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.
B002013 is a Toyota SRS code that records an open circuit in the left side airbag squib deployment loop. On a vehicle that has been in a collision where the left side airbag deployed, B002013 is an expected post-deployment fault — not a pre-existing wiring problem. The squib (the firing element inside the airbag inflator) is a one-time device. Once it fires, the deployment loop is physically burned open, and the SRS airbag control module records the open circuit as B002013 with FTB :13. This code is evidence of a crash event. The vehicle requires professional collision repair before it can be returned to road use.

B002013 Quick Answer
B002013 on a Toyota means the SRS module detected an open circuit in the left side airbag squib deployment loop. If the left side airbag has deployed in a collision, this code is the expected post-crash record of that deployment. The circuit is open because the squib fired and physically burned through. The repair path is collision body repair, replacement of the deployed airbag assembly, replacement of the SRS airbag control module, and professional recommissioning of the entire SRS system — not wiring diagnosis or component testing.
What Does B002013 Mean?
The Toyota SRS system monitors each airbag squib circuit continuously through a small supervision current. The squib is a resistive bridge element inside the airbag inflator. When the SRS module detects the supervision current is no longer flowing — meaning resistance is infinite — it records an open circuit fault. FTB :13 in Toyota SRS coding specifically classifies this as an open circuit condition in the deployment control loop.
On a vehicle that has not been in a collision, B002013 could indicate a genuine pre-crash wiring fault — a broken wire, corroded connector, or failed squib element. However, when B002013 appears alongside P05BB00 “Restraints deployed” and other deployment circuit codes, the diagnosis is clear: the left side airbag fired in a collision, the squib is consumed, and the circuit is open as a direct result of deployment. These are crash event records, not faults to diagnose.
Theory of Operation
Toyota’s SRS architecture uses a dedicated firing circuit for each individual airbag and pretensioner. The left side airbag protects the driver from lateral impact by deploying from the seat back or door trim to cushion the thorax and pelvis. Its squib is a small pyrotechnic element connected to the SRS module via a two-wire loop. The module supplies a small continuous supervision current through this loop to verify circuit integrity. In a crash event meeting the threshold criteria, the module sends a high-current firing pulse through the squib, igniting the propellant and inflating the airbag in milliseconds.
Once the squib fires, the thin resistance wire inside it is consumed. The circuit becomes an open — infinite resistance. The SRS module, which continues to monitor all circuits after the crash, records the open in the B002013 code. This is by design: the fault record serves as documentation of which airbag deployed, which is essential information for the collision repair facility, the SRS technician, and in some jurisdictions, the insurance inspector. It is not a malfunction of the SRS system — it is the system accurately reporting what happened.
Symptoms
- SRS/airbag warning light illuminated: The SRS module illuminates the warning after any deployment and will not extinguish until all deployed components are replaced and the module is reset or replaced.
- Left side airbag visibly deployed: The airbag will be visible in the seat back or door trim, deflated after deployment. The trim panel and seat cover will show deployment damage.
- B002013 stored in SRS module: Confirmed/TestFailed status indicates the module has tested the circuit and confirmed the open fault.
- Multiple concurrent SRS codes: B002013 will appear alongside P05BB00 and other deployment codes for any other components that fired in the same event.
- SRS system disabled: All airbag and pretensioner functions are disabled after a deployment event. The vehicle offers no SRS protection until the system is fully repaired and recommissioned.
- Collision damage: Structural, body, or trim damage consistent with the impact that triggered the deployment will be present.
Post-Crash Inspection Requirements
A vehicle with B002013 and confirmed airbag deployment requires a structured post-crash SRS inspection before any repair work begins. The inspection must be performed by a qualified SRS technician using Toyota-approved diagnostic equipment. The following must be assessed:
- SRS module status: The airbag control module records crash data and deployment events internally. After deployment, the module must be either replaced or, if Toyota allows it for the specific vehicle, reflashed and re-certified. Most Toyota platforms require full SRS module replacement after deployment.
- All deployed components: Every airbag and pretensioner that fired must be identified through the stored fault codes and confirmed through physical inspection. B002013 identifies the left side airbag as deployed; other codes identify additional deployed components.
- Structural integrity: The mounting points for airbags, the SRS module, and seat belt pretensioners must be inspected for deformation. A distorted mount affects the performance of replacement components.
- Clock spring and wiring: The wiring harness serving the SRS system must be inspected for heat damage, crush damage, or insulation failure caused by the crash or the deployment event.
- Non-deployed airbags: Airbags that did not deploy must be inspected for physical damage from the crash. An airbag housing that is cracked or deformed cannot be returned to service even if the inflator was not triggered.
Why This Is Not a Standard Wiring Fault
B002013 with FTB :13 could in theory appear on a vehicle that has not been in an accident — if the squib element failed internally or the wiring was damaged by corrosion or mechanical stress. In that scenario, circuit resistance testing, connector inspection, and squib resistance measurement would be the diagnostic path. However, when B002013 co-exists with P05BB00 “Restraints deployed” and multiple other deployment circuit codes, there is no diagnostic ambiguity. The circuit is open because the squib fired. Attempting to test or repair the squib circuit in isolation — without addressing the crash damage and replacing the deployed assembly — is both incorrect and dangerous.
