P1624

CIRCUIT DESCRIPTION
The customer-snapshot feature lets the customer store the powertrain control module (PCM) data when a driveability problem occurs. The feature permits several snapshots during each ignition cycle. When the customer requests the snapshot, the PCM stores the data, and sets DTC P1624. The PCM also illuminates the malfunction indicator lamp (MIL) for a specific length of time in order to tell the customer that the data has been stored.

CONDITIONS FOR SETTING THE DTC
The PCM receives a customer-snapshot request.

ACTION TAKEN WHEN THE DTC SETS
- The control module stores the DTC information into memory when the diagnostic runs and fails.
- The malfunction indicator lamp (MIL) will not illuminate.
- The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
- The driver information center, if equipped, may display a message.

DIAGNOSTIC AIDS
This DTC informs the technician that the customer has initiated the customer-snapshot function. The PCM will store up to 6 snapshots in the failure records before over-writing the first recorded snapshot. The customer-snapshot function may help to diagnose conditions which could not be duplicated during previous diagnosis.

If no other DTCs are set, the problem is most likely intermittent. Refer to Intermittent Conditions in Symptoms. Intermittent Conditions
