Action Code

Action Code

All software components (e.g. stored in the trip computer) have a Part Number and an action code. The action code is a one, two or three digit code which identifies a certain software package.

Any software package for the car can be ordered by using the action code. However, VIDA is configured so that if an action code for reloading is entered from the software manager, the mechanic will be linked to the replacement parts catalogue.

This does not apply to upgrades where these are missing from the replacement parts catalogue. A list containing the upgrade action codes can be found in the Technical Journals.

The following types of action code are available:
- Upgrading.
- PIN code.
- Reloading.
- Complete reloading.
- Add or remove functionality.

The upgrade action code is used to replace the software in a control module when there is a complaint and a solution to correct a characteristic. A list containing the upgrade action codes can be found in the Technical Journals.

The PIN type of action code is used to order a specific protected function. These are used for example for the immobilizer function when replacing the engine control module (ECM). Or for remote controls when replacing the upper electronic module.

Reloading type action codes are used when a control module has been replaced.

CAUTION:
- Software downloading is limited in that only one new control module can be replaced at a time.
- It is therefore important that only one control module is replaced, and that one reload is carried out for that control module before replacing the next control module.
- If two control modules are replaced at the same time, an incorrect configuration will be sent to the Volvo central database. The car cannot be reset without help from the helpdesk, which can take several days.

Complete reloading should be used if a previous download has been interrupted. VIDA recommends a complete reload as part of the process of restoring the car to the download situation. What differentiates this type of action code is that no verification of the software occurs before downloading. The error flag check does not occur during a total reload and therefore a total reload action code is used when others have failed. For a description of error flags, Software

The adds or removes function type of action code is used to expand or decrease functionality in the car. This is mainly carried out by modifying the Car configuration file in the central electronic module.

Modifying this file results in new functionality for the car. There are certain functions which also require software, such as when adding a control module to the car.

The "remove" function does not actually erase any software. It is a parameter in the Car configuration file which is reset so that the control modules in the Control Area Network (CAN) interpret the function as erased. There is only one occasion on which software is erased and that is immediately before new software is loaded to a control module. This is so that the earlier software does not interfere with the new software.
