Auxiliary Operation - Haldex DIAG++ Operator's Manual

Operator's Guide

Auxiliary operation

Auxiliary operations are dependant on the installed EBS product.
EB+ 4.0 has up to 4 usable Premium auxiliary connectors (AUX 0-3), 2 usable Standard auxiliary connectors (AUX
4 & 5) and a Super AUX, which can be configured using the DIAG++ software.
This amount of inputs and outputs are sufficient for most used standard trailer applications. In the case of
malfunction (short circuit / open circuit) the EB+ 4.0 system generates a DTC code and the service lamp will be
triggered after start up.

O/P (AUX 0-3) – Switched supply voltage outputs on red channel (pin 1) and yellow channel (pin3) with 1.2A
maximum supply current for each channel.
Dig I/ P (AUX 0) - Digital monitor input. Both red channel (pin 1) and yellow channel (pin 3) can be used to
monitor a state of change input (B+ or B-)
Dig I/P (AUX 0-3) – Digital monitor input. Red channel (pin 1) can be used to monitor a state change input (B+ or
B-)
Ana I/P (AUX 1-3) – Analogue input on yellow channel (pin 3) can be used to measure voltage input.
Ana I/P (AUX 4 & 5) – Analogue input. Analogue input (pin 3) between 0 and 5V.
5 volt (AUX 4 & 5) – 5 volt switched output on pin1. Combined supply current from AUX 4 and AUX 5 (pins 1)
