If this occurs, the driver might be corrupt, or the flash failed.

The "Opcom Firmware 1.99 Hex File" is largely a myth created by clone manufacturers. If your interface came factory-installed with version 1.99 and it works for your vehicle, leave it as it is. If you are trying to fix a broken interface, look for a verified instead, provided your hardware has a genuine, flashable PIC18F458 chip.

If you have verified that your interface contains a genuine Microchip PIC18F458 chip and you still choose to proceed with flashing a version 1.99 hex file, follow this technical procedure carefully. Prerequisites

If the flashing process is interrupted, or if the wrong hex file is used, the device can become permanently unusable ("bricked"). Opcom Firmware 1.99 Hex File
