Pinpoint Test QE: Electronic Throttle Control (Etc) System: Introduction

This pinpoint test is intended to diagnose the informational PCM DTCs

The informational DTCs are the result of the failure mode effects management (FMEM) operating strategy that maintains limited vehicle function in the event of a PCM, harness or component concern.

Circuit DTCs can be accompanied by the informational DTCs and should be diagnosed first.

Informational DTCs without circuit DTCs may or may not indicate the actual concern and should be diagnosed as a symptom.
