Portable Trailer E-Supply (Unit Only)

Check all of your trailer lights and cables – power up your trailer without a tractor unit.

Jaltest PTE is a portable device designed to verify the electrical signals that are transferred from the tractor unit to the trailer. This includes lights, indicators and CAN communication.

Jaltest PTE has two modes of operation, dependant on the vehicle where verification is required. Using an intuitive LED interface the device marks the status of each signal. Therefore, significantly reducing the time spent on inspection and fault detection.

Jaltest PTE performs checks without the need of an external power supply, thus allowing for quick failure detection making it a great compliment to the main Jaltest Diagnostics tool.
