TEST 03 FAILED
Error Code System Message
TEST 03 FAILED - Auxiliary/external RAM test failed
Question
What does TEST 03 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer
TEST 03 FAILED: Auxiliary/external RAM test failed.
Possible Causes
External RAM test patterns could not be written/read correctly. Preserve data form bottom of RAM to top of Data Base. Does not preserve data abovetop of Data Base. Error Code 83 Hex is recorded in the Error Log for a failure.
Troubleshooting Steps
Check RAM devices and associated circuitry. Check RMA and it's associated circuity. Make sure RAMis in the correct socket. Check the microprocessor. Check the option switch. S96 on CPU 46-232828 or S75 on CPU 46-264974, to see that RAM is selected. Option switch 1 must be in the On (closed) position. Closed = 2k of RAM. Open = 4k of RAM. Change RAM chip first on CPU board U54 abd U107. If it still not work, the LVLE Power Supply is bad and need to be replace.

Error Number
TEST 04 FAILED
Error Code System Message
TEST 04 FAILED - Calibration data checksum failed
Question
What does TEST 04 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer
TEST 04 FAILED: Calibration data checksum failed.
Possible Causes
One or more calibration-data records do not match their stored checksum. Calculates the Check Sum for the Calibration Data Base and compares it with the stored value. Test fails if they are not equal. Entering Calibration will give a more specific error code for the check sum failure. Error code 84 Hex is recorded in the Error Code for a failure.
Troubleshooting Steps
Check Calibration and RAM. Identify the affected calibration, correct it, and rerun checksum/calibration.

TEST 05 FAILED
Error Code System Message
TEST 05 FAILED - Watchdog timer test failed
Question
What does TEST 05 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer
TEST 05 FAILED: Watchdog timer test failed.
Possible Causes
Write to timer and read back several times. Test fails if timer is high for more than 75 milliseconds or less than 25 milliseconds. Error Code 85 Hex is recorded in the Error Log for a failure. Error Watchdog timing/reset response is outside expected limits.
Troubleshooting Steps
Check HC123 on shot and associated circuitry. Check watchdog timer circuitry and CPU timing components.

Error Number
TEST 06 FAILED
Error Code System Message
TEST 06 FAILED - Programmable interval timer test failed
Question
What does TEST 06 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer
TEST 06 FAILED: Programmable interval timer test failed.
Possible Causes
Timer 1 cannot be checked because the program does not have direct control of it's input gate. Initialize timer 0 for 16 kHz and timer 2 for 120 kHz, Count pulses to verify frequency. Check output 2 for 50% duty cycle. Error Code 85 Hex is recorded in the Error Log for a failure. Timer could not generate the required interval/count behavior.
Troubleshooting Steps
Check 82C54 timer, HC151 8 to 1 MUX, oscillator, and all associated circuitry. Check interval-timer IC/clock and associated CPU circuitry.

Error Number
TEST 07 FAILED
Error Code System Message
TEST 07 FAILED - Analog-to-digital converter test failed
Question
What does TEST 07 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer
TEST 07 FAILED: Analog-to-digital converter test failed.
Possible Causes
Read +5 volt power supply. Test fails if result is below +4.5 volts or above +5.5 volts. Error Code 87 Hex is recorded in the Error Log for a failure. Also test +24V and +/- 15 supplies if option switch is set to do so. (+24V and +/- 15V supply test only with firmware 46-302688G1 / 46-302687G1 and later on CPU 46-264974. Test enabled by dip switch #3.) A/D converter reference/power-supply input is outside expected range.
Troubleshooting Steps
Check +5 volt supply. AD574A A/D Converter LF398 sample abd hold, AD5706 16 to 1 MUX, HC374 latch, and all associated circuitry. Check +5 V/reference supply, A/D converter and CPU board circuitry. If display showed "DRIVE WORD LIMIT" then RAM chips is bad, maybe bad U342 and U413.
