Victor 888 Not responsive

[afclsn]

When the code is not enabled, the indicator light flashes orange, and when the code is enabled the light flashes slowly red. We have tried different pwm cables, and the problem persisted. Also we swapped the pwm cable and the ports on the digital sidecar that the pwm cable is in with the cable and port of a working victor, and the victor that was working before continued working, while the victor that did not worked acted as before, flashing orange when the code was not engaged, and flashing a red when the code was engaged. We also rewired the motor controller and are sure it is wired correctly. What could cause this? Is it a dead victor or is there some other mysterious issue that we are not aware of?
