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 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 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's 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.
As-
Built Data Center
The As- Built Data Center maintains a record of the vehicle configuration in a database. The vehicle's
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.
Inspection and Verification
1. Visually inspect for obvious signs of electrical damage. Refer to the following chart:
