Definition of Terms
Calibration update: Some modules are designed to be flashed or reflashed with completely 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 different from updating calibrations as no software is changed, only the options already contained in the software.
Some modules must be programmed as part of the repair procedure. If this procedure is not followed, the module does not function correctly and may set a number of diagnostic trouble codes (DTCs), including B2477 or P1639, which indicate that necessary data has not been programmed into the module.
Note. The vehicle must be stationary and level, with all accessories off, while configuring modules.
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, cause concerns or faults.
The diagnostic tool automatically attempts 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 either requests As Built data or displays a list of items that are needed to manually configure. The diagnostic tool programs the module based on the data entered.
For additional diagnostic tool programming procedures, refer to PROGRAMMABLE MODULE INSTALLATION .
There are 3 different methods that are used for module programming
- programmable module installation (PMI)
- calibration update
- programmable parameters
Some modules do not support all 3 methods.
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 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 the diagnostic tool is connected to the vehicle and allowed to identify the vehicle and obtain configuration data prior to any module removal.
Programmable Parameters
If a module that has been modified using programmable parameters needs to be installed, the PMI procedure maintains the parameters in their altered state if diagnostic tool is able to communicate with the old module during vehicle ID. Otherwise, you may need to use programmable parameters to return parameters to the altered state.
Configurable Modules
The vehicle contains the following modules that are configurable
- anti-lock brake system (ABS) module
- audio unit
- driver seat module (DSM)
- instrument cluster
- PCM
- restraint control module (RCM)
- smart junction box (SJB)

PROGRAMMABLE PARAMETERS INDEX REFERENCE
Using the Vehicle Communication Module (VCM) When the Original Module is Not Available
- Install the new module.
- Using the VCM and the latest version of the service function card, SELECT: Programmable Module Installation.
- Select the module being installed.
- Follow the on-screen instructions.
- SELECT: Retrieve Module Configuration - Old ECU and press trigger.
- Follow the on-screen instructions.
- The VCM attempts to retrieve the module data. If the module data is available, go to «STEP A»(ref-233032-S26966888102006052400000) . If the VCM displays: Call the As-Built Data Center, go to «STEP B»(ref-233032-S38707464602006052400000) .
Step A
- SELECT: Restore Configuration - New ECU. Press trigger.
- The VCM completes loading the retrieved data and displays Module Download Successful.
- Test the module for correct operation.
Step B
- Press the trigger.
- If the VCM asks for vehicle data, enter the vehicle data, then press store.
- The VCM asks for module data line 1. Enter the data and press store.
- The VCM then asks if there is an additional line of data available for that address. Select YES or NO depending on the information in the As Built Data Sheet.
- Repeat Steps 3 and 4 until the answer is NO for Step 4 .
- The VCM should show a screen stating that the module data was stored. Press the trigger.
- Follow the on-screen instructions.
- SELECT: Restore Configuration - New ECU. Press the trigger.
- The VCM completes loading the retrieved data and displays Module Download Successful.
- Test the module for correct operation.
Using the Vehicle Communication Module (VCM) When the Original Module is Available
- With the original module still installed, using the VCM and the latest version of the service function card, SELECT: Programmable Module Installation.
- Select the module being installed and press the trigger.
- Follow the on-screen instructions.
- SELECT: Retrieve Module Configuration - Old ECU. Press the trigger.
- Follow the on-screen instructions.
- INSTALL new module, SELECT: Restore Configuration - New ECU. Press the trigger.
- The VCM completes loading the retrieved data and displays Module Download Successful.
- Test the module for correct operation.
