JAC JS6 FS32K144 Mileage Restoration & Dashboard Repair Script (SWD Protocol)
This professional-grade FS32K144 programmer script is specifically developed for JAC JS6 instrument cluster repair and mileage restoration. It provides a reliable solution for automotive electronics specialists who need direct access to dashboard data for diagnostics, recalibration, or restoration tasks.
The script only works with original iProg Pro programmer! Please write Serial Number and UID in the order.

Designed to work with the NXP FS32K144 MCU, the script operates via the SWD (Serial Wire Debug) protocol, ensuring low-level communication with the microcontroller. This makes it an essential tool for advanced JAC JS6 dashboard repair where standard OBD solutions are not applicable.
Key Features:
- Full support for JAC JS6 instrument cluster EEPROM operations via FlexRAM
- Read and write FlexRAM (configured as EEPROM in this module)
- Integrated mileage calculator script for fast and accurate data adjustment
- Software-implemented SWD communication protocol
Technical Specifications
The script enables stable reading and writing of the 4KB FlexRAM memory area. Due to the software-based SWD implementation, the process takes approximately 3 minutes for a complete read/write cycle, ensuring safe and consistent data handling.
Connection Guide (S32K144 SWD Pinout):
Connection is performed directly on the instrument cluster PCB using a 5-wire interface:
- GND
- VCC
- SWDIO
- SWCLK
- RESET
Open the program and click “Help” -> “About”.
