5.15 Keyload Failure
KEYLOAD FAILURE
Synopsis
This failure relates to only secure equipped radios
and indicates a failure to load key with the KVL
indicated by the message “KEYFAIL” and keyfail
tones.
Typical failures would be :
1) Open between the GCAI connector and the
microprocessor which prevents the keyloading.
2) Use of the wrong KVL or keyload cable.
3) Failure of the secure circuitry.
4) No secure personality in the radio codeplug.
With KVL attached to radio
and radio on, verify display
message “KEYLOADING”
Initate a keyload
and verify activity
on VoCon board
at J4001_65
Correct

Keyloading
Message”
displayed?
With KVL attached to the radio
and radio on, initiate a keyload
from the keyloader and look
for activity on keyload signal
at R2005 on expansion board.
Initate a keyload
and check for
activity at
J4001_38
Obtain correct KVL
and cable

Verify the radio has been programmed with the correct secure algorithm and
verify using the correct keyloader.
