PINPOINT TEST QE: Electronic Throttle Control (ETC) System: Introduction
WARNING: This page does not describe the selected car, but rather 34 other vehicles, including the 2019 Lincoln Navigator, 2019 Lincoln Nautilus, 2019 Lincoln MKZ, 2019 Lincoln MKT, and 2019 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
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.
