04 silverado remote start

Mon 53/47 Tue 56/40 Wed 52/36 Thu 52/44 Very gradual, thus a temperate climate even though we are as far north as Calgary 51N. we have the Gulf Stream to thank for our mild winters (except when we get a Northerly "gift" package from Siberia).

Quick easy question for you guys. I am installing a Viper 5104 alarm w/ remote start in my 04 Silverado 2500 Diesel. I bought a door lock interface and then found out I actually needed a bypass as well for the remote start to work. So I am scraping the door lock interface and bought a Fortin INT-SL+ There are 2 ways to install it, with and without a datalink. Whats the datalink? which way do I need to install it? I don't want any fancy doodie, I just want the keyless and remote start to work, nothing else.-Chris

I am dumb, figured out what it was. I don't know if the viper has a data link connector on it.. I'll take a quick look but I'm going to assume it does not and hook it up the standard way...-Chris

Hi Chris,

The Viper does indeed have a D2D connector on it.  However, while you could find a D2D harness to make the connection, there is a language difference between the standard Factory programmed Fortin bypass module ( DataLink ) and the Viper ( DBI ).

W2W mode is the best way to make the connections between the two units.  Do it on the bench, prior to install and everything will work and the install will be neat.

I just went ahead and did it the hard way... haha, thanks.-Chris

I thought I had everything figured out but now have one last issue. I am installing a Viper 5104 alarm w/ remote start in my 04 Silverado 2500 Diesel. Truck starts then immediately shuts off. Now I know this is because of the passlock system and the bypass isn't doing its job. I programmed it exactly the way it tells you to and it seems to work fine. Light comes on, then blinks and then shuts off (with proper inputs in between) I hooked it up according to the directions from their website.. but nothing in their diagram mentions hooking any wires to the 2 wires in the steering column for the passlock. Does it get all this information from the obd2 connector? Also, in the wiring it shows to hook the door trigger wire from the alarm to the bypass, but the alarm is only triggered by the drivers door and then the drivers door will no longer trigger it until you start it and shut it off. According to the INT-SL+ directions I can also get my tach signal from this unit. Thats the way I have it hooked up, and it seemed to program fine.-Chris

The Fortin INT-SL+ handles the Passlock2 thru OBD2 Data.  No Passlock2 wire connections necessary.

Two thoughts on this issue.

1.  Does your "Tach programmed fine" statement mean that the Viper Tach learn process gave a successful completion signal?   While the install guide indicates that the properly programmed module will provide a Tach signal, other manufacturers bypass modules ( iDatalink ) state that the Tach signal is only generated on non-DuraMax engines.  Might want to check with Fortin to see if the INT-SL+ will provide a Tach signal with your diesel engine.

2. If you went W2W ( hardwired all wires ), verify that the Vipers Blue (-) 200mA Status Output wire is connected to the INT-SL+ Blue (-) While Running wire.

When I say it programmed fine, I mean it gave a single confirmation flash which is supposed to mean "an analog signal has been programmed" as opposed to 2 flashes which mean "a d2d signal has been programmed" Yes the blue status wire is hooked to the blue (-) when running wire from the int sl+ Also forgot to mention that with it running I can activate the remote start and remove the keys, I don't know if that is relevant or not.-Chris

Should I try pulling the tach signal from the back of the cluster instead?-Chris

Being able to do "Pit Stop" mode is a good sign. 

Yes, I think trying another tach source and re-learning the Viper Tach is a good idea.
