MODULE CONFIGURATION
Definition of Terms
Calibration Update: Some modules are designed to be flashed or reflashed with complete new software packages. This process of reflashing the module
is a calibration update.
Programmable Parameters: These are options contained within the existing software. These include items such as tire size, customer preference items
and anti-theft options. The current settings are downloaded from an existing module then uploaded to a new module. They can also be configured using
the diagnostic tool. Programming parameters is very different from updating calibrations as no software is changed, only the options already contained in
the software.
Module Programming Methods
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.
WDS or equivalent Tester 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 or
equivalent Tester will program the module based on the data entered.
For scan tool information, see general procedures. 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 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 (WDS or equivalent Tester) 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 to
connect the WDS or equivalent Tester 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.
