Troubleshooting Procedures: Power-Up Self-Check Errors 5-3
5.5 Power-Up Self-Check Errors
Each time the radio is turned on, the microcontroller unit (MCU) and the digital signal processor
(DSP) perform some internal diagnostics. These diagnostics consist of checking the programmable
devices such as the FLASH ROMs, internal and external EEPROMs, and SRAM devices. At the end
of the power-up self-check routines, if an error exists, the appropriate error codes may be read using
the Customer Programming Software (CPS) from the RS232/USB bus on the universal (side)
connector.
NOTE: If you have an earlier version of the radio, it may display either 09/10 or
09/90. This is the result of a programming error, and can be cleared by
turning the radio off and on. If the problem persists, send the radio to the
depot. Newer radios will not display this error code.
In the case of multiple errors, the codes are logically ORed and the results displayed.
Table 5-2. Power-up Self-Check Error Codes
Error Code Description Corrective Action
01/02 FLASH ROM codeplug Checksum Non-Fatal Error 1) Turn radio off, then on.
2) Reprogram the radio
codeplug.
01/12 Security Partition Checksum Non-Fatal Error Send radio to depot
01/20 ABACUS Tune Failure Non-Fatal Error Turn radio off, then on
01/22 Tuning Codeplug Checksum Non-Fatal Error Send radio to depot
01/81 Host ROM Checksum Fatal Error Send radio to depot
01/82 FLASH ROM codeplug Checksum Fatal Error Reprogram the codeplug,
then retune the radio.
01/88 External RAM Fatal Error (Note: Not a checksum
error.)
Send radio to depot
01/90 General Hardware Failure Fatal Error Turn radio off, then on
01/92 Security Partition Checksum Fatal Error Send radio to depot
01/93 FLASHport Authentication Code Failure Send radio to depot
01/98 Internal RAM Fail Fatal Error Send radio to depot
01/A2 Tuning Codeplug Checksum Fatal Error Send radio to depot
02/81 DSP ROM Checksum Fatal Error Send radio to depot
02/88 DSP RAM Fatal Error (Note: Not a checksum error.) Turn radio off, then on
02/90 General DSP Hardware Failure (DSP startup
message not received correctly)
Turn radio off, then on.
