Hi everybody, Just curious if anybody could help, our Avensis d4d tspirit was fine when we went to work yesterday but when we came out of work 12 hours later we found the vsc, traction control and the malfunction indicator lamp were on. We have taken it to our mechanic who has said it is coming up with the error code c1201 but he's completely stumped as to what to do lol (really fills us with confidence!) We can't afford to go to the Toyota Dealership and wondered if anybody had any ideas what this is and how to fix it? Many thanks :help:

Hi, c1201 relates to a communication stop between ECU's , it is possible that your mechanic did not look at the right system and probably assumed that as the vsc lights etc were illuminated then that is the system that is faulty. It is most likely that the fault is within the engine system but with vehicles equipped with vsc all systems are linked so a fault with one will log a code in all others ( normally a communication stop code as you have)
I would advise getting the other systems checked out.
