Hi,
I have Lexus RX400H 2008 model (Toyota Harrier Hybrid), the issue is the vehicle stopping while driving, then it shows Check VSC system and Hybrid control system. I faced this many times. While driving vehicle suddenly disengage driving and can't control steering wheel. Since the vehicle still moving can be park with saftly. Then swich off ignition and then switch on all the errors are fixed.
So have done following things but issue is still the same.
*. Changed the normal battery.
* Changed the hybrid battery.
* Change the Hybrid battery control module.
* Change the temparature sensors.
* Swaped with same inveter.
Non of above method worked. I am in very curious situation what to do next. It seems issue is with power steering or hybrid system.
Can anyone give your valuble ideas on this issue.
