5-4 Troubleshooting Procedures: Operational Error Codes
5.6 Operational Error Codes
During radio operation, the radio performs dynamic tests to determine if the radio is working properly.
Problems detected during these tests are presented as error codes on the radio’s display. The
presence of an error code should prompt a user that a problem exists and that a service technician
should be contacted. Use
Table 5-3 to aid in understanding particular operational error codes.
5.6.1 Power-Up, Self-Check Diagnostics, and Repair (Not for Field Use)
The following are additional action items to be utilized for the diagnosis and resolution of the
aforementioned error codes:
Table 5-3. Operational Error Code Displays
Error Code Description Corrective Action
FAIL 001 Synthesizer Out-of-Lock a. Reprogram external codeplug
b. Send radio to depot
FAIL 002 Selected Mode/Zone Codeplug Checksum Error Reprogram external codeplug

01/02 This non-fatal error will likely recover if the radio's power is cycled. In the event
that this does not resolve the issue, the radio should be re-flashed. As a last
resort, the FLASH ROM (U803) should be replaced.
01/12 The radio should be sent to the depot for re-flashing of the security codeplug.
01/20 Cycling the radio power should resolve this issue.
01/22 The radio should be sent to the depot for re-flashing of the tuning codeplug,
followed by re-tuning of the radio.
01/81 The radio should be sent to the depot for re-flashing of the host code.
01/82 The radio should be sent to the depot for re-flashing of the radio codeplug.
01/88 Re-flashing of the radio should be performed first. If this fails to resolve the issue,
then replacement of the SRAM (U804) is necessary.
01/90 Cycle power to the radio. Continued failure indicates a likely IC failure (MAKO,
PCIC, ABACUS). In this event, the radio should be sent to the depot for isolation
and repair of the problem IC.
01/92 The radio should be sent to the depot for reprogramming of the security codeplug.
01/93 The radio should be sent to the depot for re-flashing of the host code.
01/98 Send the radio to the depot for replacement of the SRAM (U804).
01/A2 The radio should be sent to the depot for re-flashing of the tuning codeplug
followed by re-tuning of the radio.
02/81 The radio should be sent to the depot for examination and/or replacement of
either the FLASH (U804), or the Patriot MCU/DSP (U800).
