Hi,
My daughter has a 2007 Toyota Yaris, with the MMT transmission fitted, and could do with a little help please.
Basically, I would like to know where the transmission ecu is located? The short story of what happened is below.
I got the 'gear' warning light on at first, plugged in and got p0810, clutch position control error. I removed the clutch actuator and opened it up, it uses a worm gear on the motor to move a toothed gear, which in turn moves the clutch arm. Well my toothed gear was partially stripped. So I ordered, fitted and programmed the new actuator. Just over a month later, the light came on again. Plugged it in, and it was exactly the same fault code. I thought, well it must be the clutch worn out? I replaced the clutch, although it looked very good, as well as being a genuine part. On road test, the warning light came on again! Well as my sister has an identical car, I swapped the clutch actuator from my faulty Yaris and put it on hers. I took her car out and it drove without any problem. I know know my clutch actuator and clutch must be good. My next step was to check the wiring, I would like to do a continuity test from the transmission ecu to the actuator wiring, trouble is, I don't know where the transmission ecu is! Does anyone here know, or have any other suggestions?
Thank you Steve
