Airbag Warning Light & SRS Fault Diagnosis Melbourne
Airbag Warning Light On?
Professional SRS & Seatbelt System Diagnosis Melbourne
If your airbag warning light is illuminated, your vehicle's Supplemental Restraint System (SRS) has detected a fault that requires diagnosis. At Melbourne Seatbelt Repairs, we use professional diagnostic equipment to accurately identify faults within the SRS system — including seatbelt pretensioners, buckles, occupancy sensors, wiring faults and airbag control modules. We don't simply clear fault codes. We identify the cause before recommending repairs.
"One of the biggest misconceptions we see is customers asking if we can simply turn the airbag light off. The warning light is there for a reason. Modern vehicles constantly monitor the entire Supplemental Restraint System. If a fault is detected, the control module stores a fault code to help identify the affected circuit or component. Using professional diagnostic equipment, we communicate directly with the SRS module, retrieve manufacturer-specific fault codes and accurately diagnose the cause of the warning light before any repairs begin."

Why Airbag Warning Lights Come On
The SRS warning light can be triggered by a wide range of faults. Some are straightforward — a disconnected connector or a seatbelt buckle switch fault. Others require detailed electrical diagnosis to identify. Common causes include:
A deployed or faulty pretensioner will trigger an SRS fault code. The pretensioner circuit is monitored continuously by the SRS module.
The buckle switch tells the SRS module whether the belt is fastened. A faulty switch or damaged connector can trigger a fault code.
Seat occupancy sensors detect whether a passenger is present and adjust airbag deployment accordingly. Faults are common after seat repairs or replacements.
The clock spring maintains electrical continuity between the steering column and the airbag, horn and steering controls. Failure triggers an SRS fault.
After a collision, the SRS module may store crash event data. On some vehicles, the module requires replacement or reprogramming before the system will reset.
Damaged, corroded or disconnected wiring within the SRS circuit can trigger fault codes. Accurate diagnosis requires electrical testing, not just code reading.
A significant voltage drop — from a flat battery or charging system fault — can trigger SRS fault codes that persist after the battery is restored.
The SRS control module itself can develop faults. Diagnosis determines whether the module requires replacement or reprogramming.
Our Diagnostic Process
Connect Professional Scan Tool
We connect professional diagnostic equipment directly to the vehicle's OBD port and establish communication with the SRS module.
Retrieve Manufacturer Fault Codes
We retrieve manufacturer-specific SRS fault codes — not generic codes. Manufacturer-specific codes identify the affected circuit or component accurately.
Live Data Analysis
Where required, we review live data from the SRS module to assess sensor readings, circuit status and system operation.
Electrical Testing
Fault codes identify the circuit — electrical testing confirms the cause. We test wiring, connectors and components as required to confirm the diagnosis.
Repair the Fault
Once the cause is confirmed, we carry out the repair. This may involve seatbelt components, wiring, connectors, sensors or other SRS components.
Reset & Road Test
After the repair, fault codes are cleared using professional equipment and the system is verified. A road test confirms correct operation before the vehicle is returned.
Professional SRS Diagnostic Equipment
Not every scan tool can communicate with every airbag system. Some cheaper scan tools may only read generic engine fault codes and have limited or no access to manufacturer-specific SRS modules. Generic codes — where available — often lack the detail required to accurately identify the cause of an SRS fault.
At Melbourne Seatbelt Repairs, we use professional diagnostic equipment capable of communicating with a wide range of vehicle manufacturers, allowing us to retrieve manufacturer-specific SRS fault codes and perform the diagnostic procedures required for many airbag systems.
Accurate diagnosis is the first step before any repair or reset is carried out. We don't guess — we diagnose.

Common SRS Faults We Repair
As seatbelt specialists, many of the most common SRS faults fall directly within our area of expertise.
- Seatbelt pretensioner faults — assessment, repair or replacement
- Crash-locked seatbelt retractors
- Seatbelt buckle switch faults
- Occupancy sensor faults
- Clock spring replacement
- SRS wiring repairs and connector replacement
- Seat wiring faults
- Airbag module diagnosis and crash data assessment (where applicable)
- SRS fault code retrieval and system reset after repair
You're not bringing your vehicle to a general mechanic. Melbourne Seatbelt Repairs are seatbelt specialists. Our technicians understand how the entire SRS system works together — from the webbing and retractor through to the pretensioner, buckle switch, wiring and control module. That specialist knowledge is the difference between a diagnosis and a guess.
Airbag Warning Light Reset
Once the underlying fault has been repaired, many vehicles require the SRS module to be reset and fault codes cleared using professional diagnostic equipment.
Simply clearing the code without repairing the fault is generally ineffective — the warning light will usually return if the issue remains. On some vehicles, crash event data stored in the SRS module cannot be cleared by a scan tool alone and may require module replacement or reprogramming.
We carry out SRS resets as part of the repair process — not as a standalone service to mask an unresolved fault.
Airbag Warning Light & Roadworthy Inspections
An illuminated airbag warning light is a seatbelt and restraint system fault indicator. Damage or faults within the SRS system may result in the vehicle being rejected during a roadworthy inspection. The final determination is made by the licensed vehicle tester.
If your vehicle has been identified as having an SRS fault during a roadworthy inspection, contact us to discuss diagnosis and repair options. See our roadworthy seatbelt repairs page for more information.
Vehicles We Diagnose
Contact us before your visit if you are unsure whether we can access your specific vehicle's SRS system. We will advise honestly.
Frequently Asked Questions
Can you just turn my airbag light off?
No — and we wouldn't. The warning light indicates a fault within the SRS system. Clearing the code without identifying and repairing the cause is generally ineffective, as the light will return if the fault remains. We diagnose the cause first, then carry out the repair, then reset the system.
Will my car pass a roadworthy with the airbag light on?
An illuminated SRS warning light may result in the vehicle being rejected during a roadworthy inspection. The final determination is made by the licensed vehicle tester. Contact us to discuss diagnosis and repair before your inspection.
Can you replace seatbelt pretensioners?
Seatbelt pretensioners require specialist assessment. If the pretensioner has deployed or the assembly has been involved in a collision, we assess the assembly and advise on whether repair or replacement is required. See our Pretensioner Assessment page.
Do you repair crash-locked seatbelts?
Yes. Crash-locked seatbelts are one of the most common post-accident repairs we carry out. See our Seatbelt Locked After Accident page.
Can you diagnose wiring faults within the SRS system?
Yes. Fault codes identify the affected circuit — we then carry out electrical testing to confirm the cause before any repairs are recommended.
Can you reset the SRS module after a repair?
Yes. After the underlying fault is repaired, we clear fault codes and reset the SRS system using professional diagnostic equipment. On some vehicles, crash event data may require module replacement or reprogramming rather than a standard reset.
My airbag light came on after a battery replacement. What happened?
A significant voltage drop during a battery replacement can trigger SRS fault codes that persist after the new battery is fitted. In many cases, the codes can be cleared once the system has been checked and no underlying fault is present. Contact us to discuss.
Do you work on commercial vans?
Yes. We regularly diagnose and repair SRS faults on commercial vans including Toyota HiAce, Ford Transit, Mercedes-Benz Sprinter, Volkswagen Crafter, Hyundai iLoad and LDV models.
