2007 hummer h2 viper 5704

Hi everyone,

I'm a rookie  when it comes to 12 volt, but atleast I'm trying. Anyways I have a Viper 5704 w/ 5904( 2way) remote and Idatalink ADS AL CA. Vehicle is a 2007 Hummer H2.

I'm looking for any help pics, comments, tips, suggestions to verify I have done the intall correctly.

So far what I have accomplished, the alarm and basic wiing is hooked up. I am able to get a solid led from the control antanne, but thats all. When I try and get it in to program mode the siren will not chirp nor will the control antanne led flash.

When I hold down the arm button on the remote (1 way ) the siren chirps however the doors do not lock. Also when I hold down the disarm button on the one way remote the siren does not chirp and the doors also do not unlock.

Once again any help would be greatly appreciated.

Thanks

Did you flash the correct firmware on the ADS-AL for your vehicle? Did you follow the programming steps once installed in the Hummer?

There is also a lot of info on this vehicle in the forum if you search it.

The viper manual will tell you why you have a solid LED on the antenna.

Thanks for the quick reply,
No i didnt flash the ads al. Ill try and get that done and post a update as soon as possible.

Just ordered the weblink will bew a few weeks before it shows up. Ill update as I go along.

Its gonna be a couple of weeks before I can get the module flashed so I decided to do some homework.

I found this on another thread and was wondering if it applied

Try this:

get connected to anything?

the more i read the more i question my install, going to remove and redo everything for a more cleaner install and plan on taking pics to upload.

A few thoughts / updates...

Besides the ADS USB cable, you must register on the Flash section of the iDatalink WEB site and
pass their requirements to be able to use the ADS USB cable and re-program any bypass module.
Additionally you can flash the ADS or the DBI flavor of firmware on to the module.  With the
ADS version, you must connect the bypass to the Viper in W2W mode.  With the DBI version you
could go D2D.  ( I don't use too many Viper systems so I can comment on how well DBI D2D works.)
The correct firmware for your ADS AL CA is ADS AL(DL) GM1 using install guide #6611 and the
Type 3 install diagram.  If you decide to use DBI firmware and go D2D, the correct firmware
is DBI AL(DL) GM1. Here is a link to the iDatalink WEB site :  https://www.idatalink.com/support

Here is Viper's info on H1/6 GWA :
This wire supplies a (-)500 mA ground as long as the system is armed. This output
ceases as soon as the system is disarmed. The GWA can be hooked up to a
window control module, a voice module or any accessory that requires a ground
when armed.

It can also be used with programming option 3-13 to provide the Anti-Grind feature.  Viper info below :
3-13 ANTI-GRIND ON: With the anti-grind On (default) the ground-when-armed
output will be active during remote start operation. This activates the starter
kill relay and prevents the customer from re-cranking the car with the key, when
doing key takeover. If accessories such as a voice module or window module are
added to the unit, it may be necessary to use the two-chirp setting to program
this feature OFF.

Re - re-doing install :
This is a fairly easy install with the ADS bypass module.  It does most everything for you.  I would mate the Viper to the
properly flashed ADS AL CA bypass module in W2W mode on the bench, prior to vehicle install.  Solder all connections
and use heat shrink tube where ever possible.  The only gotcha is the rear door pins.  To do it correctly you will
need some diodes ( 1N400x ).  Here is the info from Ready Remote :

The driver door trigger is gray/black (-) at the driver door module in the door. The RF door trigger is BLACK/ white (-)
at the passenger door module in the door. The LR door trigger is lt. blue/black (-), pin A3, and the RR is lt. GREEN/ black (-),
pin A2, they are in the purple plug at the BCM. Use all four wires and diode isolate each.

The BCM (Body Control Module) is located behind the headlight switch. It has 6 plugs in it, the purple plug is on the back.

The ADS bypass module supplies the front door triggers as previously mentioned.  You will need to diode isolate the two
rear door status wires from the truck and join them into the Vipers H2/6 Green (-) Door Trigger input which already has
the ADS (-) Door Status Output.

As always, use your DMM to locate and verify all vehicle wires ( except OBD2 Data ).

Sorry but I'm confused on where I can hook up the GWA.

On a basic installation, the H1/6 GWA wire is not used.

If you feel you must use it, the easiest, least time consuming and inexpensive way is to connect it to a DEI 629L light ( or similar scanning LED light assy ).

