Common problem it seems and I'm going cross eyed reading the millions of posts here (newbie syndrome) My 4ws light comes on after travelling approx a distance of 3km. It doesnt go off itself, but I can reset it by turning the car off. Unfortunately I cant keep turning it off every 3km! I've been reading about codes 21, 22, 23... How do you find these codes? And am I right in reading the 4ws motors are situated in the LHS rear wing? Any advice would be greatly appreciated, and any copies perhaps of diagrams relating to this bloody annoying issue!

Have a look in the files section for diagrams and the instructions for getting the error codes. The 4ws ecu is in the left hand quarter panel, the motors are under the car, the relays are under the bonnet on the left wing.
