SYMPTOM
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 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.

POSSIBLE CAUSES
- Hard SKIM VIN mismatch
- PCM EEPROM DTC present
- SKIM communication link failure
- SKIM EEPROM failure
- SKIM PCM failure
- SKIM PCM problem
- SKIM unidentified problem
- SKIM VIN mismatch
- VIN does not match
- VIN mismatch not cleared
