Pinpoint Test A : The Powertrain Control Module (Pcm) Does Not Respond To The Scan Tool: Notes

WARNING: This page is about a different car, the 2015 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.

Refer to ELECTRONIC ENGINE CONTROLS for schematic and connector information.

Normal Operation and Fault Conditions 

The PCM communicates with the scan tool through the Electric Vehicle (EV) High Speed Controller Area Network (HS-CAN). An Integrated Diagnostic System (IDS) session cannot be established if the PCM communication fails when attempting to identify the vehicle.
