Hi 22Tony,
Is this the first time you've had anything odd / random happen to it recently, even if it seemed to fix itself?

The starting point for a lot of things can be the battery so if it's old try giving it a good charge or connect a booster pack and see if that "cures" it temporarily.

When we're the brakes last serviced?

The connectors for the abs are inside the wheel wells and not well protected so can corrode and the cables themselves can wear through. Both easy enough to check - you might not even need to take the wheels off.

Everything works fine. Brakes rear and front 70 % like new. Ex owner say :the sensor cable pads is damage,for these reason i cannot acces with elm327 multiecuscan ABS system?

If you're confident it's not a battery problem I'd check the connectors for the abs as they're not very protected given where they are. Maybe cleaning them up might help but you might also see if something else that's obviously damaged or disconnected.
