Technical What happens if you remove ABS fuse ??

[ukjoe]

Yes, indeed it did need that combination.. (But it put up quite a fight)

I have not used KKL for ages, and not sure I've Ever used the Green Adaptor

BUT.. Did eventually get it to converse

HOMEPAGE suggestS KKL and ELM for most relevant applications..

But wouldn't connect.. Or throw errors

AND without it connecting for a Scan with the ELM.. I Couldn't ascertain what ABS unit to set-up for

Annoyingly I don't have an image of the error code

@ukjoe should have..

But the code pointed to RH Front wheel sensor


So an excellent starting point

The Error would clear in MES, but the Dashboard kept pinging the fault message

Owner stated this dash error message error is intermittent..

Look forward to updates

Thanks again to @varesecrazy for all the time he spent trying the various cables etc to get the error code. So got it and now will have to get around to checking the electrical connection and then the sensor itself. Thanks also to everyone else's contributions and particularly @jackwhoo and @portland_bill

Front right speed not feasible..... that is really interesting

Same size wheels and tyres all round?

If tyres all same size I would be checking sensor and magnetic ring for dirt/rust contamination

Yes, same size tyres, wheels (and also all steel). I will check for contamination and connection. Thanks,

Apparently that side has "had work",

New bearing.. Not sure it it's a Rotor or a Pick-up in the bearing on those..

(Pretty sure my 99 T reg Marea JTD Was Rotors.. As a garage damaged it doing a bearing)

 

[jackwhoo]

I'm pretty sure it is magnetic ring part of bearing

 

[jackwhoo]

Just checked- it is a magnetic part of wheel bearing that induces a signal in the abs sensor.

Yes had new bearing in April 2022 which failed and was replaced, under warranty, in March 2023. Not sure when ABS problem started but must go back to middle of last year or so.

So, @jackwhoo do you mean that this bearing might not have had the necessary magnetic part? Or just that it failed? Or...? Thanks,

If it didn't have the magnetic part you would have had the abs fault light straight away.

Start by checking the sensor wires very carefully and what you can see of the sensor. Two wheel bearing changes on that side could have put stress on the wire /connectors and sensor.

 

[portland_bill]

If fault coincided with bearing change, bearing could be in backwards, i.e. outer face inwards. Reluctor ring therefore away from sensor.

Yes, but fault appears intermittent

So you would assume the bearing would be a constant..

Interested in what is discovered
