  • SID803A
Simos PCR2.1 supports:
  • Standard flash file
  • KESS V3/Trasdata flash read
Working with the Module

Select the vehicle brand and the exact ECU or TCU model. Where multiple processor variants are available, select the correct PowerPC or Tricore MCU version.
Upload the required flash or EEPROM file shown by the module. After processing is complete, download the modified immobilizer-off file.
Important Notes:
  • Always select the exact control-unit and MCU variant.
  • Upload the correct file type required by the selected module.
  • Options marked “Testing” are in test mode but functional so far acording to feedbacks.
  • Always keep an unmodified backup of the original file.
  • After writing the modified file, verify ECU or TCU operation using suitable diagnostic equipment.
