Need help with Remote start - disarm/rearm factory alarm
 

Car: 2001 Accord EX. I'm trying to install an alarm with remote start. It's a Viper 5900, but this applies to Clifford Matrix 50.5X, Python 990, Clarion Ungo SR9000, and many other DEI (Directed Electronics) alarms with remote start. They all have identical wiring schematics. (DEI's customer service sucks for individuals by the way :mad: )

My question is: How do I disarm the factory alarm without unlocking the door locks? This is desired during remote-start.

I know that the EX models arm and disarm with the door locks, and LX only arm with transmitter. Luckily I have an EX. On DEI remote start alarms H2/4 and H2/6 are for rearming and disarming the factory alarm. These are not required if I can arm and disarm the factory alarm simply by letting it use the lock and unlock outputs of the DEI alarm. But, when I use remote-start, I need to disarm it without unlocking the door locks. I guess that is where H2/4 and H2/6 come in, but how can I wire them so that the factory alarm can disarm without unlocking the doors?

note: I'm also using a universal 556u immobilizer bypass, but that doesn't really have anything to do with this. It only bypasses the key's immobilizer so the car starts without a key in the ignition.

it is not possible by not disarming the alarm without unlocking. Try it first without unlocking. i did a 98 accord DX and without using factory disarm wires or unlock befor start, it worked fine. Also, why are you worried about the unlock-start-lock, its a process under 10 seconds. you do have the brake shut down wire... In programming program so it will pulse befor start. wire the factory arm and disarm wires with the lock and unlock. so to simplify, FAC ARM with LOCK and FAC DISARM to UNLOCK. Diode isolate both wires with the cathode band towards alarm unit.

Guess you're right. If it is only unlocked during cranking, then it doesn't matter. I haven't installed it yet, so I don't know how it'll all work out. And, then there is probably no point to the FAC arm and FAC disarm for this vehicle if it's already take care of by the locks. But now I know how to wire them if I wanted to.
I think I would have passed up using the diodes and killed it, if you didn't tell me. I'll definitely make sure I'll use diodes where needed. Thanks ;)

Question: you said to program so it will pulse before start. Are you talking about the

yes taht is correct. Use the function REMOTE START ONLY. and grab 4 diodes. 1N4004 or any 1 amp diode will be fine. Just connect your factory arm together with your locks and factory disarm with your unlock. Place a diode on each line with the white band (cathode) towards the alarm unit.

Great. got it; program REMOTE START ONLY and use 1 amp diodes [1N4004]. Thanks so much for the help.

Here is something cool: I stumbled across the XK02 - Immobilizer Bypass and Door Lock Control (more info at http://www.bypasskit.com/product.aspx?prodid=XK02). It looks like it saves some work by communicating to the Factory alarm through a single data cable. It also gives the programming option for: 1st Pulse Unlock Driver Door, 2nd Pulse Unlock All Doors. Just like the factory alarm. Maybe the DEI alarm can already do that without this unit... I don't know?

I already have the 556u, but I don't like that there's a key in the car for someone to steal... and then steel the car. I don't want to use my only extra key, so I need to go get another from the dealer ($25), but I found the XK02 for $46 [buy.com], so I might just go for it. I know there are other good keyless immobilizer bypass modules which can be found on eBay for $20-$25, but this one is integrated with the factory alarm through a simple data cable, which takes care of the door locks - That is nice

EDIT: Sorry, I made a mistake: The XK02 DOES NOT act as an immobilizer bypass. Only as a door lock control module

the 556hw(?) is the honda version that doesnt require a key in the car.

556HU?

its actaully 555hw. You can pick up IMO the best bypass kit i have used which is the Fortin HONDA-SL3. Dont bother going with data kits because 1) you are simply wasting money and 2) that kit doesnt even work with your car. Its nice to use DATABUS systesm on NEWER cars over 2004. Since yours is a 2001, a RS/alarm and data will not work and it just cost more money. Just hardwire everything to the specified wires from the remote start to the proper wires on the vehicle and you should be good. Go with fortin, its cheaper but quality is amazing. the kit by bypasskits.com for honda is the
PKH34 which is a PITA to use. btw these are ALL DATA BYPASS so no keys required. Just one master to program.

the best bypass kit i ONLY use are
Fortin Electronics (www.ifar.ca)
iDataLink ADS-TBSL-HA which is honda specific (www.idatalink.com)

Thanks for the advice Tedmond, but I don't think you are talking about the same thing. It is not using DATABUS. It is using a "data" wire. At bypasskits there are two products for my car (2001 Accord) which use a "data" wire that communicates with the factory alarm.

They are the XK02 and the HODL. You can check out there manuals to see what I'm talking about.

Compatibility Charts
HODL - http://www.bypasskit.com/chart/HODL.htm
XK02 - http://www.bypasskit.com/chart/XK02.htm

Both compatibility charts specifically say these functions work for my car:
# DL- Door Lock Control
# DL- Door Unlock ALL doors
# DL- Arm factory security
# DL- Disarm Factory Security
# DL- Trunk / Hatch Release
(this is all done through the "data" lead)

Unfortunately the HODL is only meant for that, and does not act as an immobilizer bypass. I would need another bypass unit to make this work.

