Functions Display:A. Connect ECU module, special power supply to read and write ECU data, ECU clone, programming and adjustment.
B. GT105 provides uninterrupted power supply during the car battery replacement process to protect the car ECU data.C. OBD2 universal jumperD. After 2016, when all Ford smart keys are lost, GT105 cooperates with VVDI equipment (OBDSTAR, AUTEL) and other IMMO matching equipment to program the keys.All car keys lost matching—wake up the meter or wake up the IMMO ECU. (Support VAG 4th and 5th generation IMMO, Toyota ECU synchronization, auxiliary Mitsubishi key all-lost matching or all-lost remote control key setting, old Porsche Cayenne car for IMMO key learning.)E.VPW CANH CANL K-Line indicator light can judge the communication status between the vehicle and the diagnostic programming device. (If the connected device can determine whether the device can send communication, simply determine whether the diagnostic programming is normal.)F. IMMO AD Ford all lost smart keys, VVDI equipment (OBDSTAR, AUTEL) and other IMMO matching equipment. For all-loss matching, you need to disconnect the car battery, connect the negative pole of the battery via OBD5, and connect the 16 pin to the positive pole of the 12v battery.Example: Use the Xhorse Key Tool Plus Pad to match a new Ford model after 2017. In the state of all keys lost, the vehicle is in the alarm state, and the tablet cannot be used for matching. If you want to match the keys, you must release the IMMO state.If the vehicle has entered the IMMO state. Disconnect the positive pole of the battery as prompted by the device, and then connect the vehicle battery with the GT105 power adapter cable, as the picture shows.(In the process of key matching, the external 12V power supply is always maintained, no need to disconnect)Follow the instructions on the Xhorse Key Tool Plus Pad to match the keys.
G. All lost car keys match—wake up the meter or wake up the IMMO ECU.Porsche and VW 4th generation smart, 5th generation card key (model list: new A6L Touareg A4 Q5 A7) lights up the instrument, the key matching tool is connected for data collection. Some vehicle instruments do not light up, but data collection can also be performed, for example: A6L Q7.H.Toyota replaces the engine ECU, the IMMO ECU needs to be synchronized, or some key matching equipment can match all lost keys of Toyota vehiclesI. Mitsubishi key lost all matching or all lost remote control key settings.
J. IMMO key learning for old Porsche Cayenne
K. Outdoor operation power collectionWhen the locksmith or ECU engineer cannot get the 12V power supply in the outdoor operation, he can use the GT105 power adapter cable to obtain the 12V power supply from the car battery.Provides power to a 12V powered key cutter
