2. 2.Connect the KVL to the radio via the TDN9390A keyloader
cable. When the cable is connected to the radio, the radio should
enter the keyloading mode of operation, and the radio should
display "KEYLOADING" or "KEYLDG" and make a beep tone.
3. 3.If the radio displays "ERROR 09/10" or "E09/10" then go to the
ERROR 09/10 troubleshooting section.
4. 4.If the radio does not go into keyloading mode, detach and
reattach the keyloader cable.
5. 5.If there is still a problem, refer to the universal connector
illustration found in the schematic and circuit board section of
this manual, and short pins 8, 10, and 12 on the universal
connector together. If this causes the radio to go into keyloading
mode, then replace the keyloader cable.
6. 6.If the radio still does not go into keyloading mode, check the
continuity of the Front Cover/Display Flex and make sure that the
Flex is properly connected to the Universal Connector and to the
Controller Board.
7. 7.If the radio does go into keyloading mode, but after starting the
keyloading process the KVL display indicates "X FAIL", then check
to see if there are transitions on pins 13, 15, and 16 of connector
P1 on the Secure Module during a keyload.
8. 8.If there are no transitions on any one of these lines during a
keyload, check the integrity and continuity of the Expansion
Board Connector. If it is OK, try replacing the Controller Board.
9. 9.If there are transitions on these lines, try replacing the Secure
Module.
10.10.If the KVL display indicates "X PASS" but you cannot hear a
keyload verification tone, then check the volume of the radio. If
the volume is OK, troubleshoot the receive routing paths in the
radio.
A cable, Motorola kit number TDN9390A, connects the MTS 2000
radio universal connector to the keyloader.
This section gives instructions on retrofitting a secure module into a
