Operating Conditions

Enable Criteria ECU On
Failure Criteria EEPROM Write/Read Fail, CRC Error is detected Failure is detected if Error flag is set over 5times
  1. 2) ROM/RAM Error Occur
    • ECC detect function is used for ROM/RAM error detection

    Failure is detected if Error flag is set over 5times

  2. 3) MCU Trap Occur
    • MCU Trap module is used

    Failure is detected if Error flag is set over 5times

  3. 4) Stack Over Flow Occur
    • Failure is detected if the stack pointer is pointing out of the address defined available stack range
  4. 5) Cycle Time Over Occur
    • In case that the program execution time of Task 5 ms exceeds more than 10% of the loop time 10 times
    • In case that the program execution time of Task 1 ms exceeds more than 0% of the loop time 20 times
  5. 6) ADC Converter Error Occur
    • Failure is detected if ADC is not completed
  6. 7) Oscillator Error Occur
    • Failure is detected in case of oscillator failure while initializing the clock
  7. 8) PFM Error
    • PFM error occurs more than 5times
  8. 9) MPU Error
    • MPU error occurs more than 5times
  9. 10) MCU VCC 3.3 V detection
    • VCC Error occurs more than 30 times continuously
  10. 11) ASIC related error occurred
    • ASIC power, oscillator, nvm, spi and current error occurred more than 100 ms continuously
  11. 12) Core0/2 Stuck monitoring
    • Core0/2 stuck is occurred more than 4times
  12. 13) Rom Check Logic,
    • Check the consistency of flashed binary on IGN On.
    • Rom Check Logic is Application/Calibration Data Consistency Check. It can be seen that the detection is Application/calibration not programmed.
    • Failure is detected if Error flag is set over 2times
Failure/Mature Time See Test Failed criteria/Confirmation Failure criteria
Pass Criteria Ignition Re-On
Pass/De-mature Time Immediate.
Failure Aging 40 Ignition cycles.
