JALTEST TRAILER KIT (HARDWARE + SOFTWARE)

Jaltest Trailer Kit (Hardware + Software)

The Jaltest Trailer Kit (part 78901081, ,595) is the complete multi-brand trailer diagnostic system — hardware and one-year software license included. If your shop services trailers and needs the ability to read fault codes, perform brake system tests, calibrate height sensors, monitor refrigeration units, and access all trailer ECU systems from a single tool, the Jaltest Trailer Kit is the professional solution. This is not a basic code reader — it is dealer-level diagnostic capability across all major trailer brands and systems.

• ABS systems — full Antilock Brake System diagnostics across all major trailer ABS brands
• Refrigeration systems — Carrier and Thermo King reefer unit diagnostics including fault codes, live data, and actuation tests
• Wheel pressure control systems — TPMS and related wheel-end electronics
• Compatible trailer system brands: Bendix, Meritor, Wabco, Dana, Carrier, Thermo King, Haldex, and more

Who Needs This

Repair shops, service centers, independent technicians, and fleets that service trailers. If you are currently sending trailer ABS and reefer electrical problems to dealers or specialized trailer shops because you lack proper diagnostic capability, the Jaltest Trailer Kit pays for itself quickly. For truckload carriers, LTL operations, and trailer leasing companies with in-house maintenance, this is the tool that enables proper multi-brand trailer diagnostics without multiple OEM subscriptions.
