OBD II Scan Tool (Not 95 MY)
The OBD II Scan Tool is designed to access the memories
of the engine and transmission control units to monitor
and extract data relative to emissions control.
The following types of data may be accessed:
Current Powertrain Data
Monitor Freeze Frame Data
Request Trouble Codes
Clear Trouble Codes
Request Oxygen Sensor Test Results
Monitor Oxygen Sensors
Display Pending Trouble Codes
Request On-Board Monitoring Test Results
Examine Readiness Tests
Malfunction Lamp Status
The data to be monitored is selected from the OBD
11
main
menu.
For example if Monitor Freeze Frame Data is selected, the
system will display up to 11 parameters which are always
recorded when a fault code is logged. The parameters are
as follows:
0 : SUPP Supported
2 : FCFF Fault Causing Freeze Frame
3 : FSS Fuel System Status
4 : CLV Calculated Load Value
5 : ECT Engine Coolant Temperature
6 : STFT-B1 Short Term Fuel Trim - bank 1 (Cyl

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). Svvitch on
the ignition. After communications are established,
the OBD
