Lonsdor K518ISE cannot Connect to Any Supported Car Model Solution

If the Lonsdor K518ISE can’t be connected to any supported car model, the main reason should be the OBD cable or little chance due to the device.

Here provide the method to test the OBD cable:

  1. Unplug the K518ISE main unit and turn it off
  2. Connect the DB25 cable(OBD cable) to k518ISE main unit, using a

multimeter and switch to the diode stalls

Pay attention that there are 3 connectors on the OBD cable:

Connector 1: connect K518ISE OBD port;

Connector 2: connect KPROG adaptor

Connector 3: connect the vehicle OBD port

  1. 3. Use the red pen to touch the metal part(as shown in pic 2 in red)

  1. Use the black pen to test the resistance of each pin of the vehicle

connector (As shown in pic 3) , make sure that you hold the vehicle connector

in the way just as the pic shows:


Pic 3: 16 pins on the vehicle OBD connector

PIN 1 and 8 should have no resistance; PIN2,3,4,5,6,7,9,10,11,12,13,14,15,16 should have resistance.

If all have no resistance, then it will be DB25 cable has problem; if the

measurement is all as it supposed to be, and the car models(those K518ISE

supported models) still can’t be connected, then you will need to send back the DB25 cable and the main unit for Lonsdor to check(if so, let us know, and we shall talk together about the solution and details)
