06 Yaris T3 jumping gearbox

Recommended Posts

Hi all, sorry if this seems like a noob question...

My girlfriend bought a Yaris T3 on a 06 plate with the MMT gearbox. It bunny hops when starting at low speed. I've googled the problem and one fix seems to be resetting the ECU and MMT computers but the only info i've found points to links that no longer exist on how to manually reset the ECU and MMT computers, and other threads seem to be 10 years+ old.

Does anyone have this information available? it would be most appreciated.

I *did find this:


is it the same procedure for all MMT gearboxes?
