Toyota Passo (kgc30) Transmission "D" blinks.

[Hasbee]

Car drowned in the recent floods. Water level was up to the tires, but it had reached inside the boot space. Towed the  car to garage, and was told that the ecu is out. Searched for nearly 3 weeks and finally found one. Had to reprogramme the immobilizer and the smart key, then the car started. After smetime had to replace the starter motor also. Now that its in running condition, however the "D"  mode light is blinking. Can anyone say what would be the problem? Where to fix? Should the TCU (transmission control unit) be replaced?

Welcome to the forum and sorry to hear that you were affected by the floods.

When you said that the water level was up to the tyres, what exactly do you mean? Half of the wheels submerged?

It's really difficult to say what's really wrong with a flood damaged car. Given that your ECU was fried, it might be an electrical fault or an issue with the transmission itself. Have you tried getting the ATF inspected to see if water has somehow reached inside the unit?

Also, I advise cleaning all the connectors that lead up to the transmission (actually, all of them that were unedr water) with contact cleaner before even attempting to start the car.

Yeh I too think that it could be some electrical fault cuz of mud..
