Had a flat tyre the other week, and put my spare wheel on which was a slightly different tyre size and drove it back home. The ABS light appeared at some point (which wasn't entirely suprising to me, as one back wheel was obviously turning more or less than the other - confusing the ABS).

Now fitted new proper size tyre, and the light has stayed on. The battery has also been disconnected for a while since, now connected up again but the ABS light is still on.

Is there a way to reset the ABS or could I have another problem??

Just checked, there's only 25mm difference in the circumference between 235 40 18 (normal) and the 225 40 18 (spare )I put on!!

Any ideas peeps??

 

Kev,

You must have another problem as the system resets itself if the fault dissapears after a power cycle change.

It is possible to read fault codes from these ABS units.

I have a code reader here if you get desperate
