remote start 2006 honda pilot

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.Gary Sather

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?mattb

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.mattb

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!!mattb

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.mattb

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