Hi 2007 avensis, manual, 2.0 d4d diesel with 185k miles I've had the trc off, vsc, abs light appear on the dash. I've plugged in a code reader but no fault appears. Initially the TRC and VSC lights came on but after restarting the engine, they would dissappear. Took it on the motorway on a 300 mile round trip and the 3 lights came on and now do not go off. Any ideas what it can be? Thanks in advance
