09withmindofown Posted October 24, 2022 Report Share Posted October 24, 2022 Hey new to forum and new proud 09 Journey RT owner. At random when I try to start up I get a flashing red security light and no cranking. If I get out and push on the connection closest to passenger side of the ECM, it starts right up and runs fine. Also when it does this the remote start won't work. I'm thinking a pin is loose inside the ECM. As far as I've read to replace the ECM it has to be programmed at the dealership? Or are ecms from flagship1 really plug and play? It's so sporadic that I keep forgetting to fix it and all I have to do is open the hood and wiggle it and I'm good to go, but someday, likely, will be the last time that works. So any help on getting it replaced?? Quote Link to comment Share on other sites More sharing options...
2late4u Posted October 24, 2022 Report Share Posted October 24, 2022 might just want to remove the connector and see if there is any Corrosion on the pins or see what might be the problem,,if you called the company that you are talking about to see if it is truly plug and play?

John/Horace Posted October 24, 2022 Report Share Posted October 24, 2022 Yeah like 2late4u is saying. Gently un plug and look for corrosion and clean pins with isopropyl alcohol before reassembling. Im pretty sure ecm are normally plug and play if you have the correct one. Unit has to exactly match vehicle options. Used ones can be reprogrammed to clear stored vin, odometer milage etc if right scanner and Tec person is involved. Used one can be configured to fit different vehicles.

09withmindofown Posted October 24, 2022 Author Report Share Posted October 24, 2022 Previous owner put dielectric on connectors so that could be the problem. It may have gotten down into the connector so might be a little difficult to clean unless there's a spray I could use. I'll give it a go and post results Quote Link to comment Share on other sites More sharing options...

09withmindofown Posted October 30, 2022 Author Report Share Posted October 30, 2022 Okay so I got some electrical spray and cleaned the contacts thoroughly. It's losing connection less it seems. Still not dependable. I took the ECM apart and the solder on the pins is all good. I've got it narrowed down to pins 1-38, which is the connector towards the passenger side. I need to find a pin out wiring diagram so I don't have to troubleshoot every wire. I'm assuming it's either ground or + on that connection. Next step is to replace the connector? I'd prefer it to just be a pin or two if I had a diagram. ? Quote Link to comment Share on other sites More sharing options...
patsjourney Posted June 20 Report Share Posted June 20 I realize this post is almost two years old but I was just curious if you found the correct wires in the harness connector that supplied power and ground for the ecm. I have the same problem on a 2009 Journey 3.5l V6 fwd. Same connector same issue. Wiggle the connector and it starts. I tried to open the ecm but didn't because of the gooy insulation. I too wanted to check for cracked solder joints. Hope you fixed your problem. Quote Link to comment Share on other sites More sharing options...
