   They are not system under voltage they are Diagnostic Codes. There will be a troubleshooting procedure for each one. You will need a digital multimeter as a minimum. What is the machine Serial Number.?

   Here we go. Based on the fact that you have four Codes all the same -5 suffix leads me to believe you could have a common wiring harness problem (solenoid return sicrcuit maybe.?) somewhere, but following the troubleshooting procedure should get you to it. You would likely also beneift from having a complete electrical schematic. Check your message inbox.
