Pinpoint Test QA: Unable To Activate Self-Test/Network Communication Error: Introduction
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2016 Lincoln Navigator, 2016 Lincoln MKZ, 2016 Lincoln MKX, 2016 Lincoln MKT, and 2016 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- unable to communicate with powertrain control module (PCM)
- unable to activate the PCM self-test
- incorrect self-test procedure
- harness circuits: ISP-R, PCMRC, PWRGND and VPWR
