Hi, I have tried to check the fault codes but all I'm getting is a continual flashing of the engine check light, the motor is A transplant or a reconditioned one, it starts, runs , and depending on load, the engine light comes on and off ,but does not seem to affect the engines operation, I believe the ECU's are no longer available, and also that the capacitors might need replacing, I can do that if needed,be nice to know without going to a toyota dealer though. Thanks, Bob.
