From personal experience the Actros was always the worst offender with faults on the dash display. On most occasion there was no defect. A favourite was hooking up to a trailer with LED lights and being told indicators or lights were not working, presumably because LED lights use less power and German technology is not that far advanced.

Iveco is a worse offender. Detects the same number of faults as an Actros, but with that annoying Iveco Buzz to alert you.
And, when it thinks it’s brake lights (ie LED brake lights), it does it EVERYTIME you touch the brakes 
Try a crapego, every time you go through a puddle it brings the amber abs on. Just avoid VOSA on rainy days!
EBS /ABS light on in a DAF ?
Pull in - stop - turn off any lights and remove key from ignition - count to 5 - 1 - 2 -3 - 4 - 5 put key into ignition and turn on - wait for the computer to run the checks - then start it up again . 99% of the time when you pull away the orange ABS/EBS light warning that takes over the dash will disappear.
Which goes back to my original question. What are you guilty of a defective component ie ABS,lights, or anything else or a defective computer system?
It is hardly a fair system whereby a manufacturer builds a product with inherent defects and the user carries the can for it.

Those rollover control things are complete bollox. The amount of times I’ve come to an unexpected stop on a roundabout because of those stupid things is ridiculous.
I had a few problems with an Actros stopping dead whilst taking tight corners at walking pace. This could explain why.

What I have quoted on is an incorrect coupling procedure - ie I did not turn off the engine and lights when coupling up . Thats not computer or component error 
I make a point of keeping the keys with me at all times whilst out of the cab, therefore the engine is switched off. The errors occur just the same.
Lukes right, Abs needs a pressure signal from the pedal to work the brakes. Ebs should technically work with only the red suzie and abs suzie connected, doesnt need the yellow suzie. The biggest bugbear of my life is ABS/EBS lights. The systems are so finnicky its unbelieveable. Theres so much to go wrong and tiny problems will cause the light to come on and they are hard to find. For instance on MAN and DAF trucks the ebs wiring runs through a conduit, which eats through the wiring on the inside of the conduit and causes a bad connection, or worse a broken wire and throws on the light. Ive only seen 1 trailer put on a red abs light and that was when i was driving and pulling one of a well known irish hauliers finest box vans. Took that trailer to puttgarden and back with my fingers and toes crossed!
Some of the physical faults with ABS are rusty discs or exciter rings, as the sensor cannot read the signals properly. Even worn wheel bearings can make the ABS light come on!
