Truck & Off-Highway Diagnostic
Haldex Diag+ is the diagnostic software from Haldex for their trailer braking systems, principally trailer EBS (electronic braking system) and ABS control units. Running on Windows with a Haldex or RP1210/USB diagnostic interface, it reads and clears trailer-brake fault codes, displays live data such as wheel speeds, load and pressure signals, and valve status, runs actuator and lamp tests, and handles ECU parameterization, configuration, and end-of-line setup. Trailer builders and workshops use it to commission new trailer EBS units, configure axle and load parameters, diagnose ABS faults, and produce service reports. Diag+ is a system-specific diagnostic and configuration utility for trailer braking, not an engine-management, tuning, or car-diagnostic tool.
Haldex Diag+ addresses trailer braking, fully outside Softechpro's engine-file scope; Softechpro's DPF/EGR/AdBlue/DTC-off editing and checksum correction complement it without any functional overlap.
