How to solve Lonsdor K518ISE can't be connected to any car


This is tech support from obdexpress.co.uk for those uses with Landsor K518ISE failed to connect the machine to any car listed in K518ISE vehicle list.
OBD test cable testing method...here you go.
 
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

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 @obdexpress.co.uk know, and we shall talk together about the solution and details,thanks!)
