Enabling EV-mode Button "H14 #27 to ground"

The EV-Mode Button is a standard part of the Japan and EU Prius but was not installed in the US versions, perhaps because of extended warranties in Ca due to AT-PZEV regulations and qualifications criteria. The US Prius is still entirely aware of the EV-Mode though it can never get the signal or command to enter or exit the mode because a wire, light and button are missing. EV-Mode is a very enlightening feature as it encourages the Prius to stay in it's electric mode for far longer than it normally would. CoastalTech.com has a well intigrated 3-wire EV-Button kit and [ someone] more information for "do it yourselfers".

Four things that cancle EV-Mode.

• Battery reaches 2 out of 8 battery bars worth of charge.
• Speed reaches 34mph.
  • EV-only driving regularly occures even at freeway speeds when there is ample battery energy.
• Accellerator peddle is depressed more than half to 3/4 of the way down.
• Pushing EV-Mode button.

Tachometer

No can do, unless you know otherwise, OBD info is probably as close as it gets.

Touch screen diags

• Hold "Info" button while turning the lights on and off 3 times.
• While in the 'Diagnosis Menu', pressing the upper-left corner than the lower-right corner on the screen will give you the 'Pdm' menu
• Tru the 3x light switch again while in Pdm screen.
