Hi, The A6 fault is material handling switch abnormality, this means either you have a dodgy microswitch on one of your levers or it is incorrectly set up, so the logic thinks you are pulling back on a lever on start up, check also the cams on the levers as these collect dirt and grease and can turn microswitch on at rest. Very worst scenario is you have trapped loom to levers, hope this helps! Have worked on Toyotas for 10 years and now work on mitsi's. Good luck!
