Picture this. You reverse into a bollard in a car park. Minor damage, couple hundred dollars. You take it to the nearest place, get the bumper fixed, and drive away thinking that’s the end of it.
A few weeks later your automatic braking does something strange. Your lane-keeping system starts pulling at odd moments. Your parking sensors beep at nothing.
The bumper looks perfect. Paint matches. But no one ever recalibrated the sensors sitting behind it.
This is happening to Adelaide drivers right now, and most of them have no idea it’s even a thing.
What Is ADAS and Why Should You Care?
ADAS stands for Advanced Driver Assistance Systems. It’s everything that makes your car feel like it’s partly driving itself. The camera behind the windscreen. The radar in the bumper. The sensors that slam on the brakes when someone steps out in front of you.
It’s not just Teslas and BMWs anymore. Automatic emergency braking has been mandatory on all new car models launched in Australia since 2023, with the requirement extended to all models available for sale from March 2025. Which means if you’re driving something bought in the last few years, you have this stuff.
Lane departure warning. Blind spot monitoring. Adaptive cruise. Forward collision alert. Rear cross-traffic systems. Most new Toyotas, Mazdas, Subarus, Hyundais, Kias and Fords are loaded with it.
Every single one of those systems has sensors aimed at very precise angles. And when something hits your car, those angles can shift.
Here’s the Part Nobody Tells You
The sensors in your car are not robust in the way a bumper bar is robust. They’re calibrated to factory specification, meaning they need to be pointing at exactly the right spot to do their job properly. We’re talking fractions of a degree.
A collision doesn’t have to be serious to knock them out. In fact, the types of repairs that most commonly require recalibration include:
- Front or rear bumper removal or replacement (even minor)
- Windscreen replacement
- Front or rear quarter panel repair
- Any airbag deployment
- Wheel alignment adjustment
- Suspension work
- Battery disconnection
That last one surprises people. Disconnecting the battery can wipe calibration data on some systems. Your car genuinely doesn’t always tell you this has happened.
I-CAR, which is the peak collision repair training body in Australia, is clear on this: any vehicle with ADAS that’s been involved in a collision will likely need calibration checked, regardless of how bad the impact looked.
Static Calibration vs Dynamic Calibration
There are two types, and they’re quite different.
Static calibration happens in a workshop. The car is parked on a level surface and specialist targets are positioned at precise distances in front of it. The sensors read those targets and align themselves against a known reference point. It requires specific equipment, controlled lighting and a workshop big enough to set it all up correctly. You can’t do it in a driveway.
Dynamic calibration means the car needs to be driven. Specific speeds, roads with clear lane markings, for a set amount of time while the system recalibrates on the move.
Some manufacturers require one or the other. Some require both, in a specific order. There’s no single answer that applies across all vehicles, which is part of why it’s a specialist job.
What Goes Wrong When It Doesn’t Get Done
This is where it gets serious.
A miscalibrated ADAS sensor doesn’t always throw up a warning light. The system might look like it’s working. It might work fine in everyday driving for months. But in the specific moment it’s supposed to intervene, whether that’s a car running a red light, a child stepping into the road, a vehicle merging too fast, it might not.
Some specific things that happen with uncalibrated sensors:
False triggers. Your automatic emergency braking fires when there’s nothing there. At highway speed, this is genuinely dangerous.
Missed hazards. More concerning. The sensor is off-angle and doesn’t see what it should. The safety system that was supposed to help you simply doesn’t.
Insurance and legal headaches. If you’re in a subsequent accident and it comes out that sensors weren’t recalibrated after prior repairs, the questions get complicated fast. Documentation matters here. It’s also worth knowing your rights when choosing a repairer in South Australia before you commit to any shop after an accident.
Resale issues. Some manufacturers flag incomplete calibration in the vehicle’s service history. Buyers and dealers are starting to notice.
Not Every Repairer Can Actually Do This
Here’s the honest truth. Proper ADAS calibration requires manufacturer-approved diagnostic equipment, not generic scan tools. It requires a controlled workshop environment with specific minimum dimensions. It requires calibration targets made to exact measurements for each make and model.
And it requires technicians who are trained on manufacturer-specific procedures, not just generally familiar with the concept.
A repairer without this investment will complete your visible repair work, hand you back your car, and leave your sensors wherever they ended up after the impact. Sometimes they won’t even realise calibration was needed.
At Eblen Collision Repairs in Somerton Park, our technicians hold I-CAR Gold Class certification, which is the highest ongoing training standard in the Australian collision repair industry. The key word is ongoing. It’s not a certificate you get once and hang on the wall. Technicians have to keep training as new vehicles and new systems are released. You can read more about what makes Eblen different and why our certifications matter in practice.
For every repair we do on a vehicle with ADAS, calibration requirements are assessed as part of the process. If calibration is needed, it’s done and documented before the car leaves the workshop.
We apply the same rigour to specialist vehicles. Our Tesla repairs in Adelaide include full ADAS and Autopilot sensor calibration as standard, since Tesla’s proprietary systems require approved equipment and approved technicians to calibrate correctly.
Before You Commit to a Repairer, Ask This One Question
“Does my vehicle have ADAS, and if so, will calibration be included in the repair?”
A repairer who knows what they’re doing will give you a clear answer. They’ll tell you what calibration is required, what equipment they use, and how it will be documented.
If they look blank, or say it’s not necessary, or mumble something vague, that’s your answer too.
We handle the full repair and insurance process in-house. If you want to understand how we manage insurance claims from assessment through to handover, that’s all laid out on our insurance page.
Common Questions We Get About This
Does a minor accident actually require calibration? Often, yes. The trigger is not how bad the damage looks. It’s whether the repair involved anything near a sensor, including bumper removal, windscreen work, suspension, or alignment. Even low-speed impacts can qualify.
Does insurance cover it? In most cases, yes. ADAS calibration is an OEM-required part of a complete repair on a vehicle that has those systems. A reputable insurer includes it in the claim. If a repairer isn’t including calibration in their scope of work when it’s clearly needed, the repair is technically incomplete.
How do I know if my car even has ADAS? If it was manufactured after 2018 and has automatic emergency braking, a camera behind the windscreen, parking sensors, adaptive cruise, or lane-keeping assist, it almost certainly does. Your owner’s manual will confirm it, or just ask us.
What about windscreen replacements? Yes. If your car has a forward-facing camera mounted near or to the windscreen, replacing the glass requires recalibration of that camera. This is true even if the camera itself was never touched.
The Short Version
Modern cars are genuinely safer than they used to be. But only when the systems doing the work are pointed in the right direction.
After a collision, even a small one, getting sensors properly recalibrated is not an optional extra. It’s part of returning your vehicle to the state it was in before the accident.
