WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2015 Lincoln Navigator, 2015 Lincoln MKZ, 2015 Lincoln MKX, 2015 Lincoln MKT, and 2015 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
