If your airbag or SRS warning light refuses to go out — even after fixing the cause — you’re not alone.
From flat batteries to sensor glitches, these lights can stick until you use the right diagnostic tool.
Here’s how to clear it properly and which scanners actually work in 2025.

Why Your Airbag (SRS) Light Stays On
The airbag light — or SRS (Supplemental Restraint System) indicator — warns of a potential issue with crash sensors,
wiring, or the control unit. After a flat battery or voltage drop, the ECU can store a low-voltage fault.
Even if everything works again, the fault must be manually cleared with a scan tool capable of reading SRS modules.
- Common causes: weak battery, seat-belt tensioner plug, steering clock-spring, impact sensor, or control-unit glitch.
- What doesn’t work: generic OBD-II readers. They only talk to the engine ECU — not the SRS system.
- What you need: a brand-specific or multi-brand scanner that can access and clear the airbag control unit.
Real-world note (SEAT Arona FR):
One of our customers contacted us after her SEAT Arona FR battery went flat. When she restarted the car, the airbag (SRS) warning light stayed on even though everything seemed normal.
In this case, the fault wasn’t due to a damaged component — it was a low-voltage error stored in the airbag control module. Using a VAG-compatible diagnostic tool such as the ANCEL VD700 she was able to read and safely clear the code within minutes.
This highlights a common issue: after a flat battery or jump start, many modern SEAT, VW, Audi, and Škoda vehicles log voltage-related SRS faults that require a scan tool to reset.
Tip: System coverage and reset functions can vary by model year and ECU type, so if you’d like to confirm whether a tool will clear your airbag light, contact our team with your VIN — we’ll check compatibility for you.
Best Tools to Clear Airbag Lights (2025)
These scanners are proven picks to access the SRS module and clear codes once the underlying fault is fixed.

How to Reset the Airbag Light (Step-by-Step)
- Connect your diagnostic tool — Plug into the OBD-II port (usually under the steering column).
- Ignition ON — Do not start the engine unless the tool prompts you.
- Select SRS/Airbag module — In “Control Unit” or “Body/Safety” menu.
- Read and note the code — e.g., “00532 – Supply Voltage B+ Low”.
- Fix the root cause — Battery/charging, connectors, clock-spring, sensors, etc.
- Clear fault codes — Light should go out immediately; if it returns, re-diagnose hardware.

Airbag Light FAQs
Can I clear the airbag light without a tool?
No — once triggered, the SRS module locks the fault. You need a proper diagnostic tool to clear it safely.
Will disconnecting the battery reset it?
Not usually. On most modern vehicles, codes persist in non-volatile memory.
Which tool is best for multiple cars?
iCarsoft CR MAX for ease, or ANCEL DS600 BT for deeper tests and modern protocol support.
