Does modern car tech need servicing?
Hi-tech advanced driver assistance systems (ADAS) have added an extra layer of safety to motoring, but do these devices need to be serviced?
Introduced in the 1970s, the anti-lock braking system (ABS) is considered the first advanced driver assistance system.
By preventing brake lock-up, ABS allows drivers to maintain vehicle control under heavy braking. It was – and remains – an automotive game changer.
Since then, the development of high-tech motoring devices has increased exponentially. Modern cars are now bristling with cameras, sensors, lasers and all sorts of gadgets to make driving safer and easier.
Systems include adaptive cruise control, rear cross-traffic alert, parking assist, and autonomous emergency braking (AEB). AEB detects an imminent head-on crash with other objects, cyclists and pedestrians, and automatically applies the brakes to avoid a collision.
Some of this tech has proved so beneficial to road safety, its use has been enshrined in law.
Just like ABS became mandatory in 2003 for all new cars sold in Australia, AEB must be fitted to all new cars sold from March 2025.
So, once these devices have been installed in a vehicle, do they need to be maintained?
Does car tech need to be serviced?
The Australian Automotive Aftermarket Association (AAAA) represents the automotive service and repair industry, including vehicle workshops, tool and equipment makers, and training organisations.
Following consultation with industry experts, AAAA produced the ADAS –industry code of conduct, which has identified several situations where an ADAS device may need to be recalibrated.
Windscreen replacement
Some ADAS cameras and sensors are attached to the windscreen, and windscreen replacement can affect their alignment.
Steering, wheel alignment and suspension work
Adjustments to steering or suspension may affect the relative position of cameras and sensors in relation to the road.
After a crash
Even a minor vehicle crash could damage cameras and sensors or affect their alignment. If they’re removed and refitted during a repair they may need to be recalibrated.
Following modifications
Fitting accessories like bull bars and extra driving lights can affect the operation of some systems.
Vehicle maker’s guidelines
Some vehicle manufacturers may recommend checking ADAS calibration during a vehicle’s regular maintenance.
Poor ADAS function
If you notice a system isn’t working, or is operating erratically, it may need recalibration.
ADAS calibration requires system knowledge and specialised diagnostic tools and equipment, which can differ between vehicle makers.
Your vehicle technician should advise you if ADAS calibration is needed.
