Removing Coastal Tech EV mod

[tripp]

My Coastal tech mod seems to be going breserk. It randomly comes on and will cycle between on and off every two seconds for long periods of time. It's got to go. I can't find my original documents, but I'm sure it mentions uninstall steps. Does any body have recommendations on what to do? I assume I just leave the taps in place and simply cut the wires between the taps and the coastal tech hardware.

Has anybody experienced such weird behavior with a Coastal tech mod? The thing worked fine for about a year. Then it stopped working at all. Now it can't seem to make it engage with the CC stalk, but it will seem to be sending signals to the car. It seems to happen most often the first time I drive the car each day. Very strange.

Sorry to hear you are having challenges, any chance it is just a loose wire shorting out?
I had posted the pdf instructions a while ago, see link below.
I am sure if you really want to you can work backwards to remove or disconnect the wires.

Mine has been working no issues -

Have you tried getting hold of Coastal? Low likelihood of success, but you never know.

Finally, if you snip the wires on the circuit side of the connectors it should come right off. If you want you can lift the white bar and try to pull the pin that goes into the plug, or just snip the wire and wrap the end with tape so it doesn't short on anything.

You should be able to just cut the wires off. I, too, am thinking an intermittent connection, probably at those clip-on connectors. Coastal Tech might be willing to work with you to fix it. Maybe.

Does your c/c cancel function work okay? If it does, that would eliminate the stalk itself as the problem. It would also mean that the connectors have not actually severed the wire that connects the c/c cancel switch to the plug.

Mine is one of the first production units. I was the first PC member to install it. And I've never had any trouble with it. (I did break the c/c stalk, but Toyota fixed that under warranty.)

Good luck whatever you decide to do.

Thanks lads. I think the loose connection can be ruled out by the precise nature of the beep-beep-beep I hear at speeds over 34 mph (today it lasted a good 20 minutes at a very precise interval... suspiciously it's about every 2 seconds. I will, however, crack the dash open and "have a butchers". Hopefully it is simly a loose connection. If not, I'm gonna snip the wires like you say and wrap the ends with electrical tape. The beeping is annoying, but what's more worrying is that at speeds below 34 mph, the engine cycles everything 4 seconds, with is disturbing and the battery gets more use than it really should. Those are the main thing. I'm not gonna bother with Coastal. They're customer service is generally shite and I can't see them being arsed to help me out. I'll let you know how it goes. Daniel, good idea testing the CC stalk. I will try that out tomorrow on my way to work and see if there ary issues there.

CC stalk seems to work fine for its normal function. It doesn't, however, engage EV mode. Since the stalk works for canceling CC the problem must be in the chip or the connection.
