Diagnostic

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, ...)

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)

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)

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)
