Module Programming Methods: Notes

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

Some modules must be programmed as part of a repair procedure. If this procedure is not followed, the module will not function correctly and may set a number of diagnostic trouble codes (DTC)s, 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 cause concerns or faults.

The WDS automatically attempts to retrieve the module configuration information from all modules. If the module cannot communicate, the diagnostic tool either requests the As-Built data or displays a list of items that need to be manually configured. The WDS programs the module based on the data entered.

For diagnostic tool information, refer to the GENERAL PROCEDURES in this section.

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.
