Hi everyone, I've got a problem with a power control unit for tracking a liftcar. There is a problem of 2 parallel TSM 002(power transistors, I do not know parameters Uds,Ids,P ) for a motor - after running forward or back (not loaded) ,everything is ok, speed is ok, after pushing another liftcar(simulating loaded car) for some time ,transistors are broken.
(crossing Drain-Gate is destroyed, but no short circuit, no short circuit between D-S as well).A driver for TSM002 is a small board (the same like a driver for hydraulic motor with 2 TSM as well. (only combination is different TSM002+TSM001). Could anyone tell me what problem it could be? Thank you guys.

Hi Viking, how could I check the current?Is there any possibility in a display menu to go into it?So far,I have not spent any time to have a look what I can do with the display and its values.Have a look at "Toyota FBE15 Error Code" in this forum, there is more about CO error code and my case as well. You might help me more.thanks. As to the sensor- there are 2 same sensors in this control unit- 1 for drive,1 for pump motor, I have compared them-did not see any different , however, I did swap them, I will see what is going to happen.The car is 50km away from my workshop, so I have to go there.
check if the current sensor is working ,normal driving will read between 60-80 A
