CONNECTION METHOD GUIDE
OBD / BENCH / BOOT Mode Explained
Different PCMflash modules require different connection methods. This section helps customers understand the basic difference before they contact you.
OBD Mode
Connect through the vehicle diagnostic port when the ECU or TCU module supports OBD read/write. It is convenient and does not usually require removing the control unit.
- Fast vehicle-side access
- Good for supported read/write jobs
- Depends on ECU protection and module coverage
BENCH Mode
Connect directly to the ECU or TCU connector outside the vehicle. It is often used when OBD is not available or when the module requires a direct connection.
- Stable direct connection
- Often used for ECU/TCU repair and cloning
- Requires correct cable and power supply
BOOT Mode
Use lower-level bootloader access for selected flash, EEPROM, unlock or recovery operations. This method is more technical and must follow the correct wiring.
- Useful for advanced ECU/TCU work
- May support EEPROM or recovery operations
- Requires more technical experience
