If you have a known bad A or R pack BCU (aka top cover) I've been able to successfully repair 2 out of 3 I've had cross my test bench. As far as I know, I'm the only person actually repairing as opposed to replacing these units. I've also had success repairing failed ACMs, Inverter boards, DCCPs, displays, and BRDs. If you have any questions just text me at 602 752 0083 or email at maxvonauto@aol.com. Note, Oded's bad BCU is working again but with very poor high voltage isolation. Not very safe in this condition.
