All Phase Lock Check
At this point, the All phase lock assembly appears to be faulty (its inputs
should have been verified already). Nevertheless, you may elect to use the
phase lock diagnostic routines or check the relevant signals at the assembly
itself for confirmation.
Note
If external source mode is the only operating mode with phase
lock problems, replace the A11 phase lock assembly.
