Customer "SNAPSHOT"

The Northstar powertrain has an unique feature that allows a PCM snapshot to be recorded without being in on-board diagnostics by simply pressing two buttons on the CCDIC. This feature, called Customer Snapshot, records a complete set of PCM data parameters and inputs when the "OFF" and "FRONT DEFROST" buttons on the CCDIC are pressed simultaneously.

Customer Snapshot only works when the vehicle is NOT in on-board diagnostics. This feature can be very useful when it is difficult to reproduce a condition. When this occurs, the owner or driver may be instructed to take a Customer Snapshot while the condition is present and return to the repair shop for diagnosis when convenient.

A Customer Snapshot may be taken anytime the ignition is on and the vehicle is not in on-board diagnostics. While this is true, pressing the "OFF" and "FRONT DEFROST" buttons simultaneously for one second will cause a snapshot to be taken and the "SERVICE ENGINE SOON" MIL to be turned on for 2 seconds as confirmation that a snapshot was taken. This data may be retrieved by entering diagnostics, selecting PCM SNAPSHOT and viewing the P001 SNAPSHOT. (It will appear as a code snapshot with and code designation of P001, hence the P001 SNAPSHOT designation.)

The Customer Snapshot data will be overwritten if another Customer Snapshot is taken or if a PCM snapshot is taken while in on-board diagnostics.
