Toyota 7FDU30:
CODE AD-8

Hi, I have this unit 8FDU30 with mentioned code and think it is narrowed down to the ECU-B fuse but just keeps blowing, runs fine but no travel/hydraulics, any help would be greatly appreciated, thanks.

The ECU-B fuse supplies voltage to the SAS/OPS ECU and OPS buzzer located under the dash behind the hydralic linkage. The power supply at connector A21 pin 8. The ground for the OPS buzzer comes fron connector A21 pin 11. I would start looking at those locations and work your way back to the fuse.
