Need SRS wiring diagrams and connector views for this code?
SRS/airbag circuit faults require OEM connector views, harness routing diagrams, and approved test procedures. A repair manual helps you verify the exact circuit path safely before touching SRS components.
B007213 is a Toyota SRS code that records an open circuit in the passenger seat belt pretensioner “A” deployment loop. FTB :13 indicates the SRS module’s supervision current has stopped flowing through the pretensioner squib circuit. On a crash-damaged vehicle where the pretensioner has fired, this is an expected post-deployment record — the squib element inside the pretensioner is consumed by the deployment event, creating the open circuit the module records as B007213. Seat belt pretensioners are single-use pyrotechnic devices and cannot be reset or reused after firing. This code requires pretensioner replacement as part of a complete post-crash SRS repair.

B007213 Quick Answer
B007213 on a Toyota means the SRS module detected an open circuit in the passenger front seat belt pretensioner “A” squib loop. After a collision where the pretensioner fired, the squib is consumed and the circuit is permanently open. The pretensioner must be replaced as part of a full post-crash SRS repair that also includes the SRS module and all other deployed components. The passenger seat belt is non-functional as a restraint until the pretensioner is replaced and the system recommissioned.
What Does B007213 Mean?
Seat belt pretensioners are pyrotechnic devices integrated into the seat belt retractor or buckle assembly. On the RAV4 PHV, the passenger “A” pretensioner fires in a qualifying frontal or lateral impact to instantly retract the belt webbing, removing slack and pulling the occupant firmly into their seat before the airbags deploy. This reduces the distance the occupant travels before the airbag contacts them, significantly improving restraint effectiveness.
Like an airbag squib, the pretensioner firing element is a one-time device. When it fires, the resistive wire bridge inside the squib burns through, creating an open circuit. The SRS module, which monitors all pretensioner circuits through a supervision current, records this open as B007213 FTB :13. In the context of a crash where P05BB00 “Restraints deployed” is also present, B007213 confirms the passenger pretensioner fired as intended. The fault code is a deployment record, not a diagnostic target.
Theory of Operation
The SRS module monitors the passenger pretensioner circuit continuously via a small current through the squib bridge. This supervision current verifies circuit integrity without triggering the pyrotechnic element. In a qualifying crash event, the module sends a firing current through the circuit, which ignites the propellant in the pretensioner gas generator. The gas drives a piston that rotates the retractor spool, retracting the belt webbing by typically 100–150mm in under 25 milliseconds.
After firing, the squib bridge is consumed. The pretensioner mechanism is mechanically locked in the retracted position. The belt cannot be extended normally — the retractor is permanently locked. This is a visible indicator of pretensioner deployment that a technician can confirm without scan tool access. The SRS module records the open squib circuit as B007213 and will continue to log it at every key-on cycle until the pretensioner assembly is replaced.
Symptoms
- Passenger seat belt locked and shortened: The pretensioner has retracted the belt webbing. The belt cannot be pulled out and the shoulder belt position will be visibly higher than normal. This is a clear physical indicator of deployment.
- SRS warning light illuminated: On continuously after deployment, will not extinguish until all repairs are complete.
- B007213 confirmed in SRS module: Logged at every key-on cycle until the pretensioner is replaced.
- Passenger restraint non-functional: The seat belt cannot be used normally with the pretensioner fired and locked. The passenger seat offers no belt restraint protection.
- Concurrent SRS deployment codes: B002013, B002111, B002113, B007313, and P05BB00 present simultaneously indicate a multi-component deployment event.
Pretensioner vs Airbag — Different Components, Same Repair Priority
A common misunderstanding is that pretensioner replacement is less urgent than airbag replacement. Both are equally important. A pretensioner that has fired and locked the belt renders the seat belt non-functional for restraining an occupant in a subsequent impact. The belt webbing is held in the retracted position and cannot be extended to buckle a passenger. Additionally, the SRS module disables the entire system after any deployment, meaning airbags will not deploy in a second impact regardless of crash severity. All deployed components must be replaced before the SRS system can be recommissioned.
