Principles of Operation
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 improper operation and/or DTCs setting.
The 3 different methods of configuration are
- Programmable Module Installation (PMI)
- Module reprogramming ("flashing")
- Programmable parameters
Some modules do not support all 3 methods.
