      I believe J220 is the ECU.

          Do what it says - check earth connection on ECU contacts mentioned, also it is possible, that chips iside ecu are somewhat badly programmed.

          Also check voltages, battery and stuff. When ECU is getting not enough power, sometimes it is spitting weird errors.

              Yes this is either an earth problem or bad checksum inside ECU.

              Small chance its an ECU fault.

                  modified chip installed, somebody hasn't bothered to modify/adjust the checksum as Paul indicates, very common.
