Is it safe to remove the ECM, hook the battery back up and see if the car behaves any different?

Yeah the under engine splash pan is in place, never ran without it. No PS fluid leaking near the computers. I've done the best I can to check every connector/plug/ground I can find and haven't found any signs of corrosion anywhere else. Including all the connections on the CEM. The plastic box cover...

Also will these cars start with the MAF disconnected? I tested it both it with it unplugged and plugged in just to make sure it wasn't the MAF causing a no start and the car going into immob after an extended crank. Obv that wouldn't cause all the communication errors. But incase there is multiple p...

As of now, if I do the key fob lock/unlock 5 times. The immobilizer warning on the dash goes away and I can crank the car as soon as I put the key in. Sometimes the antiskid warning disappears at the same time, sometimes it doesn't. But they will both come back after a short period of trying to star...

Yes, we can clone this ECM. But, if serious, I do not think issue in ECM. For get more info, need to connect to car and read few parameters first. We can do it online. You think the ECM was still functioning right with all the corrosion on it? I don't have a VIDA DiCE. I could buy one if we really ...

To a used ECM?
That is very good to know, thanks.

A used ECM with the same Bosch part number can be cloned to suit the car. You'll need a Windows laptop and a Dice tool. I can fill you in and point you in the right direction with regard to who can do this for you when/if the time comes. Really? I thought the ECM had to be "Virgin". As in...

Could be mineral deposits (from the water) creating leakage currents. Wash the board with Electrical Contact Cleaner. You might be right, i was thinking it already went the step further and turned to corrosion. I will def try to electrical contract cleaner right now before taking extreme cleaning m...

Well I think we figured it out. The connectors on the ECM looked great, but I noticed it looked like water had been flowing down the side of the aluminum ECM cover in the past. So we popped the ECM open and it had corrosion everywhere on the back side of the PCB. Wonder if ultrasonic cleaning would ...

Yeah I just found a YouTube video explaining how the pink sliders work without the special tool. I'll pop the plastic shroud off ECM/TCM and see if I want to mess with the sliders lol
Thanks for the info.
