Thatcham releases long-awaited ADAS repair requirements

Published:  31 July, 2020

 The long-awaited requirements for the safe repair of ADAS-equipped vehicles have been published today (Friday 31 July) by Thatcham Research.

The Insurance Industry Requirements (IIR) come as the number of ADAS-enabled vehicles on UK roads reaches 4.5 million, a figure that is set to continue growing exponentially.

The IIR confirms that inspection, realignment and calibration requirements must be considered in all situations where ADAS sensors, parts likely to affect the operation and functionality of ADAS sensors or vehicle geometry is included within the repair, service or maintenance procedure.

The requirements establish the key steps repairers must follow to ensure that ADAS continue to function as they did pre-accident. This includes Identifying the presence, or not, of ADAS on the vehicle and ensuring this is recorded, and ccompleting all relevant inspection, realignment and calibration activities as detailed within the repair procedures. Lastly, repairers must ensure that calibration results confirm that the sensors are functioning within the vehicle manufacturer’s technical specification.

In addition, repair procedures should clearly identify if inspection, realignment and calibration are required and why. Repairs must be then be carried out by a ‘currently competent person’. Finally. fully verifiable and auditable records should be produced, with a copy provided to the Asset Owner or Work Provider.

Richard Billyeald, Chief Technical Officer, Thatcham Research commented: “The correct procedures for the safe repair of vehicles with ADAS, and in what scenarios calibration of the systems themselves is required, has been a long-standing challenge to the automotive repair industry. Today the IIR brings clarity to repairers and enables the long-term sustainability of ADAS-equipped vehicles.

Dean Lander, Head of Repair Sector Services, Thatcham Research observed: “As features like autonomous emergency braking and lane keeping systems become more and more common, continuing with a disparate approach to ADAS repair is at best inefficient and at worst a threat to road safety. The IIR will deliver clarity to bodyshops who need a standardised approach to repairing ADAS. The goal is for ADAS reinstatement to become business as usual, presenting no greater challenge than fitting a new wheel.”

Commenting on the release of the IIRR, IMI CEO Steve Nash said: “Both the ADAS Guidance and Insurance Industry Requirements for ADAS align to the IMI belief that, it is of paramount importance to enable the sector to deliver on its obligation for safe repair and in addition to build trust with consumers.  Furthermore, both initiatives align to the IMI Campaigns for Change and TechSafe initiatives, which provide clarity for all stakeholders with an interest in ensuring competence during vehicle maintenance and repair activities, including ADAS."

Neil Atherton, Sales and Marketing Director at Autoglass, observed: “At Autoglass, we welcome and embrace the launch of the IIR. We have been concerned about varying standards in ADAS recalibration across the after-market for some time now. We have worked on numerous initiatives to raise standards for the benefit of all and give confidence that vehicles are being returned to the road in a safe condition, for example partnering with the IMI on the creation of the first industry training accreditation for recalibration.  

Neil Hilton, Head of HGS, Hella Gutman added: “Following the rapid increase in vehicle ADAS fitment it is paramount that the automotive industry has a unilateral approach to the repair and calibration of these vehicles, as pioneers of aftermarket ADAS calibration equipment and a long-standing relationship working with Thatcham Research in this area, it is great news that we finally have the IIR to facilitate safe and accurate working practices on ADAS vehicles.”
