Home Forums General Discussion Technical Questions 409 Fault Magnetek DSD 412

Working on a T4 getting 409s on my drive. For some reason my book is missing the page with the 409 on it.

My controller is throwing a string of faults starting with a 53, 102, 613. So I end up with a 409 on the drive just curious what that is?

409 = Positive Current Limit
-Verify/Adjust for P001 - set default at 250%
-Verify/Adjust for P003 - motor amps on data tag
It's not in my T4 book either but it was in the TAC50 book.

Sbrmilitia,

I'm showing in my Magnetek manual 409 is a unexpected CPU reset. I would look at the boards and connectors first. I believe the error codes you are getting suggest you lost the communication from the CPU board.

Dpram mailbox faults. Faulty communication between DSP and Car CPU thanks for the info on the 409

I'm glad it was useful...
