Hi

This car has been unused for six weeks and when I drove it yesterday , the handbrake was binding initially and the above warning-lights were showing. Since there was no problem when it was parked in April, I am thinking that these two lights are being driven by the same sensor, which has maybe got a bit of moisture in it or developed a poor connection somehow in the interim. I drove about 30 miles and the brake has re-set itself, but the lights are still there.

This is a friend's car and I don't have any books/documentation, so I'd be pleased to hear your thoughts before I start crawling underneath - and probably looking at the wrong wheel !

There is a sensor for the abs which detects if wheel has locked up during braking. They can fail but I'd initially unplug, clean up (ensure dry) then reconnect.
 
As you suspect, the greatest issue may be identifying which wheel.....
As said above, each wheel has a two wire sensor, check for fraying which is often the fault. The front wheels have a reluctor wheel on the outer end of each drive shaft which may have rusted off, the rears I think have the reluctor in the hub or even the bearing.....I give each area a good blast with compressed air to shift any debris.
If its nothing obvious, perhaps a scan by an able garage could be the next step - the ABS module is delicate on these and expensive, although they can be repaired.

Thanks John. If there is fraying, is there a short replacement harness that is available ?

Im pretty sure there is.....I do recall the front ones have a harness and connector, the latter was on the engine side of the inner wing but I dont remember how old the car was. The items came from a motor factors, rather than a dealer so the price was fair. I cant comment on the availability in France, of course!
