ADAS Best Recommended PracticesPresented by: Bob Pattengale

Technology Evolution – Honda Example• LaneWatch (LW) – 2012 Camera in passenger mirror

• Adaptive Cruise Control (ACC) 2013• Forward Collision Warning (FCW) 2013• Lane Departure Warning (LDW) 2013• Auto High-Beam (AHB) 2013 Multipurpose camera Millimeter wave radar

• Collision Mitigation Brake System (CMBS) 2016• Lane Keeping Assist System (LKAS) 2016• Road Departure Mitigation (RDM) 2016 Improved camera and radar technology

• Blind Spot Information (BSI) 2018• Cross Traffic Monitor (CTM) 2018 Radar added to back of vehicle

ADAS Calibration Strategies• Dynamic calibration with scan tool interaction

• Chrysler, BMW, Honda Odyssey, etc• Prep vehicle according to recommendations, enter dynamic

calibration mode using a scan tool and drive until complete.

ADAS Calibration Strategies• Static calibration with scan tool interaction

• VW, Honda, Toyota, etc.• Prep vehicle according to recommendations, including setting

targets. Use the scan tool to finalize the calibration.

ADAS Calibration Strategies• Mechanical aiming check without scan tool

• Example Honda Accord• Prep vehicle according to recommendations. Measurement

determines accuracy.

Best Recommended Practices• Review the customer issue.

• Vehicle not operating as expected• Collision repair follow-up• Components removed for vehicle service

• Can the issue be duplicated?• Proper road test required to duplicate.

• What portion of the system is effected?• Physical damage/calibration• Electrical damaged wiring, opens, shorts, etc.• Networking issue

• Research the system, TSBs, reprogramming, etc.• Develop a diagnostic/calibration plan.• Do you have the tools required for the job?• Execute the diagnostic/calibration plan.• Documentation – Legal Implications?

Identify the Technology• Service information is not always accurate for year, make and

model. • VIN number does not provide ADAS equipment information. • Visual inspection:

• Check the windshield for camera• Check the front of the vehicle for radar• Check the mirrors for images• Check the instrument cluster for messages

Identify the Equipment• Perform a module scan on the vehicle.

Review Service Information• Aftermarket service information might offer limited support for

ADAS systems. • OE websites are available with latest information.

• www.nastf.org

Review Service Information• Honda factory website - $10 for 72 hours

Review Service Information• Review aiming instructions and tools required.

Review Service Information• Technical service bulletins

• DTC B18DA or B1EDA After BSI Radar Unit Replacement• B18DA (L/S different s/w version from right)• B1EDA (R/S different s/w version from left)

Review Service Bay Dimensions• Check floor level must be within 1⁰ degree front and back, right

and left. • Honda example floor dimensions:

LaneWatch

Blind Spot

Radar and Cameras

Review Tools Required for Service• Don’t assume all models are the same.• Honda Accord from 2013 to present:

• Millimeter wave radar• 3 options for location, alignment and tools.

Check Scan Tool Capabilities• OE vs. Aftermarket?

Vehicle Set-up for Calibration• Honda BSI radar example:

• Clean the surface of the BSI radar unit.• Check for aftermarket suspension modifications.• Verify the tires are the correct size and set pressures to the

specifications shown on the doorjamb label.• Make sure the fuel tank is full.

Vehicle Set-up for Calibration (cont.)• Honda BSI radar example:

• Remove all cargo from the vehicle except the spare tire and tool kit.

• Park the vehicle on level ground (within 1⁰ degree) with at least 4 m (13.1 ft) of space on both sides and behind the vehicle. Do not do this procedure with the vehicle on a lift or with the tires on steel plates or rollers.

• Verify the steering wheel is pointed straight ahead.• Shift the transmission into P and apply the parking brake.

Set-up for Calibration• Perform vehicle measurements according to OE recommendations. • Most begin with finding the centerline of the vehicle and locating

additional markers for setting targets.

Set-up for Calibration• Many options are described for finding and locating measurement

points. • Plumb bob and string• Lasers• Jigs

Set-up for Calibration• Centerline can be found with laser

Set-up for Calibration• Lasers with distance measurement can also be useful.

Set-up for Calibration• The next step is usually measuring and marking the distance

from the vehicle to specified target.

Set-up for Calibration• Prepping and locating the targets

Set-up for Calibration• Blind spot radar – Honda example
