If failed to read Hyundai SIM2k-47 ECU with PCMTuner via module 40, you can work on bench with obd breakout cable.
Bench pinout of module 40 for ecu sim2k-47 Hyundai
On bench worked fine. You need 120 ohm between CAN H and CAN L it should read. Connect GND on Pin 9.
Connect this way, also you need 120 Between CAN H and CAN L or get a good obd breakout cable with inbuild can resistor.
“I was able to read obd bench by using k line ; h and l pins I found from diagram and also 120 between can h and l . I read awesome but when I wrote the mod file the ecu get bricked and I couldn’t recover it. So I don’t recommend any to use this obd with writing better boot with ktag.”
