Hi hazard
Check this thread for opening the front trunk. How to open hood when battery is good
I have the same problem with mine I had about 10 to 15 litres of water under the front seat from blocked drains. My board was like yours and had corrosion on it like yours. I cleaned it with alcohol and it still had the same problem but mine would start but key buttons would not work. So I removed the seat again removed the board and sent it out to a company here close to Ottawa and I received it yesterday. I will try to install it today if it can stop raining and will let you know if it works.

For reference, this eBay auction has a good picture of that module:

What I do know is that the interrogation to the transponder in your key passes through that module. That connection is required for the car to start.

a little corrosion on one of those connectors under the seat may still be the problem. I had to replace the entire connector on one of my cars, too much corrosion.

Best of luck, sir! That is a lot of water! We've been getting a LOT of rain lately here in ohio from the coastal storms in the gulf moving up north...


I was able to get access to the frunk two days ago. i now have the cable hanging out of the front so i can open it at will while still being able to close it.

My ignition switch is giving he "click" in a couple places when i turn it.. i think pin #4 on the unit might still be having issues.. I am goign to go over the plugs again more thoroughly in a few.

it seems like it's getting all the way to "just need the go-ahead" to start and that signal isn't getting there. I think pin 4 (immobilizer control) has something to do with it.. but just a hypothesis at this point.

If it is not solved today I am going to phone a friend for a durametric call. I don't want to use up his last VIN slot on his unit, so I'm trying to eliminate everything i can think of before doing that much.
