Principles of Operation: Notes
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique modules for one vehicle line. These modules must be configured when replaced as part of a repair procedure. Configurable modules should not be exchanged between vehicles since the settings are unique to each vehicle. Failure to configure a new module may result in incorrect operation and/or DTCs setting.
The following are the 3 different methods of configuration:
- Programmable Module Installation (PMI)
- Module reprogramming ("flashing")
- Programmable parameters
Some modules do not support all 3 methods.
