ayjayef Posted September 4, 2018 Report Share Posted September 4, 2018 I'm wiring up a Fury and all was going well (see: before.jpg) and next morning, without any changes and nothing touched I turned the ECU back on and it looked like this (see: after.jpg). Faults are: [10:33:03 AM] ECU Fault Code 74: Analog 5V Supply Error [10:33:01 AM] ECU Fault Code 73: Aux 9/10 Supply Error [10:32:59 AM] ECU Fault Code 47: An Temp 2 below Error Low value [10:32:57 AM] ECU Fault Code 44: An Temp 1 below Error Low value [10:32:54 AM] ECU Fault Code 35: An Volt 9 below Error Low value [10:32:54 AM] ECU Fault Code 32: An Volt 8 below Error Low value [10:32:52 AM] ECU Fault Code 11: An Volt 1 below Error Low value So it seems that Fault 74 is causing all the sensors to error which makes sense. It also seems that Fault 74 is because 5V is shorted to ground. I removed the sensors one by one (no difference) and checked the wiring (no problems found). Then I removed the Link A&B connectors from the ECU to see if there was anything connected to ground (Link A 25,34 and Link B 25,34 are the only pins earthed and they were meant to be) So I can't find any problems in the wiring and am starting to wonder if the ECU has a problem with the 5V. What is the minimum wiring needed to run the ECU to test the ECU 5V channel? Link A5 (14V+) Link A25,34 (Ground) ...and then test the 5V+ on Link A32?
