Hi there. These codes keep coming back then disappear for a little bit and then come back again.(battery is tricked charged every week) The ABS fault on the dash comes on usually every time I start it then on the way back it usually dissapears. All the sensors are working. Last night the handbrake kept releasing it self also. Some help would be greatly appreciated.U0415U0401

 

Yes. there are so many threads on this very issue.
You may keep the battery charged but the million dollar question is: what is its current capacity?
I think you will find that if you disconnect it for 12 hours following you “fully charged” state, it will not register well.
Invalid data, Abs issues and epb issues have one common root cause… there is a reason why in the workshop manual it clearly states “confirm battery is fully charged”, first.

 

Oh thanks I see, so a new battery might do the trick?

 

If you are going to get a new battery. Two things to keep in mind. 1. Look at an AGM battery, its more expensive but they have a longer life than the other type. 2. Whatever battery you buy should be fully charged before installation. Batteries lose power when they sit on the shelf.
