| − | == Disabling Traction Control ==
| |
| − | '''WARNING: The shop manual apparently states in no uncertain terms that this procedure must NOT be used to drive the car as damage to the transmission could occur due to traction control being defeated.'''
| |
| − | * Follow the sequence below (quickly - within 60 seconds)
| |
| − | * Set Ign switch to ON, not READY (Power button twice, no brake)
| |
| − | * While still in "P" fully depress the gas pedal two times.
| |
| − | * Select "N" fully depress the gas pedal two times.
| |
| − | * Select "P" fully depress the gas pedal two times.<br>(LCD display will indicate a !Car! in upper left corner of screen)
| |
| − | * Turn key directly to "start" to start the engine (brake+start button)
| |
| − | It forces the ICE to run continuosly and defeats the traction control system. Normal operation returns after turn off and reboot. Unlike EV-Mode this is '''strictly a diagnostic function and should not be used under normal situations'''.

| − | == Enabling EV-mode Button "H14 #27 to ground" ==
| |
| − | See more Prius EV fun on the [[EAA-PHEV:Prius PHEV]] page.
| |
| − | | |
| − | 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 its electric mode for far longer than it normally would.
| |
| − | It will normally drive 1 to 2 miles and up to 3 miles on a fully charged battery, after which it must restart the engine and use gasoline to recharge the battery.
| |
| − | It is not a good idea to fully cycle the battery often as this decreases any battery's life and is not helpful for mileage if used improperly. If used correctly is can be advantagious for times when you know you won't need to start the engine. It's also fun for showing off and offers a small glimpse of the potential of electric vehicles.
| |
| − | | |
| − | The ev-mode function itself is activated and deactivated by grounding the H14 #27 pin on the HV ECU located behind the glove box(s).
| |
| − | [http://www.coastaletech.com CoastalTech.com] <!--(321 727 8457)-->(ph) has a well integrated 3-wire EV-Button kit with easy instructions or [http://www.calcars.org/prius-evbutton-install.pdf prius-evbutton-install.pdf] from [http://www.calcars.org calcars.org] and [http://www.vfaq.net/mods/EV-button-Y.html EV-button-Y.html] from [http://www.vfaq.net vfaq.net] have more information for "do it yourself" kind of people like me. I also found a [http://www.scubadivervideo.com/Files/factoryEV.pdf factoryEV.pdf] by ScubaX at [http://priuschat.com/Factory-EV-Switch-Install-t11338.html PriusChat] which I had hoped would lead to the ev-status illumination solution, but instead simply found that the dimmer switch white/black stripe wire to be ground(-) and the grey wire to be illumination control.
| |
| − | I'm looking for the steering pad wire diagram as I'd like to use the recirculation button as the ev-button, but it's probably not a simple ground.
| |
| − | | |
| − | Four things that cancel EV-Mode.
| |
| − | * Battery reaches 2 out of 8 battery bars worth of charge.
| |
| − | * Speed reaches 34mph.
| |
| − | ** EV-only driving regularly occurs even at freeway speeds when there is ample battery energy.
| |
| − | * Accellerator pedal is depressed more than half to 3/4 of the way down.
| |
| − | * Pushing EV-Mode button.
| |
| − | | |
| − | Things you need to add the feature.
| |
| − | * '''22 gauge wire''', about 6 feet.
| |
| − | * Standard Philips screwdriver.
| |
| − | * Small Jewler's screwdriver.
| |
| − | * Soldering may be required.
| |
| − | * 1/2 to 3 hours of time.
| |

| − | ===EV-Mode and your Warranty===
| |
| − | * [http://groups.yahoo.com/group/priusplus/message/495 Regarding your warranty] - Yahoo PriusPlus post.
| |
| − | ** http://www.sema.org/main/semaorghome.aspx?ID=50096 '''The Law'''
| |
| − | ** Federal law sets forth requirements for warranties and contains a number of provisions to prevent vehicle manufacturers, dealers and others from unjustly denying warranty coverage. With regard to aftermarket parts, the spirit of the law is that warranty coverage cannot be denied simply because such parts are present on the vehicle, or have been used(see [http://www.sema.org/Main/SemaOrgHome.aspx?ID=50100 Attachment A]).The warranty coverage can be denied only if the aftermarket part caused the malfunction or damage for which warranty coverage is sought. Disputes in this area usually boil down to arguments over facts and technical opinions, rather than arguments over interpretations of the law.
| |
| − | | |
| − | == Enabling even more Electric Vehicle features ==
| |
| − | Those features which you may associate with Hybrids may actually be electric vehicle features such as no idling, quiet operation, and regenerative braking.
| |
| − | Unfortunently, as of yet many of the greatest aspects of battery electric vehicles, or BEVs are not available in current Hybrids.
| |
| − | The EV-Button still doesn't allow you to recharge the batteries with electricity from a fuel source of your choice. Though it does hold the potential of a fuel choice which is already widely available and potentially renewable. By Plugging-In to an electrical outlet you can dramatically improve your ''gas'' mileage. The Grid is more than capable of supporting a large number of BEVs or PHEVs before it would require additional capacity, in fact it may help to ''load balance'' the grid.
