DIN to Aux

Finden Sie hier eine erweiterte Beschreibung, die Steckerbelegung und Hilfe zur Diagnose!

Beschreibung

  • Possible applications :
    • COLAS
    • Ilas-E
    • Mechanical Height Sensor
    • 3/2 valve
  • Conforms to IP67 when mated with plug DIN 72585 style connector and ECU auxiliary socket
  • Cable insulation material : PVC
  • Use tag to identify the auxiliary position :

Identification tags are incorporated on either side of the auxiliary connector. These must be removed to identify the appropriate usage before connecting into the ECU.

Diagnose

The Auxiliary cable can have multiple applications. It can be used for an output (ILAS-E, COLAS, ...) or for an input (Pressure sensor , switch, ...)

Depending the use, Input or Output, the voltage and the way to check is changing

OUTPUT AUX
Test points Condition Required value Mesured value Comments

1 - 2

Red - Black

 

Only for Gen3 Twin AUX :

3 - 2

Yellow - Black

Output is ON

B+

  

If the mesured value is below B+, it can indicate a resistance in the wiring.

Next steps :

  • check for oxidation marks in the connectors
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)
  • check the solenoid (Colas, Ilas-E, ...)

1 - 2

Red - Black

 

Only for Gen3 Twin AUX :

 3 - 2

Yellow - Black

Output is OFF

5V (detection voltage)

  

The ECU use this low voltage to determine if a load (solenoid) is connected or not.

Next steps :

  • check for oxidation marks in the connectors
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)

 

INPUT AUX
Test points Condition Required value Mesured value Comments

1 - 2

Red - Black

Power ON

 5V  

Never connect the black wire to the vehicle's ground !

This 5V must only be used for a switch or sensor power

Next steps :

  • check for oxidation marks in the connectors
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)

3 - 2

Yellow - Black

Input signal

  

In general, switching voltage is 0V to 5V analogic (sensor), up to B+ (switch)

For General Purpose Input use, the switching voltage depend of the configuration, and need to be checked in ECU setup

Next steps :

  • check for oxidation marks in the connectors
  • check the switch or sensor connected
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)
