Otis mrl gen 2

Hi guys. I have a gen 2 that will not respond to hall or car calls. No lights when pressed
My safe 2 is lit
Safe is lit
Gds is lit
Safe 1 is lit
Etsc is lit
SC is lit
Car runs on inspection
After power on reset doors open and close
Ocss monitor says A-04 NAV
Mcss monitor status says NOR MGS INA IDL
No shut downs reported
Dbss status says mcss no saf
After reset my mcss faults are 2414 lwss tout loss
2703 drive fault
2819 RBI fault.
Ocss event log says 1201 mcss msg timeout
1202 msg sio
Dbss log says 900 mcss timeout and 913 mcss warning.
What do you guys think ?

2819 is your culprit. Your PULSE unit is in alarm.

Txs newmech 2819 says not used on gen 2 in my write up . Do you have any info or tips on trouble shooting 2819? Where and what is the pulse unit ?

Is that the belt monitor ?

Can I turn off the flat cable sensor with the service tool to get the car to run ? If so which menu is that under
