Clark ECX25:
Error code 243, can error 5

Does anyone have any experience with this? I have swapped the pump and master controller with a like truck, checked all the can connections and still have not found a for sure issue with the truck. Any information would be helpful. Thank you!

Check to ensure the two (2) Pin Jumper between the B1 and B2 Terminals on the Pump Controller is securely in place and is tight.
Check connections between the pump and traction control on PB9 to TB5 wire 83, PC1 to TC1, wire 73 and PC3 to TC3, wire 4.
