How to test for a shorted Transistor (fault code C0)

Toyota 5 Series with a code C0 right after key on.

I have been following you since 1 year now and your diagnostic procedures are a masterpiece. I had to troubleshoot and fix 2 Toyota 9BRU18 reachtrucks without any information on them. One of them with starting issues (Battery discharged, Code FG Fuse control board internal damage repair) and the other one with all cables cannibalized and cut (repaired and face also Code GD, steering motor sensor)

Nice work, I had this kind of issue with a TCM FB-15 2008 with steering problems. Steering motor is handle by 2 pair of IGBT modules in H configuration and once 1 of the transistors is shorted it disable the whole function

Not sure if you got my message, I try again. I have a Toyota 15, 1997 year. issue with Contactor not clicking, no contactor. We tried changing the main contactor and computer box but still sometimes the main contactor does not click. the truck is fully electric and the battery is new and good. Sometimes the contactor clicks and sometimes not even with a new restored computer case

Am young technician in the Caribbean fixing forklifts my self . But I need a good scan tool for them ; am working a several different brands so can u recommend me a forklift scan tool please sir .

[@forkliftgeek10]

There is no generic scan tool for forklifts. Each manufacturer has their own.
