Hi to all.
All begun with the truck shutting down 1 or 2 seconds after key on. Costumer calls and found the positive battery connection loose ( easy fix i thought)!
Repaired the connection and then codes AD-5,AD-6 and sometimes CB-2 were showing up. No hidraulics, no steering, traction OK. Checked fuses,all OK, measured wires between connectors CN111,CN103,junction CN231/CN234, all seems OK. Disconnected all 4 connectors in Main Controller just to clean the dust but after that when i plug the battery ON,it shows the code F1-1 and F1-2 immediately!
Now,could the bad connection of the battery blowed the main controller although the 10A fuse being Ok?
Grateful for any opinion,thanks.
