Hello Folks,, sory abouth my English when wrigting without spelling..

And the first 2-3 years did a lot of jobs on it... And thanks to these forum, i managed to get the car very good. But without forum, it had been to challanging.
After then several years with minnor trouble, I'm back with a ABS strugge.

The bad thing about these my post.. I can not give exsactely report from the beginnig sins my wife did drive the car for a period.. And it happend at same time as inn tank pump failure... and ABS lamp was seen as minnor...
Good to have someone to blaim for bad tek report


Well ABS checks done is.
If start up the car after a long rest ABS lamp on constant. When start to drive lamps turn of... for as most of time come on again after a few hundred meter/speed. Some time for more and sometime less...
If the lamp come on and do not go of when start to drive... it stays on.

Test done...

Speed works fine
Cruse works fine
All 4 blue sensor connectors opened and cleaned
el connector at ABS pump opend and clean
( all was found clean and good condition)

Check the plug connections on the ABS modulator are clean and in good condition.

You could always get a copy of the free diagnostic programme TOAF and see what that picks up. Covers everything and easy to use.

Currently working on an ABS issue with one of my rear wheels but now I've got the new backplates to do the job properly once and for all. (Fingers crossed / håll tummarna).

Good luck

Did you get the same number of pulses / volts changes on each wheel for a full revolution ? If one is significantly different then that indicates a problem .
It was 48 pulses per turn when I did my check

Hi,,, Thanks...no did not check that... it could very well be that it was not.


I had to do somthing, so open both rear bearings .. Did find som rust ,, it could be the error. I have ordered new bearings... So will try these..
And thanks for the 48 pulses tip.. I will check that when parts arrive,, and installed...

Yes a programme to run on a PC, I use an old XP laptop just for car diagnostics, and have helped others with problems and special options like one click open, enabling digital speedo etc. As the official T4 machines hardly exist in Scandinavia (and no-one knows how to use them) many owners in Sweden use this software, donate if you feel it's worth it.

Here's the home page: http://toaf.roverki.eu/index.php/en/ - you'll also need a special cable, lots of information on the MG Rover forum in the stickies.

Good luck

Connect meter, then very slowly rotate the wheel and tyre to check for the 48x switching points. A brick or similar on the ground as a position maker, mark the tyre with chalk or crayon, exactly at the switch points. Make sure the switching occurs 48 times for each revolution and through several revolutions. Just one missing, or irregular pulse is enough to cause the ABS issues.

Thanks all,,,, will travel for a few days...



And also because new rear bearings are on the way by post..
Handy when living contryside Norway, to order parts by internett, mostly from UK..



The 75 will rest alone inn garage...


I will come back