The XK02 is a DEI product made by XpressKit (xpresskit.com). Their website has the same compatibility chart as the one at bypasskit.com (above)

The ADS-TBSL-HA only does the door lock functions for 03 and up (like you said)
None of the Fortin kits I could find will control door locks for my car.
Also, the PKH43 does not fit my car (it's the PKH2)

So I have three options: (1) the XK02, (2) the HODL with an immob. bypass unit, or (3) wire everything myself and use any bypass kit that will do the job.

I'll probably go with the XK02 (or the HODL + another bypass if it is cheaper)

EDIT: Sorry, I made a mistake: The XK02 DOES NOT act as an immobilizer bypass. Only as a door lock control module

I don't know if the 556HW (not 556HU) is still made. You can still by it everywhere, but it is no longer on the manufacturer's website.

I found out that the PKH2 and HODL are sold to many different companies (including BypassKit.com) who stamp their names on it for resale. I think the company who develops it is Omega Research & Development - Not positive though.

sorry for not makin it clearer. i was actaully refering to DATA bypass so no keys required, not DATABUS interface; but the company idatalink, they dont offer much for your car. If you wanted to get a bypass that controls all of the following as you mentioned
# DL- Door Lock Control
# DL- Door Unlock ALL doors
# DL- Arm factory security
# DL- Disarm Factory Security
# DL- Trunk / Hatch Release
(this is all done through the "data" lead)

the HODL is the ONLY one taht will do those for you. the XK02 Does NOT offer car status through canbus wires. I would either suggest you go with the HODL bypass or wire everything else up with a Fortin Honda-SL3. The 2001 accord is actaully very easy to do. No need for the expensive canbus data system. All wires are in drivers kick/fusebox and some wires are in the passenger fusebox.

I'm unsure why you are saying that the XK02 won't perform those functions??? If you take another look at the XK02 compatibility chart (http://www.bypasskit.com/chart/XK02.htm), and hover the mouse over a 2001 Accord, it will show that those functions do work my car. If you look at the installation manuals for each...... you will see that they both have the exact same wiring harness. Only difference is the XK02 has an additional (optional) D2D connector to simplify wiring to the aftermarket alarm.

In the description of the XK02 manual, it says:
WIRE COLOR: Violet
I/O STATUS : Data
FUNCTIONALITY: Lock/Unlock/Arm/Disarm Via Vehicle Data Wire

So there you go. The XK02 DOES perform those functions for a 2001 Accord. The compatibility chart says it does, and the Installation manual shows how it does. If it does not, I can return it because it would be defective according to the manufacturer.

Still not sure why you agree the HODL does but the XK02 doesn't???

I just realized that the XK02 does not act as an immobilizer bypass, like I previously stated. It ONLY controls Door Lock & Arm/Disarm functions (Just like the HODL).

It is definitely not worth more than $10.

Sorry for the mistake.

if you look @ the compatability chart, the cars in YELLOW are the cars that the unit works with. if you look under 2001 accord, your car isnt YELLOW . its greyed out because that doesnt work. Even if you hover your cursor over, it shows the same info for all cars since that is what the unit is capable of doing.

grey doesnt mean that it doesnt work... just means that not everything will work.



im going to email or call them and see what help they can offer.

purchasing the kits is kinda waste of money. All wires are easily accessable in DKP and PKP. no wires are needed in the door. Save the money and just buy a simple bypass kit.

Not true. It does not show the same for all cars.Compatibility Chart for XK02: http://www.bypasskit.com/chart/XK02.htm

I agree that is a kinda a waste of money. It's not a bypass kit; only a door controller, which can be done by the alarm without the unit.

are you using the D2D wiring connection from the DEI? im sure DEi hasnt added this to their units yet. They have datalink connection (4 wires) but no D2D yet. Only audiovox has thid and still didnt prefect it. major bugs. I suggest you jgojohn to just wire everything without the purchase of any modules. Just pick up the Fortin Bypass (HONDA-SL3, or SL2 which is discontinued but some places still go them) its about 30 CAD so prolly cheaper in the states.

I would use W2W (wire to wire). I don't have anything else that has a D2D (data 2 data) port. Seems like D2D is the same thing. For other cars, it allows all the features, but their not available for my car anyway. It also makes wiring more simple, and you can flash/upgrade the firmware.

Another reason the XK02 is a bad deal (and any other Xpresskit modules: XK01,XK03,XK04XK05...) is you may need to program it. To program it, you need to buy the USB programmer adapter to connect it to the computer. It is called the XKLoader, and it is $60 (cheapest). The XK02 for example comes with Nissan firmware preloaded, so I would need to flash it with the Honda firmware. That means I would need to spend an extra $60 to do that. What a retarded product.

I ended up buying the PKH2 (generic brand, which doesn't matter since they are made by the same manufacturer). It was $15 shipped.

I would have bought the Fortin HONDA-SL3, but I could not find it for less than $30 plus shipping.

I'm going to have to wire the door locks and such without a factory OEM controller.

if you need any diagrams let me know. the think with XK, you can ask them to flash it then shot. but the PKH2 will do fine. the PKH2 is manufactured by one company, sold to others for them to brand as their own.

That's cool. I have the diagrams, thanks
