MOT testers help please
Hi guys, long time no see. hope all are well, I have a little one fit to burst from his mother right now so wish me luck!
Anyway the reason for the post is it has occurred to me that my mk focus 1.8 petrol may fail its MOT this year after new rules from Europe.
A little background to car: its an 03 plate car that I bought nearly 6 years ago as a Cat D write off that had been repaired. At the time of repair
300mm front rotars were fitted to the front and the ABS was disconnected.
I have as far as I can work out an ABS light, seat belt pretensioner, airbag and possibly a power steering light which don't light during the
test sequence at ignition.
After an initial search it seems the seat belt pretensioner/airbag could possibly be solved by cleaning the contacts of the wiring under the drivers
seat. Obviously the ABS light won't be sorted unless it works, but as ABS was fitted as an option, I was wondering if a neat extraction of the
ABS wiring and a claim it was never fitted might bypass that one. I could check the bulbs for the others and go for an early MOT/ bite the bullet and
get it all properly looked at...
are warning lights ever fitted to cars without the item, as an attempt at cost saving by manufacturing one unit?
any help or advice appreciated.
Ed.

I'd imagine the dashboard is a single unit across the board, along with the bulb fittings.. But without the wiring behind it

I don't know whether it applies to Ford, but the various options are sometimes enabled and disabled in the ECU. So the same ECU can be used for
multiple versions of the car with different kit.
I only remember it because I know some people have swapped their airbag/pretensioner equipped seats for Sparco or similar, and simply disabled the
relevant setting in the ECU. but my background is VW rather than Ford.

If the lights there but doesn't come on during ignition sequence its a fail as I understand it

It would probably be easier to arrange a feed to the abs light to make it come on with the oil or charging light and hope that the tester does not
realise its not operating for the correct time and sequence, not that I would do such a thing.

ABS only became a compulsory fitment from 2007 onwards so if you remove any trace that the vehicle once had ABS (much easier said than done) I think
you should be OK. All the ABS plumbing and the ABS unit must be removed and the wiring adjusted accordingly

There has got to be a market for a little black box to drive these lights......

Problem with is if you do that somebody gets in to drive the car will then assume it has working ABS and then proceeds to have a big accident,
all the ingredient for insurance company not paying out and law suits flying in all directions.

Thanks for the input, the notion of rewiring the abs light had occured... But then i'd have to replace the wiring to make it look like it did
something...
If I did claim it never had ABS, I wondered how close they would look, and how obvious it would be...
guess if its plumbed in to the brake lines its gonna be a right pain to take it all out.
third option I guess to actually get it working again, the front suspension was replaced at repair, which included front uprights, with bigger discs
and calipers from a st170 so i don't know how much work that would be assuming it would be compatible with the ABS hard wear thats installed.
Any further thoughts gratefully received.

forgive my possible stupid question but why was the ABS disabled due to fitting of bigger discs?
Can it not just re-switched back on for the MOT?

I don't know why it was disabled, I assume it has something to do with uprights from an st170, tbh I was a bit of a pup when i bought it and
didn't look too close.
literally the wires have been cut so i don't know why it wasn't reattached, does make me a bit nervous about the quality of the rest of
it - i.e is there any air bags in the thing!
I assume ABS is activated by a sensor in the hub?

further thoughts, I suspect the ABS wiring is related to the caliper and hub from the st170. and my MP3 model was never fitted with it. How do I tell
?
if it wasn't fitted that leaves me with a seat belt pretensioner light and the ! in the cog seen above the engine warning light.
The 2nd airbag light with the line through it doesn't seem to have an LED...
The traction control light above doesn't work, but that wouldn't be installed if I don't have ABS...
