So I originally had the first cts monitor and it worked great had all the pids and functioned as it was suppose to. Well I got into an accident back in June and once I finally got my car back in Nov my monitor stop working. I figured it was shorted out by the place that did the repair work since they didn't seem to be able to do anything else correct. Well I finally got the insurance to buy me a new one so I figured why not upgrade. Well now the cts2 is doing the same thing as my cts. After reading all the other post has anyone been able to figure out why the cts monitors are hit and miss?
