VanTurismo

Hi folks i have a 2007/8 alphard. Ive replaced the aux battery and the main hybrid high voltage battery from a running vehicle. All the codes it had pointed to the HV battery. I checked them individually and more than 10 cells sat at 5v I replaced the cells all 7.4v and balanced . Granted not max charged but should still suffice to start the vehicle. I get the same noise As though it wasnts to start it says ready. You put it into drive and you get a humming sound and eventually it stops And then no noise Nothing happens and ready light Disappears. Anyone had a similar issue ? I hold the accelerator down it wont fire the engine up either Any answers would be greatly appreciated

Thanks for that bud. Mine wont even turn the engine on to charge the battery. Ive had several computers on it but none seem to be able to pull any live data. Im close to checking battery cells manually. Im actually a HV tech for ford but I'm stumped with this one with no real direction to follow . Will be sure to update if i figure it out though

Hi there sorry to drag up an old post. I have all of the above issues but the vehicle wont drive . Did you figure out the issue? I
