How do I get my EV to engage?

I am having similar issues with a different symptom. I installed the kit, the pin is all the way down (can see it at the same level as the other pins.

When I hold in the stalk, I DO get three beeps, but no change in the screen and no EV mode. Any additional thoughts? I have triple checked the connections, etc.

Doesn't the thing have to be working if it beeps?

I get 3 beeps every time I ask for EV and it refuses for some reason,
like temps too high or low, speed or acceleration too high etc.

If the pin wasn't connected what causes a beep of any kind?

But I have the regular Toyota Factory button.

 

This is probably a stupid question but is everyone having this problem sure the battery is charged above three bars before attempting to "force" EV mode? If not you'll get three beeps every time. (I made that mistake after first installing it...) I wouldn't swear to it but the fact that the "switch" is causing any beeps at all means that the connections are intact.

As with the general consensus, good luck getting CoastalEtech doing a professional job at anything. Don't get me wrong, Kelley couldn't be any nicer and their quality control is outstanding from my experience but this product release date for the NAV defeat, the ViewTech 2005 and other products being pushed back month after month after month is absurd, astonishing, bewildering, just plain hard-to-believe... Does anyone else feel like they're in an episode of the Twilight Zone?

 

Believe it or not I DO have something good to say about CoastalEtech. The first EV mode module I installed didn't work either but it didn't even work once. I called them on it and they sent me a replacement at no charge without even asking me to return the defective one. I still don't know if the first one was defective or not. The second attempt works fine but there's a chance "that" pin wasn't fully "engaged". It seemed to seat better/deeper the second time around.

That was months ago though and I doubt if that scenario would be duplicated now that they're working sooooo hard on getting the ViewTech/NAV defeat "to market". (I wish....)

One other thing, they've got great complimentary jelly beans. :wink:

 

When I did the installation on my EV button, I was a little puzzled at first by how the EV mode was entered - some of the documents aren't entirely clear...

You will ONLY get a "beep" going into EV mode if you're not already on the power-monitor screen (that shows the battery status). If you're on any other screen, the display will shift and you'll get the beep. If you're already there - no beep and no other indication that you're in EV mode sucessfully. Seems to be a slightly confusing circumstance from not having the EV mode light on the dashboard.

You will get 3 beeps whenever the car leaves EV mode, either from adverse battery/power conditions, or when you manually toggle it off from any mode.

I've made a habit of toggling my screen to something that's not the battery status display before entering EV mode to make sure I get the beep going in. Just for peace of mind.

Now when I got my EV mode installed, I had a few problems getting into that mode at the beginning as well because it was very hot weather and the battery won't allow EV mode when the battery is hot. After driving around for a while and allowing the cooler cabin air to flow back to the battery, EV engaged easily. No problems at all in cooler weather.

... On a sidenote, I had a regular service checkup today (oil change, tires rotated, brakes checked, etc), and I was curious if they'd say anything about the EV switch I installed, but they didn't seem to care/mind. They did find out that the headlights on my 04 were aimed a bit high, so they angled them down somewhat, but no other difficulties.

Front brakes at about 85% of max, and rear brakes at about 60% - interesting (after about 18 months with the car).

I called Coastal E Tech couple of time to discuss this problem, but only got their silly machine, so here goes...

I've got a 05 Prius with Coastal E - EV Mod and have ongoing problems.

I've double checked all the connections and made sure that all the connecters are properly secured and in particular the HV connector block and still the EV mod does not cause my MFD display to go into ENERGY MODE and it it never has. Any thoughts??? Let me know.

I have to say it took me three attempts to get the pin in far enough. I thought the disassembly of the dash components was the hard part, after all I built a Heath Kit TV in College ( not to mention a Amp, and a pH meter) but getting that pin to seat is a Bxxh. Costal helped me and encouraged me to "keep on keeping on". Make sure the pin is in far enough1

 

Thanks For The Encouragement HdryG!

I perservered and with the aid of you, Coastal and Dr. Evan F. I now understand that I did the install correctly. I just didn't understand the way the system takes over (often when it feels like it) and locks out my CC stalk request.

But now, after 12 hours of learning the tricks and tips, I'm pleased as punch that I can, IF THE SYSTEM ALLOWS, force this car into EV mode and suck them batteries down to 3 bars, then watch the topography, my speed, my "Current" status indicator and SOC bars and gradually coax more power back into the batteries and more mpg out of this little sipper!

Today the EV, tomorrow the EBH!!! (maybe mud flaps too!!!)

Wee, I'm off to see my mpg go +++ up up up.

All the best,

Ken

 

Here's how to know if you are sending the EV signal to the HV or not.
If it doesn't go to the energy screen, but you get three beeps, your mod is working, but the HV is not allowing EV at this time.
If you don't get the beeps or the switch to energy screen, you aren't requesting EV to the HV. Check the pin. Be sure you have raised the pin lock high enough.
Sometime I'll measure what voltage should be reading off the pin if it is in place properly, though I suppose it would be difficult to measure/probe once the plug is in place.

 

What if the MFD display already shows/is in Energy mode and I still can't force it into EV mode (by pulling the CC stalk - and the engine is warm and I'm going less than 34mph, etc.) , does that indicate that somehow the "SYSTEM" won't accept my current request and continues on with its own scenario?

Please advise!

Thanks, Ken
