I'm working on a ECX30 Clark getting code 246..Slave ER I have replaced both controllers, checked jumper on plug B5 B11 on pump controller found good, Suspected body harness and replaced code still showing. Lift has no traction and no Hydraulics. Code suggests pumps safety is bypassed and only terminals it suggests are B5 &B11 on pump controller has anyone had this problem and has anyone any other direction you can suggests trying I have exhausted all avenues any other direction would be gratefully appreciated. Also the Manuel doesn't mention Slave ER in the code reference what does Slave ER refer too?
