IS200 3s-fe engine ECT Power Blinking
 

Ive diagnois the problem it says soleniod A Electrical Malfunction. which means i cant use the electronic mannual shifts on the steering wheel and it doesnt shows M or What gear number 1 2 3 or 4.

but the auto transmisson works fine.

ive replace both solenoids A and B and serviced the auto transmisson yet the ect power blinks on the dashboard.

tried erased it yet it comes out blinking.

what could it be? any advice? would it be the Electronic Control Unit Faulty? im in needed help now...
