Coastal EV mode died

[psibill]

Looking for help in diagnosing this problem.

Have 2006 prius. Installed the Coastal EV mode mode. Worked fine. Now, it doesn't work. Pulling the cruise level toward me and holding for 2 secs or so, nothing. If the ICE is running (after warmup) and cruising below 34mph, ICE won't shut down. If trying to go into EV mode while the ICE is in warmup mode (yes, I know it won't go), I no longer get the warning on the MFD that "can't enter EV mode now."

So, something definitely up. It IS curious that, although I don't drive it that often, the problem seems to have occurred after the car's first service period at the dealer. Any chance they could have somehow disabled the programming?

If I wanted to test the EV mode programming to see if it's still working, can I just short one of those wires to ground? Which one?

Thanks.

Bill,
First I would check your connections again. In particular, check to see if the pin you inserted into the wiring harness is seated properly. If that doesn't work call or email coastal. Warning, be patient and persistent with trying to get a hold of Coastal. Good Luck!!

Have you eye-balled your connections? In particular your tap to ground and the pin in #27 on the ECU...those can pretty easily come lose. Of course you've got another tap with the Coastal rig so check that as well.

The programming hasn't, I'm absolutely confident, been changed. It's highly unlikely the dealership has any clue that the mod is there. If they do know there's something there they probably don't know what it is. There's been no TSB issued about disabling any EV mods.

But, if you've got to test you just need a momentary ground to pin 27 to test.

Has it been brutally cold where you are? I've noticed a possible connection between temp and the thing not working. It's been warmer here lately and it's been working fine again.

[psibill]

Yeah, but I'd not expect a bad wire connection. It can happen, of course, but...

I did just visit, or tried to visit, their website.

I got a "service unavailable" page. Hope that doesn't mean anything bad.

do you have their phone number, in case the website doesn't come up for a while?

Thx.

That depends on your reference. Yes, we had a few days of really cold whether a week or so ago. Got down to the low thirties. But it's much warmer now.

The EV mod looks like it's working fine if you go the message that said it can't go into EV mode. There's just some other factors that prevent the Prius from entering EV mode. Temperatures, SOC, etc... could be preventing EV.

But he did say "I no longer get the warning on the MFD that 'can't enter EV mode now.'"

It sounds like a connection came loose to me... I would try shorting that pin on the computer to a ground source.

oops.. missed that "no longer" part.
