Disable RAP After Remote Start Relay?

hey howie,

I have a python 574, do u know if this dei alarm has a way to pulse a door trigger after remote start end to turn off my radio, without setting off the alarm if armed, by thinking the door opened without disarming?

Have't a clue but I can't see how.

Difficult because you haven't given us car, make and model, is this Spoon Feeding or what?

Obtain a standard 5 pin Bosch/Tycho relay. Take a feed from your ACC supplying the radio and cut it.
Supply side to 87a.
Radio side to 30.
Feed from R/S ignition 2 to 86.
Ground to 85.
Diode, 1N4004 in line from Ign 2 to relay 86, band towards relay.
Can't be responsible because as I said before, if you're too lazy or dumb to give us your vehicle details....

My post was incorrect, ground relay (85) via R/S "status output" or GWR wire.
If this is connected to other items such as a by-pass then diode in line to relay 1N4004, band towards R/S.
86 to a constant 12v+ live.

thanks howie,

my bad it is a 2008 ford escape.

I did a little more searching before your reply and I found this, possibly an easier solution?

https://kb.directed.com/knowledgebasearticle11730.aspx

From what it seems I could just connect the H2/24 (GREEN / WHITE) OEM Arm Output on my remote starter and connect it to the BCM Connector C2280C in my escape on Pin 14 (Switch - Latch Driver Door Ajar - GREEN/ Violet) and since that wire is automatically pulse on the remote starter at the end of the remote start session it would shut the radio off because the vehicle will think the door was opened and then closed again.

I was also considering this route because I have to mess with the door triggers to install a DTIMAZDA Door Trigger interface anyways for my alarm, so it is not using the dome light for a door trigger.

Thoughts?

Won't work because the R/S is STILL feeding the ACC wire.

even at the end of the remote start when it is disengaged? I don't mind if the radio is on while the car is running, I just don't want it left on after the remote start shuts off.   Your relay diagram if i am correct would not have the radio on at all if the remote start is on, correct?

- Dan

Yes and the RAP switches off with the R/S if you don't get into the car to drive away so your original post is pointless.

yea door trigger option is out... ford and mazda door triggers rest at ground, and go open when the door is open. So there is no way to pulse a door trigger that is already resting at 12 volts. the 12 volts would actually have to be cut for a second when the remote start ends and then put back again so the car thinks the door was closed again. I suppose this could be done with a relay setup as well or just do it your way. which is prob what will happen.

So make sure i have this right.

Pin 85: GWR
Pin 86: 12+ Constant
Pin 87A: ACC to Radio
Pin 30: ACC from Radio

Don't use ign 2 as you originally corrected in your post on pin 86, correct?

Hey guys,

Need some relay assistance.

I have a 2008 ford escape and I need help keeping my radio off during and after remote start (if I don't get in the car for some reason, RAP keeps it on for 10 mins)

With some assistance, I set this up to disable the radio while the car is running on the remote starter.

PIN 85: Ground While Running of Remote Start
PIN 86: 12+ Constant
PIN 87A: ACC to Radio (Radio Side)
PIN 30: ACC to Radio (Car side of to radio)

This works great, except if I don't get in the car before the remote start ends, the radio turns right on after the car shuts off.

Now here is the tricky part, I cannot pulse a door trigger with the OEM Arm output because my Ford door triggers rest at ground and go open when a door is open. I can't negative ground pulse something, that is already negative grounded, nothing is gonna happen.

Door triggers already have a DTIMAZDA interface for the door trigger on the alarm).

I need a relay setup that does something like this:

1. Uses OEM Alarm Arm (-) output on remote starter that pulses at remote start end
2. Breaks connection to a grounded door trigger when the car shuts off and makes it open when the OEM Alarm Arm wire is pulsed.


I had this in mind, would it work?

PIN 85: OEM Alarm Arm (-) Pulse
PIN 86: 12+ Constant
PIN 87A:(-) Drivers Door Trigger (Door Side)
PIN 30: (-) Drivers Door Trigger (Car BCM Side)

Basically the door trigger wire is always connected and the car always sees the grounded trigger wire. However at when the remote start shuts off, the connection is temp broken on a ground pulse as it switches from 87A to 87 then quickly back again after the pulse is done.

Am I on the right track?

Wire from Remote Start: H2/24 (GREEN / WHITE) OEM Arm Output
Description: This wire sends a negative pulse every time the remote start shuts down or the doors are locked. Use a relay to send a (-) or (+) pulse to the arm wire.

Door Trigger: BCM Connector C2280C Pin 14 (Switch - Latch Driver Door Ajar - GREEN/ Violet)

hi,
the relay should work, make sure its on the BCM side of the DTIMAZDA.
otherwise the alarm will be triggered.

Thanks,

Do you think I should put a diode across the 85 & 86 terminals for back emf and is it necessary?

Or you can simply turn off the RAP via the R/S programming.

my python 574 has no option in its programming menu to disable rap. even on the knowledge base website i posted they say to pulse a door trigger wire, this relay is the only way for me to do it.

OK, just checked the installation guide, interesting you could turn it off on older models.
What I still don't understand is why you would want to run the remote start on its full duration and then and then not get into the vehicle and drive away. At that point RAP is moot.
DTIMazda not needed, look here Downloads/Manuals for an alternative method.

i already installed a DTIMAZDA for my door triggers, so that part is all set.   Basically say I remote start while I am at work when I am about to leave, and I get stuck helping a customer and I actually don't get to leave on time and my car was left running, my radio stays on. Or if I am at home, and I start doing something and loose track of time when I'm getting ready to leave, I don't want my radio killing my battery.   Basically as simple as that, normally it won't be an issue but 1 out of 10, it is.

OK last question then. Do you actually know that when the R/S has finished the RAP comes on? Also unless you have an amped system, 10 minutes won't make any difference to your car battery.
If you have already installed a DTIMazda then I suggest you run with my amended relay set-up since the other method might be a pain to interface with the DTIMazda.

Yes, I installed your relay which keeps the radio off while the car is remote started, but once the remote start turns off and the GWR wire no longer has a ground, 87A switches back to 87 and turns the radio on lol. Yes I have an expensive Kicker system in my truck and it will kill the crap out my battery if left on to long. I do have a Optima Yellow Top however, so it can take a beating but that's besides the point.

I think I am going to cut the drivers door wire on the BCM side of the DTIMAZDA and put that relay setup I wrote there and see how it works.   So Basically it is already cut.

--Drivers Door Trigger IN ---> DTIMAZDA (BLUE WIRE)----> Door Trigger OUT ---> MY Posted Relay Setup ----> BCM IN --

What do you think? Should I diode across 85 + 86 on that relay?

- Dan

Should have said 87 switches back to 87A and turns the radio on, not the other way around.

- Dan

OK, you've answered all my points correctly and intelligently So I apologise for being condescending or patronising
You caught me in a mood because my (English) soccer team(Spurs) only drew yesterday when we had a chance of catching the leaders but I'm now in a better mood because our deadly rivals (Arsenal) are loosing as I write.
Yes to the diode, 1n4004 across the coil, band to pos. side.
