Hi all.. on holibobs in French France with very limited wifi and very basic tools !!

Started up three days ago and ABS and TC lights stayed on. Been on permanently for 150 odd miles now but speedo works fine all the time. Fluid level is fine. Fuse 19 is good.

Brakes feel fine under normal use, not tried anything daft. Fuse 19 is listed in the handbook as ABS/TC, is there anything else I can check easily ??

Any advice readily accepted !! 

[Gaffers]

just a visual check on Fuse 19 of by other means?  Sometimes they can look ok but a multimeter shows a different story.

Try whacking in a new one just in case.

If the speedo works OK, then the ECU has power and is working OK, so that rules out simple things like the fuse, although you might want to check fusible link FV1, as that supplies the high current side of the ABS ECU. I've no idea if the ECU dies completely if that has failed or just throws a code and disables ABS. I'd guess at the former, so that's a long shot.

If it's driving Ok otherwise, then I'd say it's probably not a serious issue. Probably a failed wheel sensor or similar. Can probably wait until you get home although a visual check of each wheel sensor might throw something up.

A waggle of the 3 big round connectors behind the battery might be worth a try, as most of the signals pass through these and it's not unheard-of that they come adrift.

Worth noting what engine RPM correspond to various speed limits in top gear, in case the speedo fails later.

Correction; I expect your car is an auto, in which case  it gets speedo info from the gearbox sensor.

The speedo uses the ABS

Cracked ABS ring?

Cracked ABS ring?

Given how much wine he throws in to his pikey van when he sejours in frogland, I wouldn't be suprised

I had this happen on a previous car that I just bought.
Solved the issues by putting the same size tyres on the front as we're on the back. Previous owner put smaller profile size on. :- /55 where the /65 should be.

Mercs are good for that trick too, but iirc Nige has always had standard 17"s on...

A voltage glitch perhaps That twenty five foot wine cooler probably consumes some juice, and if the weather in French France is half as shit as ours, then the car will be needing electrickery for lights and wipers etc...

It is in this part of French France!    Probably why it's called Brittany!

Many thanks for all the ideas ..  fusible links checked, new fuse tried,plugs by battery reseated - bloody horrible task - tyres checked.. still all the same size !! tyre pressures all within 1 psi /axle, 5 psi front/rear. unable to check each wheel sensor area due to ground conditions/laziness!!. Pikey coolbox is parked up and will remain so for a few days more !! Car did 150 miles yesterday  (Puy du Fou is FANTASTIC!!!!!!) with the lights on all the tims but no other problems. Probably a visit to Jamie to get the sensors read when we get home. many thanks ... let the drinking and eating continue ..

I'd suggest a genuine, non ECU fault.

Just use it as normal but remember you have no ABS, so don't drive like a twonk.

I had similar a fair few years ago and it was a bad connection on one of the rear cluster earth points, pressing the brakes was causing it to fail and put both lights on. Cleaned the connector and ask had been well for the last 8 years.

[Entwood]

Well it was dry enough today to actually get under the car, visual check of all sensors, wiring and connectors reveals nothing that looks wrong Now awaiting delivery of a "my Naff Code reader" to hopefully tell me whats up. If memory serves changing the sensors is a complete pain in the arse job.