Can ifet mire details about the relay installed for the brown acc wire. Why are only three pins used and two of them are 12 v constant ?

* can i get more details

Actually 4 relay pins have connections.  Here are the relay operation details :
Under normal conditions, the un-energized relay will have a connection between pins 30 and
87A ( marked N.C. for normally closed ).  Relay Pins 85 and 86 are used to energize the relays
coil.  Standard convention has Pin 85 being (-) and Pin 86 being (+).  To energize this relay,
we connect Pin 86 to a constant +12V and Pin 85 to the Vipers (-) Accessory control signal.  So
when the Viper outputs the (-) Accessory signal the relay will energize and switch to the N.O.
wire ( normally open ), making a connection from Pin 30 to Pin 87, and opening the connection
between Pin 30 and 87A. 
So, with no Viper (-) Accessory output, the relay is internally connected Pin 30 to 87A and
supplies nothing out Pin 30 to the vehicles Brown Accessory2 wire.  When the Viper outputs
the (-) Accessory signal, the relays coil energizes and internally the Pin 30 contact switches
from Pin 87a to Pin 87.  Pin 87 is connected to +12V constant power and allows relay Pin 30
to supply the vehicles Brown ACC2 wire with power.

Brown ACC2 wire at ignition switch harness requires extra 30/40A SPDT relay :
Pin 85 to Viper H2/22 Orange (-)200mA Accessory2 Output
Pin 86 and 87 to +12V Constant thru 20A fuse
Pin 30 to Brown ACC2 @ Ignition Switch Harness
Pin 87A not used - insulate

The 12Volt has a very good write-up / explanation on  relays too.  Here is the link :  https://www.the12volt.com/relays/relays.asp

Which of the inputs on the idatalink are not used ?

*in w2w mode

Here is a link to the ADS AL CA flashed with ADS AL(DL) GM1 firmware install guide :
https://www.idatalink.com/support/get-install-guide/guide_id/6614    This is the correct
firmware for your 2007 H2 when using the ADS AL CA module.

Follow the Type 3 install diagram for you 2007 H2.  You will run all the wires shown with
the exception of the Trunk Release, Left and Right Sliding Door wires.  They are not
applicable to your vehicle.  Additionally the ADS Door Status Output will only supply
the front doors.  To monitor the rear doors see the info previously supplied.

I've decided to go with the d2d setup.
Everything is hookep up. I'm having difficulties programong the viper alarm, idatalink and pairing the 2way remote. 1 way appears to be paired. When i arm and disarm from the 1 way i get a chirp and led on control center flashes consistently. I am unable to put the viper into pairing mode for tge two way. No matter which way i try it wont flash or chirp to say the system is ready for pairing.

I have the right firmware DBI-AL(DL)-GM1(v4.4)

*v4.8

also the idatalink flashes green and when I turn the car over it doesnt flash until the car has finished cracking and started. When I push the remote start button on the one way I can hear the relay clicking but no action otherwise.

doubled checked all connections, everything looks good. First I'm working on how to pair the remote. I can't seem to get the control center to engage pairing mode. Tried power cycling which didn't change anything.

Even with the idatalink not hookedup I should still be able to pair the remote with the viper unit?

also let me add that I can still start the truck with the key, with out any problems

Tip. Temporarily ground the green H2/6 wire.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Grounding the h2/6 has lead to some success. I was able to get tge alarm to engage in the programming mode.

That means your door trigger at present isn't connected.

But still unable to program the 2 way

Is the 2 way charged?
Is the battery solidly in?
Do you have to program it to the R/S?

Yes 2 way fully charged, yes battery in, yes i need to program it to remote start and fully functional alarm.

You should be able to pair the remotes regardless of having a bypass module connected to it or not.

Make sure that door trigger wire is grounded prior to turning the ignition switch on.
Turn the ignition switch on and keep it on before attempting to pair any remotes (unlike programming features where you would turn the key on, then off). Then go thru the pairing process and keep fingers crossed.

Did the 2-way remote come with that system? Or did you buy it separately to add-on to this system?

Could you please explain the purpose of diode 86.

Thanks

When relays shut down they "spike", an EMP from the coil of about 200volts.
Without that coil relay and possibly a second on H2/22, band towards the R/S you WILL DESTROY YOUR R/S.
I believe the instructions mention this, they used to on the 5901.
