Hello,

I have been trying to troubleshoot this issue for over a week without success. I have repaired a few forklifts in the past but this is the first Toyota for me.

This lift is new to me. Since I received it, it's Throwing an error code C0 that comes on when the key is turned on.

I have gone through the troubleshooting guide in manual as best as I can follow but the manual very hard to follow and I think it leaves some information out.

I have tested the drive unit transistors and the contactor coils. One of the contacts (MG) is chewed up but it's not sticking on. I monitored the coil voltage for that contactor during startup and it was never energized.

At startup the only contactor pulls in and it's not in the drive unit its the MP contactor on the material handling panel.

I've inspected all of the cabling going to/from the drive unit.

The battery appears to be good and is fully charged.

I got what appeared to be incorrect reading when ohm ing the DAD and flywheel diodes and the RAD but I will check them again.

I do not have access to the SST to test the boards.

I performed the continuity check on 2-38 from the manual I got the following:
P2->N1 = 5.8K (Should be 10 to 25 ohm)
N1->P2 = 3.0K (Should be O.L)
P12->N1 = 0
N1 -> P12 = O.L.
I could not see the test conditions for this test anywhere so I had not disconnected anything prior to the continuity test.

Can someone please help me pull this together so that I can understand the next steps?

Thanks for your help.