Repair Requirements
Repairing a vehicle with B002013 after a collision is not a simple parts swap. The following repairs are mandatory:
- Left side airbag assembly replacement: The entire airbag module including the inflator and deployed bag must be replaced. Only new, OEM-specification Toyota parts should be used. Aftermarket SRS components carry safety risks that cannot be verified without Toyota’s testing data.
- SRS airbag control module replacement: The module stores deployment data and crash records. Toyota requires module replacement after deployment on most RAV4 PHV platforms. If a remanufactured module is permitted, it must be coded to the vehicle and tested on Toyota Techstream or equivalent.
- Seat trim and structural components: Trim panels, seat covers, and any structural members distorted by the deployment or the impact must be replaced to ensure the new airbag deploys correctly in a future event.
- All other deployed components: Any airbag or pretensioner indicated by concurrent SRS codes must be replaced in the same repair event.
- SRS system recommissioning: After all replacements, the SRS system must be tested on Toyota diagnostic equipment to confirm all circuits are within specification, all codes are cleared, and no new faults are present.
Can I Still Drive With B002013?
No. A vehicle with a deployed airbag, active SRS fault codes, and confirmed crash damage should not be driven on public roads. The SRS system is non-functional — no airbag or pretensioner protection is available if a second impact occurs. Beyond the safety issue, the vehicle likely has structural, mechanical, or visibility damage from the collision itself that makes it unroadworthy. It must be transported to a qualified repair facility, not driven.
How Serious Is This Code?
Extremely serious. B002013 on a collision-damaged vehicle is the highest severity classification for an SRS fault. The vehicle has no passive restraint protection. Any secondary impact — even a minor one — will occur with no airbag or pretensioner response. The code also signals that the vehicle has undergone a significant crash event that requires a comprehensive structural and safety system inspection before the car is returned to service. Do not clear codes and return the vehicle to road use without completing all required repairs.
Common Misdiagnoses
The most dangerous misdiagnosis is treating B002013 as a standard open-circuit fault and attempting to repair the squib wiring or replace the squib connector without replacing the entire deployed airbag assembly and the SRS module. A squib circuit that has fired cannot be repaired by splicing wire — the inflator assembly must be replaced. A second common error is clearing SRS codes after a crash without replacing all deployed components. The codes will return immediately because the circuits remain open. A third mistake is using aftermarket SRS parts to reduce repair cost — airbag and pretensioner components that are not Toyota-OEM have not been validated for the specific deployment timing, force, and chemistry required by the RAV4 PHV platform.
Most Likely Fix
Replacement of the left side airbag assembly, replacement of the SRS airbag control module, repair of any collision-related wiring damage, and replacement of all other deployed SRS components identified by concurrent fault codes. The repair must be followed by a full SRS system function test on Toyota-approved diagnostic equipment before the vehicle is returned to service.
Repair Costs
Post-crash SRS repair is significantly more expensive than standard maintenance. Costs below are approximate and depend on the extent of collision damage.
| Repair Type | Estimated Cost |
|---|---|
| Left side airbag assembly (OEM) | $400 – $900 |
| SRS airbag control module replacement | $500 – $1,500 |
| Wiring harness repair (if damaged) | $200 – $600+ |
| SRS recommissioning / diagnostic labour | $150 – $300 |
| Full post-crash SRS repair (all components) | $2,000 – $6,000+ depending on extent |

Key Takeaways
- B002013 records an open circuit in the left side airbag squib — when the airbag has deployed, this is a crash event record, not a wiring fault to diagnose.
- FTB :13 (open circuit) is the expected result after squib firing — the deployment element burns through by design.
- The repair requires replacement of the airbag assembly, the SRS module, and all other deployed components — not wiring repair.
- The vehicle must not be driven until all SRS repairs are complete and the system has been recommissioned on Toyota diagnostic equipment.
- Only OEM Toyota SRS parts should be used — aftermarket airbag and pretensioner components are not validated for the RAV4 PHV platform.
FAQ
Can I clear B002013 and drive the car safely?
No. Clearing the code does not restore SRS function. The airbag assembly is physically deployed and the circuit is permanently open until the assembly is replaced. The code will return immediately after clearing because the hardware fault is still present. The vehicle has no airbag protection until all repairs are complete.
Does B002013 mean the SRS module has failed?
No. The SRS module is functioning correctly — it deployed the airbag when required and is now accurately recording the post-deployment open circuit. However, Toyota requires SRS module replacement after a deployment event because the module stores crash data and deployment records internally. A replacement module is required as part of the full SRS repair.
Can an independent workshop repair this, or does it need a Toyota dealer?
A qualified SRS-certified independent workshop with access to Toyota Techstream or an equivalent OEM-level diagnostic tool can perform this repair. The critical requirements are OEM Toyota parts, correct SRS recommissioning procedure, and a post-repair function test that confirms all circuits are within specification and no fault codes remain.
Will insurance cover this repair?
SRS deployment repairs resulting from a collision are typically covered under comprehensive or collision insurance, subject to your policy terms and any applicable excess. Contact your insurer and have a detailed repair estimate from the collision repair facility before authorising work.
How long does a full post-crash SRS repair take?
A full SRS repair following airbag deployment typically takes 2–5 days at a qualified repair facility, depending on parts availability, the number of deployed components, and whether additional collision structural repair is required alongside the SRS work. OEM Toyota SRS parts may require ordering, which can extend the timeline.
