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 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.
Transmission Identification Block
Some PCMs also contain a memory area called a transmission identification block. The PCM transmission identification block commonly stores solenoid body flow data. If the solenoid body information is not correct, transaxle damage or driveability concerns can occur. Refer to AUTOMATIC TRANSMISSION - 6F50/6F55 , or AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .
