Symptom List:
ANTENNA FAILURE
COP FAILURE
EEPROM FAILURE
RAM FAILURE
ROM 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 SKREEM’S microcontroller determines that an antenna circuit fault
has 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 at 65.5 millisecond
intervals.
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 written operation.
RAM FAILURE
When Monitored:
With the ignition on.
Set Condition:
The RAM fails a test that checks the RAM’s ability to retain memory.
ROM FAILURE
When Monitored:
With the ignition on.
Set Condition:
The RAM fails a test that checks the ROM’s ability to retain memory.
SERIAL LINK INTERNAL FAULT
When Monitored:
With the ignition on.
Set Condition:
The SKREEM fails an internal J1850 communication self test.
245
SKREEM
STACK OVERFLOW FAILURE
When Monitored:
With the ignition on.
Set Condition:
The microcontroller has exceeded its memory space limit.
POSSIBLE CAUSES
SKREEM INTERNAL DTC FAILURE
TEST
ACTION
APPLICABILITY
1
NOTE: This trouble code indicates an internal SKREEM fault.
With the DRBIII
t, read and record the SKREEM DTCs and then erase the SKREEM
DTCs
Perform 5 ignition key cycles, leaving the ignition key on for a minimum of 90 seconds
per cycle.
With the DRBIII
t , read the SKREEM DTCs.
Did the same SKREEM DTC return?
All
Yes
→ Replace and program the SKREEM in accordance with the
Service Information.
Perform SKREEM VERIFICATION TEST - VER 1A.
No
→ Test Complete.
