Accessing Freeze Frame Data

Accessing Freeze Frame Data

The freeze frame data is vital in analysing unresolved trouble codes. If an emissions related trouble code occurs, complete a diagnostic trouble code report form including the vehicle data, logged trouble codes and the freeze frame data. Fax a copy of the form to Aston Martin Service Operations Department who will assist in resolving the concern.

To access freeze frame data, proceed as follows:

1. Switch on the PDU and select 'Engine Diagnostics.
2. Select 'OBD II Scan Tool'. The scan tool software will load and the 'Cable Setup' screen will appear.
3. Connect the PDU to the lower diagnostic socket using the multi protocol adaptor (MPA). Switch on the ignition. After communications are established, the OBD II Main Menu will appear.

4. Select 'Request Emission Trouble Codes' and press the 'tick' icon.

5. Any logged diagnostic trouble codes will be displayed on the screen (e.g. 0:P1243). Record both the list number (e.g. 0, 1, 2, etc) and the logged 'P' codes (e.g. P1243, etc).

6. Press the 'tick' icon and return to the OBD II main menu.

7. Select 'Monitor Freeze Frame Data' and press the 'tick' icon.

8. The numeric keypad screen will appear. Enter the list number noted in step 5 for the fault code to be investigated and press the 'tick' icon.

9. The 'Select PIDS to Monitor' screen will appear.
