ECU and SRS Configuration Reset Script for Toyota / Lexus (iProg Pro)
The configuration (vehicle specification) reset script is designed for operation with ECU (Electronic Control Unit) and SRS (Supplemental Restraint System / Airbag) modules in Toyota / Lexus vehicles. The solution is intended for vehicles manufactured approximately from 2016 and is used in conjunction with the iProg Pro programmer..
The script only works with original iProg Pro programmer! Please write Serial Number and UID in the order.
The scripts allow correct clearing and restoration of configuration data without causing conflicts between vehicle systems. All operations are performed via memory dump.
Supported Modules and Technical Details
SRS support:
- SRS modules based on Renesas R7F701A223 microcontroller
- Dump-based operation
- No similar issues observed on other hardware revisions
ECU (Engine Control) support:
- Engine control units with 95320 EEPROM
- Dump-based operation
The script is optimized to eliminate configuration conflicts between the engine ECU, instrument cluster, and active safety systems.
Application Scope and Solved Issues
Typical scenario: after resetting the configuration (vehicle specification) in the instrument cluster, the adaptive cruise control stops working correctly. When activated, related error messages appear on the dashboard due to configuration mismatch.
After applying this script:
- adaptive cruise control is correctly converted to standard cruise control;
- configuration conflicts within the engine ECU are eliminated;
- SRS module errors related to the PCS (Pre-Collision System) are removed.
The script provides a complete and consistent restoration of configuration data across all involved systems.
