Having purchased a 2017 Ridgeline which employs VCM, which I detest, I defeated the VCM by biasing ECT1. I use the Bluedriver and App to monitor the engine coolant temp to ensure the temp stays <167F. The Bluedriver powers up and links to my iPhone Bluedriver App reliably, and provides very simple file sharing. I also like the built in firmware update capability! The Bluedriver and App is an outstanding monitoring unit!!
