Two options are available when accessing the IMMO function:

 Smart Mode – the IM600 tablet will read the vehicle information and analyze the

IMMO part information automatically.

 Expert Mode – user can make selections step by step to locate the IMMO part.

 Procedures before getting started:

1. Connect the OtoFlash to the vehicle’s DLC via the main cable for both

communication and power source.

2. Connect the OtoFlash to the tablet via BT pairing, or USB connection.

3. Connect the IM600 tablet to the included programmer UP400 via USB cable.

4. Dismount the ECU module from the vehicle

5. Connect the ECU module to the Emergency coil stretched out from COM7.

6. Connect one end of the included OBD cable to the IM600 tablet, while the other

end needs to be connected to the wire harness stretched out from COM8 on the

ECU module. The wire harness is not included, you could DIY.

7. Make sure the user has access to WiFi service in case you need to send the

operation data.

NOTE

Illustrations used in this manual are samples, and the actual testing screens may

vary by vehicle. Observe the menu titles and on-screen instructions to make correct

selections and operations.
