Module Configuration
MODULE CONFIGURATIONDefinition 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.
Programmable Parameters
This method is used to configure parameters that may be modified. Not all features controlled by the module are listed in this configuration method. See 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 or equivalent Tester 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 VID block. The PCM VID block may contain 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.
As-Built Data Center
The As-Built Data Center maintains a record of the vehicle configuration in a database. The vehicle identification number (VIN) is required to obtain this information. 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. Only contact the As-Built Data Center when directed to do so by the diagnostic tool.
Configurable Modules
The vehicle contains the following configurable modules:
- SJB
- PCM
- ABS module
- instrument cluster
MODULE CONTROLLED FUNCTIONS
The smart junction box (SJB) is the multifunction electronic control module on this vehicle.
Principles of Operation
The SJB is located under the front passenger-side floor console. For removal information, see SMART JUNCTION BOX (SJB). For additional information on interior lamps and illuminated entry, see INTERIOR LIGHTING. For additional information on exterior lighting, see TROUBLESHOOTING (LIGHTING SYSTEMS). For additional information on power door locks, keyless entry keypad and RKE, see LOCKS, LATCHES AND ENTRY SYSTEMS. For additional information on the rear windshield wiper, see WIPERS AND WASHERS. For additional information on anti-theft, see ANTI-THEFT SYSTEM. For additional information on the climate control system, see CLIMATE CONTROL SYSTEM.

CUSTOMER PREFERENCE ITEMS
NOTE: If using the WDS or equivalent Tester, select Module Configuration and Programming, then follow the screen prompts.
NOTE: Make sure module is listed as supporting customer preference items and supports the specific item to be configured; see MODULE CONFIGURATION.
1. Select Service Bay Functions on the WDS or equivalent Tester.
2. Select the module that contains the customer preference item to be programmed. See MODULE CONFIGURATION.
3. Select Customer Preference Items on the WDS or equivalent Tester.
4. Select Module Option Content.
5. Select the item to be enabled or disabled.
6. Enable or disable the item as necessary to reflect the customer preference.
