, and nearby trim for damage, moisture, or recent seat or interior work.
- After disabling the restraint system according to the maker’s instructions, inspect the left belt deployment connector and harness for corrosion, loose pins, pinching, or abrasion.
- Check the second-row left deployment circuit for an open or short using the manufacturer’s specified equipment and method; never probe the inflator with an ordinary meter.
- If circuit checks pass, follow the approved diagnostic procedure to assess the left inflatable belt assembly and restraint control module.
Common fixes
- Reconnect or repair the second-row left belt circuit wiring using the approved repair procedure.
- Replace a damaged connector or harness section found on the left deployment circuit.
- Replace the second-row left inflatable belt assembly if testing confirms its inflator has failed.
- Repair or replace the restraint control module if testing identifies an internal fault.
Can I keep driving?
The second-row left inflatable belt may not widen during a crash, reducing the protection it is designed to provide. Do not rely on this belt’s added inflatable-belt function until repaired, and follow the maker’s precautions around the inflator.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
