Cruise Control to European Aveo

Do you have any clue of what I should do next?

Try this and learn how to use the tool and go back to my comment on what to measure.

Okay I will watch it and apply it to your last comment.

Thank you very much xintersecty!

I just opened the switch itself and this is how it looks like from the inside.

I believe it may help.


As you said before, it seems it's a ground activated switch.
Pin 1 is for V_IN and pin 4 is Ground. No idea about pin 2 and 3. Guess one of them is light but don't know about the other one.

2 pins are the signals, the other is ground and dimmer light.
Electrical hacking 101
1) turn on car
2) measure voltage of each wire to ground, record the color and voltage
3) turn on the lights and repeat each step, this should find the lighting circuit.
4) turn off the lights
5) if the wire measures zero to ground then that might be ground
6) if the wire measures a positive voltage to ground that could be the signal.

Do you have a wiring schematic?

By any chance do you have wiring schematics for my car?

Its 2011 Aveo

Correct me if im wrong: what you are advising me is to first find the ground wire, and then try every positive voltage wire till it works?

I measured the connector above my accelerator pedal with the car running (I disconnected the connector from the female) and this were my results:



As you can see, noone was 0 volts. No ground on that connector?

Any advise?

I read on another post that you could tap directly into the ECU. How would I do that?

Is this the ECU?

Anyone can help me?

Anyone has any clue?

Is your car drive-by-wire or you have a throttle cable? If it is a cable system, how did you connected the throttle plate actuator? As far as I know, the only european drive-by-wire systems were 1,2 aveos.
