Vcds Atmega162 Reflash Link -

The PCB of a HEX+CAN clone typically exposes a 2x5 (10-pin) ISP header. Map it to your USBasp:

The "VCDS ATmega162 reflash" is a niche but active corner of automotive diagnostics hacking. For a hobbyist, it is a challenging lesson in AVR programming, ISP hardware, and reverse engineering. For a professional mechanic, it is a false economy. vcds atmega162 reflash

Before erasing, create a backup of the current flash and EEPROM (saves calibration data): The PCB of a HEX+CAN clone typically exposes

Most VCDS clones have a pre-flashed bootloader. If the chip is not fully bricked, you might enter programming mode by shorting two specific pins (often MOSI and GND) while powering up. If the chip is locked (the lock bits are set), you cannot read the existing flash, but you may still be able to erase and write new code. For a professional mechanic, it is a false economy

You cannot reflash the ATmega162 via the USB port of the VCDS cable once it is bricked. You need an such as:
