08 Toyota Tundra No Ecm Communiation No Start

So I decided to check it with a scanner and found I couldnt communicate with the ECM.

08 toyota tundra no ecm communiation no start. I tried using a re-manufactured ECU that was programmed with my VIN I also tried using a junkyard ECU when the re-manufactured unit wouldnt communicate. In this video I guide you. And its been raining a ton here this winter.

I need some help. Wife was driving the truck one day and got stranded. Also no communication to the computers was present.

Now like many Tundras it leaks onto the passenger floor mats when it rains a lot. Try lightly slapping the ECM with your palm and verify that all the wires are plugged in securely into the ECM. Any suggestions before I by a new ECM.

This truck died while driving no start spins ok no ses at all when I check with the techstream ecu will not respond. No instrument lights come on when key is turned on Could be a problem with the key switch or a main fuse. If you run across a 2008 Toyota Tundra 3UR-FE and have a no start no ECM communication condition and there is no Check Engine Light bulb illuminated during the function check disconnect the secondary air valvesThese have a tendency to short the 5 volt reference line and stop all ECM communication.

All lights was still on and ac power steering lost and hard brakes accelerater pedal went to the floor. Just a ton of stuff. Posted to Asian Driveability on 1162012 6 Replies.
