Hi all. I am trying to read codes from my 172 ph1 using a Sonde CAN clip running V178. The clip software loads fine, detects my clip and allows me in. When I run the scan tool the progress bar goes to the end and then I get the below message, unable to establish connection. Ignition is on so don’t know what’s up. This is the first time Ive used clip and am unable to interrogate anything. Correct car is selected. Any ideas would be greatly appreciated as this is doing my swede in!...
