Jaltest PTE (Portable Trailer e-Supply) is a mobile device designed to check the power supply and the signals that are transferred between the tractor head and the towed vehicle, such as lighting, indicator lamps, and CAN communication.

It has two operating modes, depending on whether check is required in the tractor head or in the towed vehicle. In addition, Jaltest PTE can be used as external power supply in the towed vehicle, therefore it is possible to diagnose the systems with electronic control through the Jaltest diagnostic tool without tractor head.

It is a product designed to provide a quality service, reducing significantly the time spent on checks and fault detections.
