Potential 07 KJ purchase, ABS/ speed sensor query

[toyracer]

Hi Everyone,
I'm new to the forum, looking for a KJ in Doha (Qatar, Middle East). Vehicle choice here is limited, and condition generally atrocious, so I'm willing to put up with more problems than I would back home in the UK when buying. It is worth accepting some maintenance work - I'm reasonably handy with a set of spanners and enjoy getting stuck in.

So - I viewed a 2007 KJ Classic today with a few faults. Bodywise the car was in good condition compared to others I have seen, likewise the engine and ****** from my short test. Priced the same as bodily tatty and ruined interior vehicles, and that's before you get them started up. Good used vehicles are very hard to find here.

However, the main faults - which I'm hoping you can offer some opinions on:

1. Speedometer / mileometer not working (no idea therefore on actual mileage, guess 50k from brake disc wear and fairly unworn interior).
2. Brake check light illuminated
3. ABS light *not* illuminated when running, but is on with the check before starting the engine (bulb ok).
4. Traction control not working based on wheelspin pulling away on test drive (recalled this after the test, didn't directly test abs - doh)

On the photos: Under the car, near the ****** oil pan, there are 3 connectors hanging down loose, all female from what I could see. Are these related - ie have they been disconnected from something to stop errors being shown on the dash?

Aside from this, faults are (not particularly worried about these):
5. Rear regulators not working (bad noises though...). A common issue I gather?
6. One rear door interior release not working (not the childlock, checked that)

I'm happy getting my hands dirty here, but I'm concerned having read negative info about the 06-07 abs sensors and the ease of replacing the fronts (if it is them) - are they a real pig to do?

Do you think I am on the right track with my diagnosis?

Cheers!

Ian

Those pics are rather small so it's hard to see the connectors.For the speedo/odo,ABS,brake light,and traction control issues is all to do with the ABS system as all of it runs off the 4 wheels speed sensors located at each wheel.Without knowing the codes set from the ABS system there is no real way to know besides a visual look which in most cases doesn't come up with much.If you can take it to a tech with a scanner that can pull the ABS codes it's pretty easy to fix after knowing what is wrong.

Thanks for the thoughts - on balance I think this one is a likely purchase, so I'll post the diagnosis up here for others if so. I'm off for a final check tomorrow.....

Cheers,
Ian

If you do pick it up, a common problem in the 2007's is the rear ABS wire from the wheel to the cabin on the right hand side gets internal breaks in it. It looks complete from the exterior, but doesn't work properly. I rebuilt that portion of the harness on my 2007 when I had ABS issues and it fixes the problem.

Did you just splice into the harness from the point it enters the body under the rear seats, or did you remove the seats etc. and go further in? Just getting an idea before I remove lots of stuff perhaps unnecessarily...
