Module Configuration

MODULE CONFIGURATION

Principles of Operation
Some modules support the ability to change specified factory configuration settings and preset preference items. The process used to change the settings and customer preference items is module configuration. There are two different methods of module configuration:
- programmable module installation (PMI)
- customer preference items

There are three storage locations for module configuration information. One primary storage location and two secondary (or backup) storage locations.
- Primary location is the memory of the specific module.
- First backup location is the VID block memory of the powertrain control module (PCM).
- Second backup is the As-Built Data Center.

During PMI, the WDS or equivalent Tester will attempt to extract the module configuration information from the module to be changed. If this is unsuccessful, the WDS or equivalent Tester will use the first backup and attempt to extract the module configuration information from the VID block in the PCM. If this also fails, the WDS or equivalent Tester will display instructions to contact the As-Built Data Center. Contact the Mazda Technical Hotline if this message appears.

Programmable Module Installation (PMI)
The PMI configuration method is used when a new programmable module is to be installed. During the PMI routine the WDS or equivalent Tester attempts to gather two pieces of information:
- option content information from the old module (module configuration and customer preference settings)
- the vehicle identification number (VIN) from the PCM

During PMI the WDS or equivalent Tester first looks to the PCM for the VIN of the vehicle. Once the VIN is retrieved the WDS or equivalent Tester will carry out a self-test of the suspect module to determine if the module has been configured.
- If DTC B2477 is present the module does not contain complete configuration information. The PMI routine will then halt and give instructions on how to proceed.
- If DTC B2477 is not present the module will allow the WDS or equivalent Tester to retrieve its option content information. The WDS or equivalent Tester will then store the option content information and the VIN.

The WDS or equivalent Tester can store the combined option content information and VIN for only one module at a time. Once information is stored, the WDS or equivalent Tester cannot be used to retrieve any other option content information without erasing the previous option content information. Make sure the new module is on hand for installation before retrieving option content information data from the old module.

After the new module is installed, use the WDS or equivalent Tester to restore the option content information into the new module.

Vehicle Identification (VID) Block

NOTE: When carrying out a PMI routine on any non-PCM module, use the OBD II cable.

NOTE: Flash programming powertrain calibrations onto the PCM is different than PMI. It has no effect on the backup data in the VID block memory area of the PCM.

The PCM contains a memory area called a vehicle identification (VID) block. A portion of the VID block is used to store the backup data for each programmable module on the vehicle.

The VID block is the first backup of information when using the PMI configuration method. If the WDS or equivalent Tester cannot retrieve option content information from the suspect module, the WDS or equivalent Tester will attempt to extract backup information from the VID block of the PCM.

The VID block is not related to or affected by the powertrain calibration information stored in the PCM. If a new powertrain calibration has been flashed onto the PCM, the VID block will not be affected. If using the PMI routine to install a new PCM, the WDS or equivalent Tester will reprogram only VID information. The engine calibration information may still need to be flashed. For more information, contact Mazda Technical Hotline for flash programming information.

As-Built Data Center
The As-Built Data Center keeps a record of the vehicle configuration in a database that is retrievable using the VIN. The As-Built Data Center records the applicable module configurations stored in each module before the vehicle leaves the factory. The As-Built Data Center will always reflect the original build of the vehicle as it left the factory. Call the Mazda Technical Hotline if instructed to contact the As-Built Data Center by the WDS or equivalent Tester.

Customer Preference Items
This method is used to enable or disable module-controlled items or systems to suit the preference of the customer. Not all features controlled by the module are listed in this configuration method. Refer to the Module Configuration Index in this section for a list of features for each module.

If a feature is changed using the customer preference items configuration method, the changed information will not be stored in the PCM VID block. The VID block will retain the original settings as they were recorded when the vehicle left the factory.
