How to solve Lonsdor K518ISE can’t be connected to the supported car models

if your Lonsdor K518ISE can' t be connected to any supported car models, how to  solve?

Is it very possible because the OBD cable, or little chance due to the device?

OBD test cable testing method:
Step 1: Unplug the K518ISE main unit and turn it off
Step 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

Pic 1 3 connectors on OBD cable

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

Step 4: 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 )
