Symptom List:
ANTENNA FAILURE
COP FAILURE
EEPROM FAILURE
INTERNAL FAULTS
RAM FAILURE
SERIAL LINK INTERNAL
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:
EEPROM FAILURE
When Monitored: At ignition ON and during the SKIM programming process, which
programs SKIM's PIN the VIN, country code or additional keys.
Set Condition: This condition is set when an error occurs during programming the
SKIM's EEPROM. The other condition that causes this code to mature is an EEPROM I2C
link failure.
POSSIBLE CAUSES
SKIM INTERNAL DTC FAILURE
TEST ACTION APPLICABILITY
1Note: This trouble code indicates an internal SKIM fault.
With the DRBIIIt, read and record SKIM DTC's and then erase SKIM DTC's
Perform several key cycles, leaving the key on for a minimum of 30 seconds per cycle.
With the DRBIIIt, read SKIM trouble codes.

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.
