having a look around, you need to contact bba-reman as it look's like your ABS Control Module may have packed up, if so you can send it to them and they repair them,

Said that a few posts ago

I got that 1

Borrowed a code reader of a friend its obd2, and when I plug it in it displays connection error,  also as I plug it in the stereo turns on, (this is with ignition off)

[TheBoy]

Ign needs to be on.

You need a decent code reader, not the cheap tat, as you need to look in engine ecu, abs ecu and tcm for this one.

[m0rmh]

Sorry it was ignition off first, then to turn ign on after code reader had been connected, then it tried to talk to car which is when it came up with conection error.

the (cheap tat one's) granted cant go into depth in the car's brain but they can read and delete most faults  and if its more serious than it warrant's a main dealer anyway. a £20 reader does work and does what a £300 one does but without the price tag, u read it, fix it, delete it, job done. as it is im up £40 (vaux charge £60 reader cost £20) from 1st job.

So looking round the forum, more than likely abs ecu fail, thinking of second hand part as temp fix and send mine off for refurb, where do I find part number to get same unit,

Ive got one from a 3.2 auto here.Not sure if it will be suitable,but if you get the part number etc. we could compare and see if its the same. Are you planning on just swapping the ECU or the whole pump including ECU ?

Helpfully on bottom of ecu where you can't see it

hoping to just swap ecu, also sounds about right for my luck with where the part number is!. Going to look at the weekend,  as it is too dark and bloody wet of a night to do after work will let you know

I wouldn't be too hasty. As said, you need to get diagnostic information from all 3 ECUs to get the full picture. The classic ABS ECU failure causes both TC and ABS lights to come on, and total failure of the ECU including speedometer output. You are not seeing these symptoms therefore your ABS ecu is most probably fine.

In my experience, if ONLY a TC fault is reported by the lights, then it's a problem with communication between the gearbox, engine and ABS ECU since all 3 have to communicate for traction control to work. ABS functionality is stand-alone, so if this isn't indicating a fault, the ABS ECU itself is seeing no fault.

Good thinking. Get it to a tech2 with someone who knows how to use it,before throwing parts at it.
Kendal is a bit awkward. Its either down to Nottingham to see Fuse 18,or up to Fife o see Hotel 21.

my symptoms- TC light on constant, car with spanner light constant,  speedo works fine,
gearbox in drive feels like it is in winter /snow mode,  but using first gear picks up no problem.  Also no sport mode and no winter/snow mode, feels like gearbox running in a safe mode. Engine runs fine, TC button on dash does nothing . Think that is everything,  when we did pedal test got codes-- 2100 2106 2108   and 0500 twice,  does paper clip test do same thing as pedal test?

Have you tried a new switch before you get too involved

no haven't, but was wondering how the switch comes off, thinking of having a look at it over the weekend, along with other jobs to do, it is on the check list ,

[05omegav6]

Carefully pops out

This might help...

Shows you what to expect, but TC does simply pull out
