Unsafe Condition
When the outflow valve (OFV) manual mode connector is not connected, the manual mode motor and altitude limitation are not properly tested. This could result in a dormant loss of several CPC [cabin pressure control] backup/safety functions, including OFV manual control, altitude limitation, emergency depressurization, and smoke clearance.
