The car is getting a 112fault on the drive. The mcss gets a 2923 Ucm relay fault. Drive was replaced. Does relay check Bp never picks because z never picks to pick brake. Status on drive is no safe. Mcss has has all safe123, doors, comm lights ect. Thanks for any assistance.
It is p5-4 but on the DSS board in the drive I get 0 volts. I think this all has to do with my drive replacment. I have a OVFR02A-406, do i need to auto tune on the drive. if so how is this done. this drive reads no safe on the status screen. thanks I appreciate it.
I would replace the BH relay. It’s a mother [censored] to replace because it’s in the lower left hand corner of the controller with all the traveler wiring in the way. Sometimes you can see burn marks on the face of the relay and sometimes the burn marks are on the back side that connects to the thin rail. I have had what I thought was drive problems bad brake switches a bad BP relay and I kept chasing my tail until I replaced BH. I have 9 of these GCS-R controllers on maintenance. If you Routine the controller and drive connections and use some canned air and clean them up good they are really not problematic. I hope this helps and good luck!
