Symptom List:
TRANSPONDER (CYCLIC REDUNDANCY CHECK) CRC FAILURE
TRANSPONDER COMMUNICATION FAILURE
TRANSPONDER ID MISMATCH
TRANSPONDER RESPONSE MISMATCH
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be TRANSPONDER (CYCLIC RE-
DUNDANCY CHECK) CRC FAILURE.
When Monitored and Set Condition:
TRANSPONDER (CYCLIC REDUNDANCY CHECK) CRS FAILURE
When Monitored: At ignition ON and during Key Programming Mode.
Set Condition: This condition exists when 5 consecutive transponder signal transmis-
sions are sent to the SKIM with the correct message format but with invalid data.
TRANSPONDER COMMINICATION FAILURE
When Monitored: At ignition ON and during Key Programming Mode.
Set Condition: This condition exists when an invalid message format is received from the
transponder after 5 consecutive transponder read attempts.
TRANSPONDER ID MISMATCH
When Monitored: At ignition ON and during Key Programming Mode.
Set Condition: This condition exists when the transponder ID read by the SKIM does not
match any of those transponder ID's stored in the SKIM's memory.
TRANSPONDER RESPONSE MISMATCH
When Monitored: At ignition ON and during Key Programming Mode.
Set Condition: This condition exists when the transponder's secret algorithm result fails
to match the SKIM's result.
