Application Scope
Typical Use Cases
The script is used when system conflicts appear after resetting or changing the configuration of other electronic modules in the vehicle.
Practical Example
After resetting the instrument cluster configuration using another OBD2/CAN script:
- Adaptive Cruise Control (ACC) stops functioning
- Error messages related to cruise control appear on the instrument panel
- The ECU continues to expect adaptive cruise control parameters that are no longer present
Problem Resolution
After performing a configuration reset directly in the ECU using this script:
- The ECU correctly reinitializes the vehicle configuration
- Adaptive Cruise Control is replaced by standard cruise control
- Cruise control–related errors are eliminated
- Conflicts between the engine ECU and other vehicle systems are fully resolved
