FLSpecB Posted February 24, 2019 Share Posted February 24, 2019 Hello Subaru family. I am new to this forum and looking for some technical expertise. I have a 2007 Subaru Legacy Spec. B that has been a great car. Recently, the ignition coil connector for number 3 cylinder denigrated and may have shorted out. I installed a new plug and tried to start the car. The cooling fans both run wide open and I get a "Run Mode System Check" notification on the gauge cluster screen. I replaced the negative and positive battery terminals and searched for any lose ground but everything look correct. I tried to pull codes using my AP and a pocket scanner but neither would connect to the ECU. Does this sound like a bad ECU? What do you think?

Ironworker613 Posted February 27, 2019 Share Posted February 27, 2019 Sounds like the ignition drivers in the ecm took a dump. Make sure all ecm fuses are good and if so, you need an ECM. Link to comment Share on other sites More sharing options...
SesnaBlue Posted March 1, 2019 Share Posted March 1, 2019 Did you replace the coil pack? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
FLSpecB Posted March 2, 2019 Author Share Posted March 2, 2019 Thank you all for your replies. All of the coil packs are less than a year old. I checked all the fuses and nothing looks blown. Are there any fuses not in the two fuse panels that I should check? Link to comment Share on other sites More sharing options...
FLSpecB Posted March 2, 2019 Author Share Posted March 2, 2019 Does anyone know how to test the ECU to see if it is toast? Link to comment Share on other sites More sharing options...