Repair Requirements
- Passenger seat belt pretensioner “A” replacement: The entire pretensioner and retractor assembly must be replaced with a new OEM Toyota unit. The pretensioner is typically integrated into the seat belt retractor — the complete assembly is replaced.
- Pretensioner squib harness inspection: Inspect the wiring between the SRS module and the pretensioner connector for damage from the crash forces or the deployment event.
- SRS airbag control module replacement: Required after any deployment event. Records crash data internally and must be replaced.
- All other deployed components: B002013, B002111/B002113, and B007313 indicate additional deployed components that must also be replaced.
- SRS recommissioning: Full circuit test on Toyota Techstream after all replacements, verifying all squib circuits read within specification.
Can I Still Drive With B007213?
No. The passenger seat belt pretensioner has fired and the belt is locked. A passenger cannot be safely restrained in this seat. The SRS system is also fully disabled, meaning no airbag protection is available for any occupant. The vehicle must not be driven until the complete collision and SRS repair is finished.
How Serious Is This Code?
Maximum severity. A fired pretensioner means the passenger cannot be safely belted into that seat. Combined with a fully disabled SRS system across all seating positions, the vehicle offers no crash protection for any occupant. This is a safety-critical condition requiring immediate repair before the vehicle is returned to service.
Common Misdiagnoses
Replacing the pretensioner and leaving the SRS module unreplaced is the most common oversight. The SRS module must be replaced after any deployment event — it stores crash data and deployment records that affect subsequent system function. Clearing the code without replacing hardware will result in immediate return of B007213 at the next key-on cycle. Another error is overlooking the locked seat belt as a sign of pretensioner deployment — a technician who only scans for codes without physically inspecting the belt may not notice the pretensioner has fired.
Most Likely Fix
Replacement of the passenger seat belt pretensioner assembly, replacement of the SRS module, and replacement of all other deployed components indicated by concurrent SRS codes. Full SRS recommissioning on Toyota Techstream is required to confirm all circuits are within specification before return to service.

Key Takeaways
- B007213 FTB :13 records an open circuit in the passenger pretensioner squib — after deployment, the squib is consumed and the circuit is permanently open until the assembly is replaced.
- The passenger seat belt is physically locked and cannot be used for occupant restraint until the pretensioner is replaced.
- Pretensioner replacement is as safety-critical as airbag replacement — both must be completed before the vehicle is returned to service.
- The SRS module must also be replaced after any deployment event, not just the individual deployed components.
- Only OEM Toyota pretensioner assemblies should be used — these are safety-critical components not suitable for aftermarket substitution.
FAQ
Can the pretensioner be reset or recharged?
No. A seat belt pretensioner is a single-use pyrotechnic device. Once fired, the gas generator is consumed and the mechanism is permanently locked. There is no reset procedure. The complete pretensioner and retractor assembly must be replaced with a new unit.
How do I know if the pretensioner has fired without a scan tool?
Pull the shoulder belt webbing out of the retractor. If the belt cannot be extended — the retractor is locked solid and will not feed webbing — the pretensioner has fired. You may also notice the seat belt is positioned higher than normal because the webbing has been retracted by 100–150mm. This physical check is a quick confirmation before using a scan tool.
Does the seat belt webbing also need to be replaced?
The webbing itself may not be damaged, but the retractor and pretensioner assembly that it is wound onto must be replaced. On most Toyota platforms the pretensioner is integrated into the retractor, so the complete assembly (retractor + pretensioner + webbing) is replaced as a single unit.
Will this repair be covered by insurance?
SRS component replacement resulting from a collision is typically covered under collision or comprehensive insurance. A pretensioner that fired in a crash is a collision-related repair. Contact your insurer and have a detailed estimate from the repair facility before authorising work.
Why does the SRS module need to be replaced if only the pretensioner fired?
The SRS module on the RAV4 PHV records deployment data and crash event information in non-volatile internal memory. This data affects the module’s function in future events. Toyota requires module replacement after any deployment — the stored crash records cannot simply be cleared, and the module’s internal algorithms may be altered by the deployment event processing. A replacement module is coded to the vehicle and starts with a clean deployment history.
