To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.
Check to ensure the pressure transducer is properly installed and all wires are properly connected.
Check if the error follows the transducer. Disconnect transducer cables from the module (connectors 2 and 3). Reverse A and B connections and checkif the errors follows. If the error follows the transducer, replace the pressure transducer.
If both P6AX and P6BX error codes are triggered simultaneously, try disconnecting one pressure transducer at a time from the module. If disconnecting one transducer clears both error codes and allows the opposite transducer to begin reading pressure, replace the disconnected pressure transducer.
