Once DIAG++ version 3 is launched and connected to a valid SUMS account, data is exchanged automatically between the trailer’s EBS and the SUMS portal. This ensures:

Automatic Updates
DIAG++ V3 will fully facilitate application software updates when available when EBS valves are connected.
Compliance with R156
DIAG++ V3 collects information on updates, helping workshops to maintain compliance once the operator has collected trailer information.
Offline Mode
Details of configuration and software updates will be exportable for upload from another device with an internet connection.
Configuration Lock
Type Approval relevant settings will not be editable once a ECU is ‘locked’. Locking is effevtive after end-of-line test through DIAG++ V3 or automatically after vehicle has travelled 500 km (already in place since version A847 on EBS and ABS 4.0).
