I have a 2003 KJ Verada with a similar problem to ben205vs posted 14-06-2013.This car was driven at suburban speeds (up to 70kph) for 4 days without a problem, but when driven on to a motorway and accelerated to 90kph it started and continued with a massive loss of power which continued until the car was driven the next day. TCL warning light was flashing. Ultrascan scanner dislayed "no communication" in traction control mode selection. Fuel filter replaced but problem still eexists
