04 f150 with viper 5906v will not turn off

I have installed a viper 5906v remote start on a 04 f150 with idatalink alca interface. it is supposed to turn off when you step on the brakes. but my truck will not shut off it says "remote start deactivated" when i step on brakes and it will not even allow me to turn it off with a key. the only wire i cannot figure out is the 24pin connector dark blue (-)200mA status output. where would this connect or what have i done wrong for it to not turn off? Thank you.

It would help if you listed the connections you made from the viper to the truck.

Is the 24 pin WHITE/ blue connected to anything?
That or your pink ignition on the Viper might be to a constant?

The 24 pin WHITE/ blue is not connected to anything. also the 10 pin pink is connected to db/lg on the ignition harness.
i followed the instructions from another write up on this forum.

Wiring:
24 pin harness:
(Pin 4 BLACK / YELLOW) (200ma dome light) I did not hook this up, the dome light comes on as soon as you disarm do to the locks unlocking.
(Pin 5 Dark Blue) (200ma status out) idatalink has data mode so does not need to be connected.
(Pin 13 BLACK/ White) (Neutral safety input) Connected to ground.
(Pin 15 Green) (Door trigger in) Connected this to the BLACK / YELLOW and the BLACK/ Pink on the BCM, using diodes. I did not connect to the rear doors because I have a crew cab and the front doors have to open before the rear doors, if you have a super crew cab with separate rear doors you will need to hook those wires up as well. I used the diode wiring diagram from Bulldog Security https://www.bulldogsecurity.com/diagr...0ISOLATION.pdf
(Pin 16 BROWN / Black) BCM dk/blue plug
( pin 20 Brown) (brake Shutdown input) connected to green on brake.


10 Pin harness:
(Pin 2 RED / Black) hooked this to the GREEN/ YELLOW on the BCM.
(Pin 5 Red) (30 Amp fused 12V ign 1 in) hooked this to the GREEN/ YELLOW on the BCM.
(Pin 6 Green) (Starter in key side of starter kill)Connected this to the RED / Light Blue wire on the ignition harness.
(Pin 7 Violet) (Starter out car side of starter kill) Connected this to the RED / Light Blue wire on the ignition harness.
(Pin 8 Orange) (Accessory out) Connected to the BLACK/ Light Green on the ignition harness.
(Pin 10 Pink) (Ign 1 in/out) Connected to the Dark Blue/Light Green on the ignition harness.

Door Lock Harness:
(Pin 1 Blue) (500ma unlock output) Connected to Pink/Light Green on the BCM.
(Pin 3 Green) (500ma lock output) Connected to Pink / YELLOW on the BCM.

Main Harness:
(Pin 1 Red) (Constant 12V Positive) hooked this to the TN/WH on the BCM.
(Pin 2 Black) (Constant 12V Negative) hooked this to the BK on the BCM.
(Pin 3 Brown) (Siren out) Connected this to the sirens red wire and connected the sirens black wire to a ground under the hood.
(Pin 5 White) (Parking light out) Connected this to the brown wire on the BCM.

Have you tried to apply 12 volts (+) to the Brake Shutdown wire independent of the brake switch wire to see if it will shut down?

Otherwise the wire connection look good to me.

Yes i did try to connect a 12v constant to brake to see if it would shut down but it did same thing "Remote start deactivated" but still keeps running.

sounds like the unit is defective. only thing i can think of. Did you check the continuity of that wire up to the connector, might be broken

Yes check that brown wire from brake at the 24 pin plug, see if you have 12 volts AT THE PLUG when you press footbrake with ignition on.

He says the fob indicates "remote start deactivated" so it is receiving the brake input. It seems the unit is not shutting off the power on the pink IGN output.

Try a remote start. But IMMEDIATELY push the brake as soon as you see the dash lights come on. Does it shut down? (dash lights go off).

I'm curious how the datalink is wired. You said you didn't use the dk blu Status Output. So what did you connect the bypass GWR input to? The blu/wht on the idatalink should go to the blu Status Output on the Viper.

Do any of the other shutdowns work? Like the hood? Or Neutral Safety (disconnect while running, it should shut down)?

OK i double checked and yes there is 12volts at the brown wire when i press on the brakes.

also Davep. I tried pressing the brakes as soon as the lights come on and it would not crank. it says "brakes on". and i tried pressing brakes immediately after crank and it shut off the truck. but after maybe about 15 seconds i hear a click on the module and after that i am unable to shut off the truck either by pressing the brake or neutral safety switch or the hood open. both the neutral safety and hood switch operate cause it would not turn on if they were engaged. and as per idatalink module installation instructions it says if you are using the device on data mode no other connection is needed to the remote start module since it has all the connections on the D2D port. but i will try connecting the blue output wire tomorrow and see and post the results. Thanks again guys.

I don't have any experience with the idatalink, so I'm flying by the seat of my pants, and following the install guide. I do see in the install instructions they show a connection for the GWA, but also a legend that "not required in data mode 2-way". What ever that means. I'd hook it up. It may help, may not. Can't hurt to try.

The other thing is the "click" after 15 seconds. This is the main clue. If I'm following correctly, it shuts down with brake, hood, and neutral BEFORE you hear the "click". Figure out where the click is coming from. The idata, the Viper, or something in the truck. (Most of the relays in the truck are in the junction box in the passenger kick. But there are a few in the instrument panel).

The only thing that I can think of that changes in the Viper after 15 seconds is it turns on the Rear Defroster, if programmed. But this output is solid state, so it doesn't "click" internally. But an external relay could.

BTW, how DO you shut it off if the brake doesn't do it, and neither does the key? Use the fob?

ok the i hooked up the blue wire and did hardwire mode on idatalink still the same result. i have to unplug the power to viper for the truck to turn off. also the click sound is coming from the viper system.

This is a good question.

Also, You don't happen to have any external relays wired, do you?

I'd be trying to measure some voltages. Remote start the truck. Check your voltage on the pink and orange wires in the main power harness. They should both be +12V when it's running. Push the brake and check the voltages again. Are either of them at 0V?

If the pink wire stays at 12V, but the orange wire drops to 0V when the brake is pressed, I'd see if the second ignition output (pink white stripe) acts any differently.
