The corresponding connection method for each module with PCMTuner:

When using OBD or OBD-vr read/write functions in vehicle, it is advisable to use battery support.

On some diesel engines it is advisable to use scan tool and record any injector coding.

  • Not all OBD can be connected with breakout on Bench as they rely on other components in car such as IMMO to allow programming.
  • Most MED/EDC/MEG17 ECU that can be read in OBD can also be read in Bench with module 71.
  • Not all ECU’s support identification with OBD-vr. You may need to use scan tool to get ECU information to find ORI file.

Bench: direct connection to ECU header pins on bench

BSL: Connection to ECU and to PCB (ecu opened) (expert)

OBD: Connection via Vehicle OBD socket

OBD-vr: Connection via Vehicle OBD socket, Virtual read only, or write only

Check: PCMTuner Module Connection Instruction
