Try to replace the front door interlock switch, and if this not solve the problem inspect the Registration module, 77-325 is a code from registration area (dirty sensor, jamed paper, open wires).
Hi there guys got some strange codes over the weeknd
77-325 and I think the one prior wa -77-222
the latter I think was due to something blocking a sensor so we got that out when went to change the blade on the IBT assembly
we got the 77-325 after reboot happened twice then stopped
just wondering what could be the cause
