Total Control Over the Towed Unit
Trailer diagnostics present a unique challenge: they rely on the tractor head for power and data via the ISO 7638 (7-pin) connector. The Jaltest Trailer Kit—especially when paired with the optional Jaltest PTE (Portable Trailer e-Supply)—allows you to power the trailer’s electronic systems independently. This means you can diagnose a “dead” trailer in the yard or conduct a full EBS check before the driver even hitches up.
Key Technical Pillars & Semantic Entities:
-
EBS/ABS Mastery: Full support for all generations of electronic braking systems, including Wabco (VCS, TEBS), Knorr-Bremse (TEBS G2), and Haldex (EB+). It is one of the few aftermarket tools capable of performing the mandatory End-of-Line (EoL) calibrations after a module replacement.
-
System Display & Real-Time Data: View live pneumatic and electrical schematics on-screen. You can watch brake pressure values change in real-time as you actuate the system, allowing you to find leaks or sticking valves instantly.
-
Expert Mode Programming: Granting you the ability to copy and paste parameters between ECUs, modify suspension ride heights, and configure auxiliary inputs for specialized trailer equipment.
-
Refrigeration & Cooling: Includes deep-level diagnostics for Thermo King and Carrier refrigeration units, allowing you to check engine status, clear codes, and monitor temperature setpoints.
-
Jaltest Info (Technical Library): Provides interactive wiring diagrams where components are highlighted based on the selected fault. It also includes “System Technical Data” like tightening torques for wheel hubs and brake caliper reference measurements.
