Hello all,
Thank you all for following up on this thread, much appreciated!
I managed to get a rebuilt ECU in Japan through the guys at Rama DBK Ltd.
Excellent service & speedy.
I think they must have put the rebuilt/reconditioned boards into a brand new shiny box, it looks brand new!
I plugged it into the car and after standing still for nearly 4 months, it started on the first go.
Gear changes were how they should be, all lights working properly and even the blinking "O/D OFF" light has sorted itself out!
I still have an outstanding order for another ECU and although the Toyota part number is the same, the Denso part number is (slightly) different.
The original ECU: 175800-1297
The other ECU: 175800-1296
Do you guys know whether this could be a problem?
I have tried contacting Denso but have had not reply from them.
Many thanks!
