DIAG++
Operator‘s Guide
Introduction
With DIAG++ you can use a standard personal computer to read and delete diagnostic codes, program vehicle
parameters and end of line test (EOLT) for Haldex EB+ 4.0 EBS (referred as EBS in the rest of the document). The
USB PC Interface (dongle) allows communications between a standard PC and the EBS ECU. Connections to the
USB PC Interface (dongle) are made through a cable connecting to a USB port on the computer and another
cable connecting the diagnostic interface to the ECU. The vehicle parameter data is stored inside the ECU. It will
remain intact even after electrical power is removed from the EBS.
Note: The USB PC Interface (dongle) is different to the RS232 interface pods as used on earlier systems.
