every time I start the engine, the "ABS Failure Workshop" err msg pops up for a second, then disappear. Followed by the "PSM ON" msg. no warning light "!"

everything works fine.

 

But the "ABS Failure Workshop" err msg is very annoying.

 

any idea what's wrong?

This was a symptom of the battery going out on mine.

Quite often,the  occasional MIL for both ABS and PSM turn out to be voltage related (weak battery and/or alternator).  Get your battery load tested and have the alternator checked as well.

The battery is only 2 months old.

without the dynamo on, the voltmeter show only 12 volts. is it too low?

should it be 12.x volts?

Follow the advice suggested by JFP, 12V without load is indeed too little.

Way too low, should be around 14V.

You have 12V with engine off, which is OK.

 

When engine is running you should have around 14V

The battery voltage, unloaded and disconnected from the power circuit must be at least 12.4V, otherwise there is something wrong with load, the battery itself or power loss.

with the engine OFF, here are voltages :

the jumpstart ends : 12.22V

the 12V socket (cigarette lighter) : 12.06V

 

are these normal?

Seems a bit low, I would strongly recommend getting the battery load tested.
