Description and Operation
MODULE CONFIGURATION
Some modules must be programmed as part of the repair procedure. If this procedure is not followed the module will not function correctly and may set a
number of DTCs, including B2477 or P1639, which indicate that some necessary data has not been programmed into the module.
Modules that need programming should not be exchanged between vehicles. In most cases the parameter values or settings are unique to that vehicle, and
if not set correctly will cause concerns or faults.
Some programmable parameters, such as belt minder on/off, can be changed from the factory setting at the customer's request.
Worldwide Diagnostic System (WDS) will automatically attempt to retrieve the module configuration information from all modules. If the module
cannot communicate, the diagnostic tool will either request As-Built data or display a list of items that will need to be manually configured. The WDS
will program the module based on the data entered.
There are three different methods that are used for module programming:
-
programmable module installation (PMI)
-
calibration update
-
programmable parameters
Some modules do not support all three methods.
Programmable Module Installation (PMI)
The programmable module installation (PMI) method is used when a new programmable module is installed on the vehicle. It is no longer necessary
to command the WDS to gather module option content from the old module. The WDS automatically obtains any available module option content
information from the old module during the vehicle ID routine that runs when the diagnostic tool is initially connected to the vehicle. It is important
that you connect WDS to the vehicle and allow it to identify the vehicle and obtain configuration data prior to removing any modules.
Programmable Parameters
Programmable Parameters Index
This method is used to configure parameters that can be modified in service. These are typically at the preference of the customer. Not all features
controlled by the module are listed in this configuration method. Refer to the Module Configuration Index for a list of features by system.
If a module that has been modified using programmable parameters needs to be installed, the PMI procedure will maintain the parameters in their
altered state if WDS is able to communicate with the old module during vehicle ID. Otherwise, programmable parameters may be needed to return
them to the altered state.
Vehicle Identification (VID) Block
Some PCMs contain a memory area called a vehicle identification (VID) block. The VID block is used to store powertrain configuration information.
As-Built Data Center
The As-Built Data Center maintains a record of the vehicle configuration in a database. The vehicle VIN is required to obtain this information. The
