Principles of Operation 

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. 

WDS will automatically attempt to retrieve the module configuration information from all modules, and from a 
backup location in the powertrain control module (PCM) when vehicle ID is carried out. If the module and the 
PCM do not contain correct information, the diagnostic tool will either request "As Built" data or display a list 
of items that you will need to instructionly configure. The diagnostic tool will program the module based on the

data you enter. 

There are three different methods that are used for module programming: 

z

programmable module installation (PMI)  

z

calibration update  

z

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 diagnostic tool to gather module option content from the 
old module. The diagnostic tool 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. 

Calibration Update 

Calibration update is used to install a new calibration and strategy into a module. The updates are usually issued 
to fix a concern in the module software and would normally be addressed by a technical service bulletin (TSB). 
This method has been used by the PCM for several years. Other modules will be adopting this strategy as well. 

Programmable Parameters 

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 Programmable Parameters 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 you may need to use programmable parameters 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 
backup data for each programmable module, as well as powertrain configuration information. 

If the diagnostic tool cannot retrieve module option content information from the suspect module, the diagnostic 
tool will attempt to extract backup information from the PCM VID block. 

The PCM VID block contains the factory settings for the configurable modules unless the PCM is flashed with 
a new calibration, in which case some PCM parameters may be modified.
