Symptom List:
ANTENNA FAILURE
COP FAILURE
EEPROM FAILURE
INTERNAL FAULT
RAM FAILURE
SERIAL LINK INTERNAL FAULT
STACK OVERFLOW FAILURE
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be ANTENNA FAILURE.
When Monitored and Set Condition:
ANTENNA FAILURE
When Monitored: Every 250 milliseconds with the ignition on.
Set Condition: The SKIM's microcontroller determines that an antenna circuit fault
occurred for 2.0 consecutive seconds.
COP FAILURE
When Monitored: With the ignition on.
Set Condition: The COP timer is not reset by the microcontroller every 65.5 milliseconds.
EEPROM FAILURE
When Monitored: With the ignition on.
Set Condition: When the value written to EEPROM memory does not equal the value
read back after the write operation.
INTERNAL FAULT
When Monitored: With the ignition on.
Set Condition: The SKIM has detected a fault during an internal self test.
RAM FAILURE
When Monitored: With the ignition on.
Set Condition: The RAM fails a test that checks the RAM's ability to retain memory.
SERIAL LINK INTERNAL FAULT
When Monitored: With the ignition on.
Set Condition: The SKIM fails an internal J1850 communication self test.
STACK OVERFLOW FAILURE
When Monitored: With the ignition on.
Set Condition: The microcontroller has exceeded its stack space limit.
