3.5.5 Some commands from connector E not operating

All signals present at connector E are exchanged directly with motor control board
(222) through connector J1 of connector board (219) and connector J12 of motor control
board (222)
TESTING SIGNALS FROM OUTSIDE
□ Connector board (219), connector J2, signals are shown in table, with power source
powered and accessory connector inserted in E.
To improve access to the table measuring points, it is advisable to extract connector
