Symptom List:
PCM STATUS FAILURE
ROLLING CODE FAILURE
SERIAL LINK EXTERNAL FAULT
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be PCM STATUS FAILURE.
When Monitored and Set Condition:
PCM STATUS FAILURE
When Monitored: This condition is monitored at ignition ON and continuously during an
ignition ON cycle.
Set Condition: This condition exists when a PCM STATUS bus message was not received
from the PCM. Note: Failure maturity time is 20 seconds.
ROLLING CODE FAILURE
When Monitored: At ignition ON, after ignition ON during any rolling code handshake
that occurs with the PCM due to a SKIM or a PCM reset.
Set Condition: This condition exists when a PCM STATUS message is not received by the
SKIM within 3.5 seconds of transmitting what the SKIM believes to be a 'key code'
message to the PCM. the 'key code' sent by the SKIM may or may not be valid in this case.
SERIAL LINK EXTERNAL FAULT
When Monitored: At ignition ON, after ignition ON during any rolling code handshake
that occurs with the PCM due to a SKIM reset or a PCM reset, or during 'Secret Key'
transfers to the PCM.
Set Condition: This condition is set when the SKIM does not receive an expected bus
message transmission acknowledgement from the PCM after 3 transmit attempts.

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.
