Yep Tapley for brakes. As far as I recall ABS is none functional bellow 5 mph/7 kph. I have doubts that the rolling road will generate that speed.Tapley meter

i dont understand how they test ABS other than checking bulb function
to test something, there must be a standardised baseline, but different cars have different ABS set up in different ways, eg. some renault ABS systems will get involved with the all but the lightest brake touch on a dry road, yet others, eg bmw you have to really stand on the brakes hard to get interference
plus, you need all 4 wheels moving at the same speed or you'll generate a fault

RTFM is your response.

From initial issue of a "fail" notice you have 2 months in which to rectify any problems and submit the vehicle for a free re-test at the same test centre...
Now that the 2 months have elapsed, I have to re-submit the vehicle for a new CT test. Obviously I shan't be returning to the same test centre!
I have been trying to locate a test centre that has a 4 wheel rolling road - so far without success... Rumours are that such a test centre does not exist!!
Are you suggesting that I put a contract out on the guy?
Is there not an equivalent to Trading Standards out there?

Perhaps you should print out the entire ABS section from RAVE and take it with you to the CT centre ?
As far as I understand, the ABS ECU receives wheel speed, and looks for differences outside a tolerance range. It doesn't know if the wheels are contra-rotating, but needs the dyno to turn them at different speeds.
Post 99 vehicles with 4-wheel TC must have the TC disabled before testing on 2-wheel dyno.

That would indicate to me that it is not possible to test ABS on the brake test rollers. The frog tester is a prick.
I would suggest that you need to raise a complaint with whoever the French equivalent of VOSA is & see what they say.
The other alternative would be a report from a franchised LR dealer that your ABS is performing correctly - then see if the loon tries to say it isn't. At which point a complaint as above.

Sounds like all P38's are inherently unsafe,
only one thing for it,......................burn them.

Standard wheels and rubber
There could maybe, possibly be a problem we are unaware of (as unaware as the tester guy
Over here you sometimes have to explain the abs light doesn’t go off with ignition but when moving but not normally an issue. My guy is a Landy guy so I never have the hassle he understands himself
Your ABS light does go out @ xx kph?
Only option I see is go somewhere else or ask him how much to fix and pay his extortion racquet
The guy was most indignant when I mentioned to him that the ABS light only goes out once you exceed 7kmph.. He said it's not that!
Thank you. This is interesting. I'm pretty sure that the test guy didn't disable the Traction Control...
As a matter of interest, where is your attachment taken from? This info is not in the Owner's Handbook that I have.

I know it's not helping the OP, but I have changed the test centre I use this year. I used to be quite happy driving 30 miles to get mine tested (200Tdi 90 - 2.4 VM RRC - Citroen based camping car) then the bloke left, and the replacement was a young guy who knew nothing but the book. Found out where the original guy is and now drive 10 miles more to get to him.
Difference is that he knows Land Rovers inside out, he is also quite considerate of a vehicles age when revving the engine for the emission test, (unlike the other ****)
Testing stations in France are just that, no remedial work will be done, I suppose that won't stop a tester recommending a mate to do the work for a few bungs.

Thanks for your comments. I can understand why you would want to go the extra distance to have the same guy test your car.

Take it somewhere else.
They can use a set of additional rollers to put under the rear wheels to give them the all wheel break test. Last time they didn't do mine because they were pushed for time. I also asked the tester to allow it to be switched off and settle for a couple of minutes before revving the beans out of it.
Change your CT station.

Owners manual p130.
Only states must be done with someone famiilar with LR testing procedures due to the AbS and constant 4wd.

It's in the ABS Brakes section of the RAVE workshop manual. Download RAVE.
Alternatively it's here in an online copy. https://workshop-manuals.com/landro.../anti-lock_brake_system_description/page_981/
Can I just check something? You're quoting from the Owner's Manual. Is that different to the "Owner's handbook" that comes with the vehicle? p130 in my "Owner's handbook" does not have this information.
