Reading Detailed Diagnostic Data

General information about Reading





- Ignition on.
This function is used to Read the diagnostic data from the Control module in the background. If the VIDA log function is activated while the read out is taking place, all data that is read will be logged. The VIDA log function allows logs to be saved or read. This makes it easier to analyze data or to include the log files in a report for example.

- VIDA log function activated (log status on).

NOTE: If this has not already been done, exit this procedure. Select vehicle profile and set the logging status to On.

If the VIDA log function is already activated and has previously logged other activities which are not required, exit this procedure and log off VIDA. The existing log can then be removed. Delete the log and close it. Then log on to VIDA again.

Do you want to start Reading ? The data read starts automatically when YES is selected.


Reading the engine control module (ECM) diagnostic data

Finishing the Read
The Read is now complete.
Exit this procedure. Log off VIDA. The completed log can now be printed or saved.
Save the log to a disc or save it locally. To save it locally, name the file vehcom.log under C:\volvo\logs.

Communication fault







Communication has been interrupted for one of the following reasons:
- Ignition switched off.
- The switch is not in position for VCT 2000.
- VCT 2000 disconnected from Data Link Connector (DLC).
- VCT 2000 disconnected from VIDA cart/switch.
- Communication problems in VIDA application or in car.

Check therefore:
- that the ignition is on and switch is in correct position for VCT 2000.
- that battery voltage (system voltage) is normal (approximately 12 V). If necessary a battery charger can be connected during the test.
- that VCT 2000 is correctly connected to VIDA cart/switch and Data Link Connector (DLC).
- that VCT 2000 and wiring is fault-free.

Try to establish communication again or exit Reading Diagnostic Trouble Codes (DTCs). Depending on the communication fault, select one of the following alternatives.
- Try again.
- Fault-trace more comprehensively for the communication problem that has occurred. Checking Communication Faults
- Exit fault-tracing/read from next system.
