Jaltest PTE plugs in between a truck and trailer and checks the power and every signal passing between them: lights, indicators and CAN communication.

Use it in truck mode or trailer mode, depending on which end you're testing. It can also power the trailer on its own, so you can diagnose the trailer's electronic systems with your Jaltest kit without a truck hooked up.

LEDs show the state of each signal on the ISO 7638 and ISO 12098 connectors at a glance, for a fast, safe check.
