ECU Issues

Postby JHaltermann [OP] » Mar 08 2019, 2:02am

I recently went for an inspection (NY) and was told that none of my monitors were ready in order to pass the inspection. The mechanic said that there must be something drawing my battery down so that the ECU resets with every shutoff. I’ve changed ignition switch and starter trying to see if those were the issue but to no avail. So now I’m just curious if anyone had ran into a similar issue or knows a fix.

Welcome to the site.
Have your battery tested. If it is weak, that will keep some tests from running. Also be sure to have 1/4-3/4 tank of gas. Too full or empty can cause Evap test not to run.
When you have a moment, post up an introductory post and also a pic of your truck.
