CMDFlash is Flashtec SA’s ECU and TCU programming system. Available methods and functions depend on the controller, configuration and software licence. Flashtec lists OBD, bench, boot and BDM capabilities, with support for a range of processor and communication families.
Working methods
- OBD: communicates through a supported diagnostic connection, using protocols that may include K-line, CAN or Ethernet depending on application.
- Bench: connects to a supported control unit directly through its connectors.
- Boot and BDM: provide direct access for supported controllers and can require opening the unit and using appropriate adapters or probes.
The image shows an interface labelled MPC5xx BDM, OBDII K, CANBUS and PWM; do not assume that every CMDFlash configuration offers the same connections or coverage.
Licences and workflow
Flashtec offers Master and Slave configurations and optional capabilities. Slave configurations handle encrypted files with a Master relationship, subject to the particular package. Check the current application list, cable, subscription and supported operations for the exact ECU and software version. The supplier also lists diagnostic, logging and performance-test functions for applicable configurations. Map3D is separate calibration software.
Use the relevant instructions and stable power supply, and preserve an appropriate backup when the protocol allows. Read, virtual read, write and cloning are separate functions and may differ by controller.
