Calibration Explained

Why ADAS Calibration Matters

Modern driver-assistance systems depend on precisely positioned sensors. Calibration restores those sensors to the manufacturer's specification, so safety features such as ACC, AEB, lane keeping and auto park work exactly as designed.

ADAS Explained

What Are Advanced Driver-Assistance Systems?

ADAS uses cameras, radar and LiDAR to read the road around your vehicle and support you while driving. These systems help prevent collisions and reduce driver workload — but they only work correctly when every sensor is aligned to the vehicle manufacturer's specification. Even a fraction of a degree of misalignment can shift detection zones, delay warnings or trigger false alerts.

Adaptive Cruise Control (ACC)Maintains a safe following distance by adjusting vehicle speed automatically.
Automatic Emergency Braking (AEB)Applies the brakes when a collision is imminent and the driver does not react.
Lane Keeping / Departure (LKA / LDW)Monitors lane markings and warns or steers to keep the vehicle in lane.
Blind Spot Monitoring (BSM)Detects vehicles in blind spots and alerts before lane changes.
Forward Collision Warning (FCW)Warns of an imminent collision with a vehicle or obstacle ahead.
Traffic Sign Recognition (TSR)Reads speed and road signs to inform the driver and the system.
When It's Required

When Does Your Vehicle Need Calibration?

Any repair or replacement that disturbs a sensor's mounting position or the vehicle's geometry can take ADAS out of specification.

Windshield ReplacementThe forward camera is mounted behind the glass — removing the windshield disturbs its reference point.
Collision or Bumper RepairBumper, grille or quarter-panel work shifts front and corner radar aim.
Suspension or Ride-Height ChangeNew springs, struts or ride-height changes alter sensor angles relative to the road.
Sensor or Module ReplacementA new camera, radar or control module arrives unaligned and must be learned by the vehicle.
Wheel Alignment / Tire ChangeAlignment or tire size changes affect the vehicle's thrust line and sensor reference.
Warning Light or False AlertsAn ADAS warning lamp, phantom braking or inactive features often mean calibration is required.
Why RELINE

Why Choose RELINE

We treat every calibration as a delivery standard — measured by equipment and data.

01

OEM-Spec Execution

We follow each brand's factory calibration procedure and target requirements — no generic shortcuts — so results stay accurate and repeatable.

02

Professional Diagnostic Equipment

Dedicated radar, camera and LiDAR calibration targets and diagnostic tools, covering multiple brands and protocols.

03

Fully Traceable Data

Every vehicle receives its own calibration record and report, with parameters retained for your archive and future comparison.

04

End-to-End Verification

After calibration we run system self-checks and road-test verification, and hand the car back only once systems are confirmed normal.

Calibration Process

Our Calibration Process

From intake to delivery, every step follows a defined standard and is documented.

Step 01

Intake Inspection

Read fault codes and sensor status to confirm whether calibration, installation misalignment or system anomalies are present.

Step 02

Diagnosis & Assessment

Check OEM specifications and vehicle configuration, then determine target type, workstation and parameter requirements to define the calibration plan.

Step 03

Calibration Execution

Set up targets and equipment per specification and align angles, height and coordinates for radar, LiDAR and cameras.

Step 04

Functional Verification

Run system self-checks and road-test verification to confirm ACC, AEB, lane keeping and auto park are fully restored.

Step 05

Report & Handover

Compile calibration data and results, hand over a line-by-line report, and retain records for future reference.

FAQ

Frequently Asked Questions

Plain-English answers to the questions we hear most from drivers and shops.

When does my vehicle need ADAS calibration?
After windshield replacement, front or rear bumper work, collision repair, suspension or ride-height changes, wheel alignment, sensor or module replacement — or whenever an ADAS warning light appears. If in doubt, a diagnostic scan will confirm.
Why can't the warning light just be cleared?
Clearing a code removes the message without fixing the underlying aim. An out-of-spec sensor can still detect late, trigger false alerts or fail to activate at all. Calibration restores the system to manufacturer specification — that is what makes clearing the warning legitimate.
Static or dynamic — what's the difference?
Static calibration is performed in the workshop with OEM-specification targets placed at measured distances and heights. Dynamic calibration is completed on the road over a defined drive cycle. Some vehicles require one, some the other, and some both — the manufacturer's procedure decides.
How long does calibration take?
A single sensor typically takes one to two hours including pre-scan and verification. Multi-sensor jobs and dynamic drive cycles take longer. We confirm a realistic time window for your vehicle at booking.
Do I receive documentation?
Yes. Every calibration is completed with a line-by-line report documenting the pre-scan, procedure, results and post-verification — useful for insurance files and service records.
How much does calibration cost?
Rates are listed on our pricing page in CAD per service and include standard labour. The exact scope is confirmed at intake based on the vehicle and the systems affected.
