Astra H 05 1.6 TwinPort Cruise Control Wiring

[Lewis Greco]

Hello again,

Its been a while, work commitments and snow! Lovely, no doubt you were hit with it alot worse up there mind....
Anyway thought I'd come back for your thoughts on this one!
So I had a friend (Auto Electrician who owes me a favour) put a crimp on some wire etc, using 0.5 thinwall and connected up to pin 38 of the X1, I crimped a PC header on the other end and connected to the switch.

On the other leg I connected up 0.5mm thinwall to switched live from Ciggy Illuminating live, also tried live from ciggy lighter & tried live to stereo...

So connected up and checked the status of clutch switch, on all three lives shows as inactive.

Started at the switch on all three feeds, multmeter shows 14v OK,
checked continuity from switch to X1 OK
checked X1 to UEC pin as advised OK

Bit stuck with it now, from what I've read this should get me where I want to be. my only thoughts are the cable but i cant see why...

can anyone help?

I'm near to writing off the whole thing and consider it an education!

Cheers

Lewis

Anybody with ideas?

For the switched live, the switched live by the ciggy lighter doesn't work for cruise control. It's been a while but I seem to remember the power pulses which knocks off the cruise the second the switch is released.

I always take the other wire to the thick black wires around X1 connector in the footwell and never not had it work.

One thing to note is that opcom doesn't always pick up the stalk and clutch switch operation, not even the licenced one does properly so I normally check with Tech2

OK,

Well I'll try with the wire as suggested, seems abit weird as I cant see anybody else with this issue online ? Do you know which pin this wire connects to?

If I still have no joy then I think I'll keep an eye out for someone local to Sussex who can check with tech2.

TBH there aren't that many people who retrofit the wire themselves. There are 2 levels of switched live in the Astra H which turn off at different times.

Ciggy one didn't work with me, nor has it with a couple of people who have contacted me.

Any black wire will do, it isn't taking a load at all it is just registering 12v at the UEC. You have to splice it as there is no where to add a pin free, if you unpick a factory loom it is spliced in loads of places.

OK,

I'll try and tap it off one of these black lives and see what the outcome is tomorrow eve, just wanted to wire in loose to the top of the plug to test.

I'll let you know how I get on !

Thanks

Evening,

Well I've been out in the Garage again today, tried all of the black wires at the X1 but still the switch is not showing Active!
When using a multi-metre to bridge the 2 wires it read 14.23-14.25 volts, same as when switch is connected up.

So now I'm really at a loss, I've confirmed the connections all the way back to the UEC. Cant understand what else it could be, I know its unlikely but would there be a fuse in the UEC?

Otherwise I'm thinking it could be the firmware on the ECU, think the freeze date is original release. gonna look for anyone else with same symptoms haven't come across any so far though

Any other ideas?

Cheers

Lou
