Fanuc Robot - DTERR Alarm (GRP 1 , AX 1)

Hi everyone , the electrician changed the connector for the encoder cable in Joint 2. So I got DTERR Alarm in all axis and I reset the RESET PULSE CODE ALARM , and reboot it. Now , its having same DTERR alarm only in Axis 1. The cables are fine now. am I missing any steps ?

I didn't jog the robot yet. Should I move only Joint 2 ?

because when I check the pulse , Joint 2 is having pulse but Joint 1 doesn't have it.

Even though only the joint 2 encoder cable connector was changed.
