remote start 2006 honda pilot

I installed a Viper 5701 on my wife's 2006 Honda Pilot. Everything worked fantastic except for the dome light issue that everyone seemed to have. I saw on the forum that hooking up ground when armed to negative key sense wire solved the problem. I did this and the dome light problem it solved, but now the vehicle will not crank with the key, only the remote start. Please Help!! I used the orange wire of the 5701 to the blue/black negative key sense wire at key cylinder.

The ground while running wire should be hooked to the key sense not the ground while armed. The ground while running or status output wire should be a small blue wire with white stripe. I've never seen that cause a no start issue before though. But hook the correct wire to the key sense wire and see if that solves your issue.

I will try that. Thanks a ton!! I will repost with the result.

There is no dome light issue with any Honda or Toyota after 2000 also post 92 BMW these vehicles have dome light supervision built in therefore use the dome light switched ground as your door trigger.

Actually does sound like power at switch. Usually Honda failure is in the engine bay fusebox, fuse is either marked BATT or IGN.

Ok, so I changed the wire from ground when armed to ground when running and the vehicle tries to crank, but the vehicles transponder bypass will not allow it. (key flashing on instrument cluster).   On the other hand it remote starts like a dream. I'm using a 556u immobilizer bypass. So why does grounding the key sense wire with negative status output (blue/white from remote start to blue/black at key cylinder on pilot) inhibit my key from overriding the transponder. If I can figure this out all my problems will be solved.

Also, I can disconnect key sense wire and the key starts the vehicle with no problems, so I know for a fact it has something to do with the vehicles (-) key sense wire being energized.

The ground while running from the Viper does not have any ground through it when the vehicle is not remote started. Or at least it shouldn't. Test the wire to make sure there is no ground feeding down the status output or ground while running wire when the vehicle is not remote started. If there is ground going down that wire when the vehicle is not remote started you can use a relay to isolate it.   I highly doubt that is the problem though and less there's a problem with your Viper system. The alternative would be to look at how your 556u is wired. The 556 you should also only see ground while running not ground well armed. Meaning the same blue wire with the white stripes to be hooked up to the key sense as well as the 556. If the 556 inseam ground well armed etc. then basically when you go to start your vehicle with the key it is seeing two keys at one time and confusing the immobilizer system.

I also apologize for my grammar Siri seems to have a mind of her own. LOL

If the OP is using that same blue/white for both they should be diode isolated otherwise dark blue for one and blue/white for the other.

Yes

It definitely sounds to me tho that the immobilized is seeing two keys at one time. Definitely a 556 wiring issue. The 556 should only be on during remote start.

X 2 with Gary.
Or use a DB-ALL2 and remove the key from the equation.

I'm sorry, what is OP? As far as the diode goes would that be placed in line of wire going to vehicle key sense wire keeping ground from being fed back into 556u from key sense wire?

Also I tried connecting the solid blue wire from remote start brain to key sense wire with same result. I am not using blue/white for both key sense wire and status output to 556u. Thanks again for all halls help. I know a 556 u is old school but that's what I am. No one around me I trust to flash the new fancy bypasses. I know they are much easier. I'm tempted to wire a relay to break connection between key sense wire and (-) status output when ignition is turned on with the key.

You are the OP = Original Poster!
I take it you are using dark blue for 556 and blue/white for key sense, or vice versa. In that case the diodes aren't required.
As a pro, the DB-ALL and it's equivalents are great time savers with minimal wiring, = less chance for errors to creep in.

Ok guys I have seen the light, haha. Somehow in the mess of trying to fix this issue I had disconnected my green key sense wire of the 556u from the vehicle's key sense wire at the key cylinder. Once I reconnected this wire my issue flip flopped. The key would start the vehicle but the remote start would not due to the vehicles transponder system seeing two keys. So, when all is said and done I will have essentially two wires coming from vehicle key sense wire. One going to the (-) status output of the remote start (blue/white) while the other going to the green (-)key sense wire of the 556u. Now, if one of you geniuses can refresh my memory on how to diode isolate these two from each other, I believe I will finally have this thing whipped! Did I mention you guys ROCK!? Oh and p.s. I don't care how bad Siri's grammar is as long as you help me, lol!!

Two 1N4004 diodes, one on each line bands towards Viper.

I just saw the post about using solid blue (-)status output of remote start to 556u blue wire and taking blue/white to vehicle key sense wire. If I do this should I still leave my green keysense wire hooked up to the Honda Pilot keysense wire? If I can do this and avoid diodes that would be great, just not sure what to do with the keysense wire from 556u, if anything.

I always used both stud wires from the Viper, one to the 556U and one to the key sense, no diodes, no green required.

If you use the blue and blue white wires you won't need to use diodes and won't need the green from the 556

Ok, I'm gonna try the two status output wire method without diodes first thing in the morning. Ill post the results.

Using both status output wires worked perfectly! Thanks for all your help guys. My wife thinks I'm a genius now, haha!!
