Hi,
I haven't had a chance to fill out my signature yet. I have a 1997 XK8, conv. 4.0.

The problem I am having is I have used (2) different scan tools and neither will talk to the ECM. These are Snap On scan tools.

Has anyone else had this problem? I just installed a new battery. I had running pretty well, but it was surging and hard to start.

I don't want to continue to run it until I can get a scan/codes.

I would appreciate if anyone might be able to assist.
Thanks-Dan

 

Is the key in the RUN position?

Check the fuse for the permanent power to the Data Port.

In addition to the advice above, make sure the protocol is set to ISO 9141. Some scanners do not detect protocol automatically.

 

I'm having a similar problem with an icarsoft i930. Unfortunately, there's no option to select protocol. Been emailing customer service, but my Mandarin is non-existent and their English is shaky!

My Torque Pro app seems to work perfectly, however, but only covers very limited parameters.
