Cojali leaps into future with Jaltest AR
Augmented reality has been slowly creeping into the vehicle repair space for several years, with OEMs such as Caterpillar using it for inspections and Peterbilt for electrical wiring diagrams. Penske has even used the Microsoft HoloLens 2 for brake installation training. Now diagnostic provider Cojali USA has jumped into the AR ring by pairing its Jaltest troubleshooting software with the Magic Leap 2 smart goggles.
Jaltest Diagnostics AR, expected to arrive in shops in 2026, allows users to interact with electronic units, technical data, and real-time assistance without interrupting the job at hand or requiring any back-and-forth between a computer and a vehicle. The technician instead uses hand gestures to manipulate the interface seen through the glasses.
The company has been developing the project since 20222 and revealed the product in Nashville at the American Trucking Associations' 2025 Technology & Maintenance Council Annual Meeting, where Christian Palomanes, Cojali director of OEM sales North America, demoed the product for Fleet Maintenance.
"We're going to be able to reduce downtime," Palomanes explained. "[Technicians] don't need to be going to a computer and then moving to a truck. They're going to have the truck in front of them, and they're going to be able to do the diagnostics in [the goggles]."
The software fills in the gap between on-screen diagnostics and hands-on troubleshooting, bringing fault codes and technical data directly into a technician's field of view. The mixed-reality glasses are fully customizable, allowing them to be tailored for repair bays, end-of-line testing, training programs, and more.
"Jaltest AR is just the first milestone of a very ambitious project," Palomanes noted, explaining that the product is still in phase one of development. In phase 2, Cojali plans to roll out Jaltest VC, an update to the software that uses voice command technology to allow for fully hands-free operation, similar to what RealWear does with their wearable headsets.
The final phase, which the company hopes will be complete in three years, is to incorporate the use of AI for more advanced troubleshooting.
