I wish to check for any ECM Trouble codes and am looking for some info on carrying out a straightforward check using the Tech 1.

Please note that I have placed a jumper wire across points A and G of the ALDL connector and have 3 CCM TC's - H72, H74 and H22. I am aware of these and know the reasons why they occurred.

Any help with how to use the Tech 1 to interogate the ECM would be much appreciated.

Thanks,
