Tac 50 (2000) 152 fault

Hey guys working on a Tac50 currently on shutdown. Showing a 152 fault. Any experience with this one as its a B44 only. Thanks in advance.

It helps to have the right generation of manual for the controller. Turns out 152 is an excessive drive temp fault. Either dtok or fan input failure.

Ya that's a problem. They just re-assigned fault codes for new equipment. I keep the most current help files in IMS and the old one on my desktop. I would make sure the fans are working and replace the PMI module.
