Getting Ready

  • Park the vehicle in a location with good cell service and out of the way of traffic.

  • Connect the OBD2 side of the ENet cable to the OBD2 port found on the driver's side next to your left kick panel, usually located upside-down on the panel near the brake pedal.

  • Connect the other side of the ENet cable to the adapter and plug the adapter into the iPhone.

  • Verify the connection by going to your device's Settings and ensuring you see the "Ethernet" adapter under your Wi-Fi and Bluetooth entries.

  • Go to Settings → USB LAN interface. Make sure you see the IP Address and Subnet populated. Note: This can take up to one minute to set up once everything is connected.

  • Turn your ignition into Accessory Mode.

While extensive research and development have been dedicated to ensuring that M-Flasher is the safest and most reliable flashing solution, the nature of modifications entails a potential risk of errors that may immobilize a vehicle temporarily. Therefore, it is advisable, during any software or hardware upgrade, modification, or enhancement, to legally park your car in a way that allows it to remain stationary in case diagnostics are needed.
