| CUSTOMER SNAPSHOT | |
| When not in diagnostics, a snapshot of PCM data and inputs may be taken by simultaneously pressing the 'OFF' and 'FRONT DEFOG' buttons on the CCDIC. The 'SERVICE ENGINE SOON' MIL will be illuminated while the 'OFF' and 'FRONT DEFOG' buttons are held to confirm a snapshot has been taken. After a customer snapshot is taken, the data may be retrieved in PCM Snapshot and will be stored as a P001 Snapshot. |
