ECU Master HALDEX Quick start guide
HALDEX – WIRING DIAGRAM
IMPORTANT !
1) Flyback diode for oil pump control must be conected ! Otherwise the device will fail.
2) Power ground terminal 15) should be connected with separate wire.
3) +12V must be switched power.
4) Use 3A fuse for switched +12V and 10A fuse for Oil Pump power.
5) If you use VSS input, connect pullp resistor to VSS input 10K)

Konfiguracja
Fre . Limit to turn off – the frequency on VSS input
that cause controller to set torque transfer to 0%
Fre . Limit interpolation start – the frequency of
VSS input whene the controller start to interpolate of
torque transfer.
Here is the diagram how does it work
Max oil temperature – if the temperature of Haldex module oil is greater that this parameter the
controller switch the Haldex module off, and the torque transfer is set to 0%.
Advanced settings (only for advanced users!)
Step scale – maximum number of Haldex actuator steps
Stepper motor speed – the speed of actuator
Pump ctrl. Fre uency – oil pump control PWM freqency Hz * 10)

Logged parameters
The device monitors and log the following parameters
Oil temp. - current Haldex module oil temp.,
Re . pos - required torque transfer in %
Curr. Pos – current torque transfer in %
Fre . In - frequenct on VSS input
Analog #2 – voltage on analog #2 input.
PumpDC - oil pump control Duty Cycle,
User switch – state of activation switch
