VVDI Prog is perfect tool to read MCU, ECU, IMMO. etc. And we received some feedback about VVDI Prog “Try frequency failed” error. Here is some suggestion.
1. BMW series 1 Try frequency failed?
Please check wiring diagram in VVDI Prog software again and re-welding the SCK clock line.
2. MCU RENESAS-V850 Try frequency failed
Test few more modules, if all still the same erro, it should be a problem with the device’s crystal oscillator. Please contact the seller you bought from to get repair process.
