Engine random cut out

[Jimmysan 0]

So spent hours last night with a friend that's got some experience with fault finding. Concluded that the immobiliser is a prime suspect, It's a Clifford concept 300, but could well be the factory immobiliser?

 

Could not get the dash lights on all night, so this problem has got worse over time.

 

At the point of giving up now and taking it to an auto electrician, really don't want to pay out though because I'm selling it in a week!

 

Any help with immobilisers, I can't locate the box for a start?

 

Don't think it is ignition switch but could be wrong, never have intermittent lighting etc

The box for my clifford is in the engine bay, bolted to the bulkhead at the top right. You need a master key to get in

Could be the same then, is it beneath the alarm siren which is bolted behind the battery? Hmm master key, any bodge to get it open?

Anybody any advice on how to test the factory system; reader coil etc?

Would the factory immob show up on vag-com? Saying that something else could show up on it and help?

Good point, not had any related codes when I scanned it.

 

The fact that the indicators cut the engine points to the Clifford as thats wired to the indicators

Yeah. The factory imob will show up on vag com.

I have all the diagnostic software for clifford alarm. Could it be in valet mode or something?

Fault codes recorded last night:

 

00668 - Supply Voltage Terminal 30 

00532 - Supply Voltage B+

 

The problem has got worse and I'm getting the dash lights on once then if it locks out I have to wait overnight to get the dash lights on again (I've tried another battery so don't think it's that)

 

Planning to change the ignition switch tonight, not hopeful it will fix it but thinking it's worth a try before I take it in to a garage?

I know the ignition switch can cause issues with starting but l have not heard of it cutting an engine buddy, however as it is cheap and pretty easy it is worth a try.

 

after a quick search l would say after trying a new battery you prob have a wiring issue somewhere dude.

Did you clear any codes after if you disconnected the battery and those codes came back again? Cos you can get them just from taking the terminal clamps off.

Pulled the fuse box down last night. Found the power supply for the clifford system clipped into a connector behind the fuses, (it pulled free when I dropped the fusebox so suspected loose connection but this is not the problem, still cutting out when indicate) 

 

But still couldn't see the clifford box, the black and brown cables seem to go right to the back of the footwell?

 

The conlog box (guessing this is the transponder?) is there just hanging loose with it's wires cut,

 

Only other thing that looked suspicious was a single small brown wire coming up through the footwell just past the fuse number 1, I can't work out where this has broken from.

anybody know likely places to find the clifford control unit, behind glovebox or above fusebox?

[Jimmysan 0]

Just to note, the factory immob is bypassed (assumed by the fact that all wiring from the conlog box is cut)

 

Pretty sure my problem lies with the immobiliser, just can't find the control unit

[VR6Pete 1,455]

Mmmm sounds like it's been badly fitted! I had a single wire that had cut as it was fitted so bloody tightly! It controlled the central locking pump which I was having issues with my full closure.

I'll try and get the wiring diagram for the concept 300 and you can then see what the brown wire is for.

I know that the concept is usually hooked up to the indicators to indicate armed / disarmed so could be something not wired up properly! But sounds suspect just having a random wire there!

Aha, I've found this http://www.eserviceinfo.com/preview/Clifford.Concept.300.Wiring.gif

 

thanks Pete for the pointer, indicator feed is brown!

 

sounds promising! Will report back after trying to sort this tonight

 

Thanks

Pulled the clifford box out, won't go into detail but I've bypassed the immob and car is cured. Got to decide what to do know, don't want the immob/alarm but then I'd loose remote locking?

 

I can't work out where the loose brown cable goes, traced other end back to the earth point for the fuse box on the door pillar, but seems like an add-on
