Viper 5706V With Omegalink Bypass Module, 2007 Nissan Titan

I mean exactly that. You need to use your multimeter and see if it shows ground during remote start. I don't understand the anti grind issue. Is this during remote start? You said the starter wire doesn't have output so I'm confused. I don't know what is causing your brake error but you might try disconnecting your interface first and trying with the key in the ignition.

The grinding was after remote start of the vehicle. When I jumped the 12 volt contant to the violet stater output wire it didnt have any voltage. The starter wire that didnt have any voltage is the violet wire on the 10-pin heavy gauge connector during remote start.desertislandertech

When I performed the test to RS with key in ignition, the truck started but after a few seconds I heard a grinding sound like it came from the starter so I shutdown the truck right away. The interface I am using is the Omegalink OL-MDB-ALL which flashed successfully for my truck. The Omegalink website states the "Omegalink's flagship web-programmable 'all-in-one' CAN interface. Supports data immobilizer bypass and door lock integration for over 3400 vehicles 1997 to date including exclusive KLON firmware applications. Features single-wire connection to Omega and related remote start, vehicle security and convenience products equipped with a 'DBI' serial port." desertislandertech

If it only remote starts with the key in the ignition then you have a problem with the interface. I know you said you flashed it. Did you also complete the programming at the end of the Omega install pdf?

I did reflash bypass module and yes completed programming with no errors. When I tried to do remote start thats when I had the error 5 flashes for brake active. I am not able to test RS because of the error for the active brake. So now it shows error on the RS key fob display when trying to RS.desertislandertech

Hmmm. You could try programming it wire to wire instead of data. If that doesn't work, I would probably try a transponder only bypass (even a cheap key in box type from the auto parts store) just to ensure the issue is with the interface. I keep one around for troubleshooting.

I may try W2W and see if it works. Although it shows in the Omegalink wiring diagram to connect all RED dotted line wires, I assume I won't need Trunk. There is no Ground While Running wire on my RS but the is one on the Omegalink bypass. Does this go to ground on the vehicle? There is also a ground wire on both the bypass and RS. Assuming just ground it to the chasis? There is also the hood wire and a note "With OEM Switch Only". my vehicle does not have a factory hood switch. Do I need to connect this wire to the hood switch that came with the RS?desertislandertech

Your Viper has a couple ground while running wires, they are just labeled status. They are typically used to ground a key sense wire if needed, or to provide a switched ground signal to an interface like the Omegalink, during remote start. For the hood pin, if there's not a factory switch you can install the one it came with.

Let me rephrase my question. I already imstalled and connected the RS hood switch wire but do I need to connect the hood wire from the Omegalink to the RS switch? I'm assuming that since I will be connecting via W2W instead of D2D it would communicate between the RS and Omegalink. Regarding GWR wire, where is this connected to? Are there any other wires from the Omegalink bypass needed to be connected to the vehicle or are they all connected only between the RS and the Omegalink bypass?desertislandertech

The Omegalink shows a hood status output, so since you don't have a factory hood switch, there's no need to connect it. The ground while running output from the Viper would connect to the ground while running input on the Omegalink. Just follow the diagram in the installation instructions and you should be good.
