Note
When erasing DTCs you will be asked to start the vehicle twice and let it idle before DTCs will be readout from all control modules once more as a final check.
The tab contains information and functions for Diagnostic Trouble Codes (DTC) that are relevant for the selected vehicle. All DTCs detected at the vehicle readout are listed here, as well as any other possible DTCs that can occur in the currently selected vehicle.
The DTCs are divided into three lists according to their status. Select list by using the following three buttons:
See the subsections below for information about each list.
All DTCs that are related to the component selected in the component list are always presented on the top of the list, marked in bold. The DTCs that are not related to the selected component are shown as well but in regular font below the component related DTCs.
List of confirmed DTCs
The list of confirmed DTCs is pointing out detected faults that are confirmed or are likely to be confirmed by the in-vehicle DTC test. The list is ranked in descending order which means that it is always the DTC at the top of the list that is most likely the one to point out the problem. You should always start fault tracing with the first DTC in the list and work your way down.
Faults pointed out by confirmed DTCs are usually more or less lasting faults that occur during operating and ambient conditions that the customer often will be within. They are so large, prolonged and high-frequent that they are causing symptoms that the customer almost for sure will recognize, be bothered by and want to have fixed. They are normally persistent, repeating and associated with high traceability and low acceptance by the costumer. The conditions in which these faults occur and cause symptoms that the customer will notice are usually enough known to be able to repeat e.g. in a workshop prior to troubleshooting and repair. They are therefore normally easy to verify and confirm.
The DTCs in this list can have one of the following statuses, based on the latest vehicle readout:
|
Status indicator |
Status name |
Description |
|---|---|---|
|
|
Confirmed |
Long duration fault detected many times by the in-vehicle DTC test. These faults have been detected long enough and enough number of times in order to be regarded as permanent. The DTCs associated with these faults are therefore regarded as confirmed. These faults have been detected by a selective and accurate detection principle during stable, known and controlled conditions. The advantage of detecting faults in this robust and accurate way is that they can be considered as verified and confirmed by the in-vehicle DTC test. |
|
|
Pending |
Long duration fault detected one or more times by the in-vehicle DTC test. These faults have been detected long enough but not enough number of times in order to be regarded as permanent. The DTCs associated with these faults are therefore not yet regarded as confirmed. |
|
|
Failed |
Long duration fault detected one time by the in-vehicle DTC test. These faults have been detected long enough but not enough number of times in order to be regarded as permanent. The DTCs associated with these faults are therefore not regarded as confirmed. |

List of unconfirmed DTCs
The list of unconfirmed DTCs is pointing out detected faults that are not confirmed by the in-vehicle DTC test. The list is ranked in descending order which means that it is always the DTC at the top of the list that is most likely the one to point out the problem. You should always start fault tracing with the first DTC in the list and work your way down.
Faults pointed out by unconfirmed DTCs are usually temporary faults that occur during operating and ambient conditions that the customer seldom will be within. They are far from so large, prolonged and high-frequent that they are causing symptoms that the customer will recognize, will be bothered by and want to have fixed. They are normally transient, sporadic and associated with low traceability and high acceptance by the customer. The conditions in which these faults occur and cause symptoms that the customer will notice are perhaps not sufficiently well known to be able to repeat e.g. in a workshop prior to troubleshooting and repair. They could therefore be difficult to verify and confirm. However, they usually do not occur randomly, so if enough knowledge about them is available they will be possible to repeat.
The DTCs in this list can only have the following status, based on the latest vehicle readout:
|
Status indicator |
Status name |
Description |
|---|---|---|
|
|
Unconfirmed |
Short duration fault detected by the in-vehicle DTC test. These faults have not been detected long enough and not enough number of times in order to be regarded as permanent. The DTCs associated with these faults are therefore not regarded as confirmed. Please note that these faults may not have been detected in a robust and accurate way with a completely selective and precise fault detection principle during stable, known and controlled conditions. However, the advantage of also detecting faults in this way is that more fault indications can be logged and available for advanced fault tracing in VIDA. |
Note
Note
DTCs that have only reached the status unconfirmed are not confirmed by the in-vehicle DTC test. As the DTCs are not confirmed they are not reliable enough to be used as a base for ordinary fault tracing. Unconfirmed DTCs are intended for advanced fault tracing performed by highly skilled technicians on faults that are difficult to identify and locate.

List of all DTCs
In this list you can see all DTCs that exist for the selected control module in the component list. The information in this list is not affected by the vehicle readout but can be used as a source of reference information.

By clicking a DTC in one of the lists, the DTC Extended Information window is opened. These functionalities are used to perform advanced fault tracing on vehicles with faults that are difficult to identify and locate.
