Description
- This standard cable can be used either for an output or an input.
- Conforms to IP67 when mated with 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.

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 | Measured value | Comments |
|
1 - 2 Red - Black
Only for Gen3 Twin AUX : 3 - 2 Yellow - Black |
Output is ON |
B+ |
If the measured value is below B+, it can indicate a resistance in the wiring. Next steps :

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 :

|---|---|---|---|---|
| Test points | Condition | Required value | Mesured value | Comments |

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 :

Input signal |
In general, switching voltage is 0V to 5V analogic (sensor), up to B+ (switch) For General Purpose Input use, the switching voltage depends of the configuration, and need to be checked in ECU setup Next steps :
