BMW ADAS CALIBRATION

Connecting the BMW ISTA (Integrated Service Technical Application) to read and clear all stored fault codes.

Inspecting the windshield-mounted stereo camera housing and front radar unit for physical damage or displacement.

Verifying correct tyre pressures to maintain accurate ride height during the calibration process.

Confirming the steering angle sensor is at the centre, and the vehicle is on a level, consistent surface.

Ensuring the vehicle is at standard kerb weight and has a minimum of half a tank of fuel.

The BMW is positioned indoors in a space built to meet BMW's exact dimensional specifications.

BMW-specified target boards are placed at exact distances and heights relative to the front camera.

BMW ISTA software connects via the OBD-II interface to initiate the reset sequence.

The stereo camera's focal geometry is recalibrated to the vehicle's centre axis.

The vehicle is driven on clearly marked roads at consistent speeds, typically between 50 and 100 km/h.

The Driving Assistant software re-learns lane boundaries, object tracking distances, and sign recognition.

System verification covers: Active Cruise Control object acquisition, Lane Departure Warning sensitivity, and Traffic Sign Recognition accuracy.

Stereo Forward Camera (Windshield)

Targets reset the camera's pitch, yaw, and roll alignment to BMW factory parameters.

Ensures the correct functioning of Pedestrian Detection and Traffic Sign Recognition.

Followed by a dynamic road validation to confirm lane-centring performance.

Front Radar Unit (Lower Grille)

Beam angle verified with a laser frame to sit flush and level with the road plane.

This alignment is essential for accurate Automatic Emergency Braking trigger timing.

Recalibrated so Active Cruise Control tracks the correct lead vehicle at the correct distance.

Side Radar Sensors (Door Sills / Rear Bumper)

Sensors are calibrated for accurate Lane Change Warning and Blind Spot Detection.

Rear cross-traffic alerts are verified for correct zone coverage and trigger sensitivity.

Surround View Cameras (360-degree)

Multi-camera stitching is realigned for a seamless overhead parking image.

Parking guidance overlays are confirmed to accurately represent vehicle dimensions.

A full re-scan via BMW ISTA to confirm zero active fault codes remain.

A real-world road validation to confirm Active Cruise Control and Lane Keeping Assist response.

Digital logging of all calibration data, timestamps, and technician records.

Issuing a formal compliance certificate for the vehicle owner's records, insurance, and warranty purposes.
