Haldex EB+ Gen 2 - System Diagnostics and Information; Diagnostic Communication; EB+ Gen 2 Info Centre Features; Diagnostic Testing Capabilities

An important feature of the EB+ Gen 2 system is that it provides an
extensive on board diagnostic capability. The system displays a range
of codes, which allow rapid diagnosis of the problem should one
occur.
Diagnostic communication is in accordance to ISO11898 using
Keyword (KWP2000) protocol and is accessed by either the ISO7638
- 7 pin connector which uses pin 6 and 7 as a CAN data bus using
ISO Interface Assembly (815 018 001) or optional side-of-vehicle
connector or directly to ECU (Fig 7). Any suitable device connected to
this CAN data bus may read diagnostic information.
An EB+ Gen 2 Info Centre can be connected permanently to the
ECU's diagnostic 'DIAG' connection. While the ECU is powered
information is transferred to the Info Centre's memory, which can
be recalled. Power is supplied from the vehicle system via the ECU
diagnostics connector.
