So it turns out that my Ignition coil shorted out, causing the ECM to switch off, which caused my tranny code. Replaced the Ignition Coil and the car started right up.

Thanks to anyone that took the time to look at my post!

Yes the grey one on the cooling fan carrier is working properly.

main fuel system relay also isolated and ruled out as a suspect.

Quick update.... found a wiring diagram (not sure how applicable it is) and apparently the pin that the ECM is powered by is pin A30. With ignition on, there is no power on that pin. I just bypassed the fuel pump relay just to rule that out... still no start.

Hello! I have a 1995 Volvo 850 Wagon, and recently the engine stalled suddenly, and won't start up (cranks fine). I have no check engine light, but when I try the blink codes on connector A2, I get nothing! Not even the 1-1-1 code! The only code I see is from the transmission computer for "Open...

Thanks for your reply! The fan stopped blowing after I disconnected the battery and connected again.

UPDATE: So I did a bit more troubleshooting here. While the 245 code is the only one I get on the transmission (port A1), when I try and read the codes on the Engine computer (A2) I get no response. Not even a 111 blink... nothing! I checked for continuity along the torque limiter wires between the ...

Hello all! I am really in a bind and I'm hoping that someone here has a solution to my problem. I have a 95 850 wagon (2.4 auto) and earlier today, about a quarter mile from my house, the transmission light started blinking, followed by my car stalling, and the cooling fan on full blast. Tranny ligh...

Hello all. I just received the second ECC from the wrecker and this one seems to be working (fingers crossed). I'll drive around with it for a while before pushing it all the way in to the dash, but I'm feeling optimistic. Thankfully the eBay seller is willing to take back the defective one he sold ...

Yeah I wasn't sure what to expect by powering the ECCs separately. I guess I was hoping to see the lights flash logging fault codes for missing sensors.

I have another ECC and Blower Module inbound from a wrecker. I'll keep you all up to date on the results.

Thanks again!
