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 manually 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:
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 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.
