I'm going to be installing a Viper 5901 in my 2005 Chevy Trailblazer LS in the next couple of weeks, and I have a few questions about D2D interface modules. I'm currently looking at the XK01, as it has the most interface options and will simplify my installation considerably. My Trailblazer is an '05 LS with the I6 engine and automatic 4-wheel drive trans.
In the "Supported Functions" tab on the XPresskit website, the XK01 shows additional support for remote start features through D2D. The main points of interest, for me, are Brake Status, Tach Output, Ignition Status, and RPM Status. Does anyone have any experience with the XK01 providing these inputs for the alarm/remote start? If so, are they stable? Or do they act flaky?
The Supported Functions also includes Defrost and Heated Mirrors. I'm assuming they mean rear defogger, as the mirrors and rear defog are triggered by the same switch in the HVAC controls.
Horn Chirp is also supported by the XK01 through D2D. Is this defeatable? The 5901 can be programmed to only activate the horn during full alarm trigger events, so I'm hoping that the module won't be chirping the horn during arm and disarm cycles. After looking at the Xpress VIP software instructions, it looks like the only thing that it does is the update flash. Is there other software for setting options on the XK01, or does the alarm programming just translate straight through? Ideally, I'd prefer the horn not to function even at full alarm. If I was wiring the alarm/RS directly to the vehicle harness, I could just eliminate the horn connection. Since I'm planning on the XK01, the horn is now handled through the OBD II as a data command.
On another forum, I read a post in which the author said that other than power, ground, and a couple other connections, the alarm/remote start and XK01 could handle everything through the OBD II data line. The remote start could be handled by the XK01 through the Chevy BCM (Body Control Module) and that none of the heavy gauge remote start harness was necessary for the starter function to operate. I am HIGHLY skeptical of this one, but with the amount of system integration, you can never be sure. Is this one a load of crap? I already know what wires I need in the vehicle harness, so it's no big deal. If it will do the RS through the OBD II, it just saves me a little splicing and soldering.
Thanks.

the xko1 is an excellent bypass to use for that truck. and it does do everything on that truck that it says it will do. one hint, don't use the d2d cable, it can act shifty. hardwire your connections from xk01 to viper it is the foolproof way, and it always works. the diagram is on the site. don't think you do not have to hook up your ign. connections, cause you have to. there should be 2 ign. 1 acc. and the 2nd ign. is very important. also if your truck has factory anti-grind you do not need the tach connection, turn off the tach and program the 5901 to do a 4 second crank, it will start in all weather conditions and will not grind the starter. also the 2 back door pins are at the bcm under the 2nd row bench the xk01 only monitors the 2 front doors. have fun and overall this truck is not too difficult.

This thread answered some of my questions, but I have one more to add:
Which circuit is secondary ignition? There is circuit 1390 (acc, run, crank), circuit 300 (ign 3), and circuit 4 (acc).
Help a brotha out....I did a search lol  ------------- 2003 Trailblazer LT

I am not a fan of the XK01 myself. While it's not bad there are better out there for that truck. I like the Idatalink units as they give you practically every wire needed including tach. Beyond that the truck is one of the easiest there are to do. I agree with the statement above, the data ports always seem to have problems. Spend a few extra minutes and hard wire the units together...

I used the XK01 with a Viper 5101, in my '05 Silverado using D2D everything works perfect 100% of the time. I don't have rear doors so I wired the "pink/white" wire with a relay to do window roll-up.

thanks for the reply...Ignition 2 is the same thing as secondary ignition? ------------- 2003 Trailblazer LT

Definitely use d2d. I put one on a 04 trailblazer last week. Just hook up data and it will pick up lock.unlock, fact arm/disarm, horn honk, immobilzer, door trigger, and its kinda neat because the fact remote will now also work the viper. ------------- Advanced MECP

I'm going to try the D2D first. If it acts too flaky, I'll go with the hardwire option. Got the XK01 delivered yesterday. Now I just need to find a supplier who carries the D2D cable. Any recommendations? After some additional research, I can confirm that the author of the post who claimed that the RS could be handled through the databus isn't playing with a full deck... It's just not possible with the Trailblazer ignition system. The RS wires are an absolute necessity. If the Trailblazer had "push button start", it might be a possibility to handle the RS functions through the databus, but it's not happening with the current factory ignition switch setup. The tach and a couple other functions apparently can be handled by the XK01 (D2D only) through the databus, but the ignition, start, and accessory wires of the Viper MUST be connected to the vehicle wiring harness. .

If you are referring to me then maybe ill dumby down my post a little bit. Of course you would have to wire in the relay pack for remote start. Also just to CLARIFY you also have to ground the unit, hook up foot brake, hook up parking lights, tach wire, hoodpin, nuetral safety switch. I was referring to the data functions that can be carried out by the xk01.

No, it wasn't you. You helped push me over the edge towards trying the D2D... The post was on another forum. Basically he was implying that the RS would work on the Trailblazer by only connecting power & ground (on the viper and xk01), neutral safety, lights, the control center, D2D, and the OBD II wire. He was claiming that the remote start harness of the viper was completely unnecessary, as the ignition, accessory, and starter would all be activated through the OBD II signal and the Chevy BCM (body control module).
The "supported functions" tab on Xpresskit's website, shows the XK01 will pick up brake, tach, and hood pin through the D2D. That's why I was interested in trying the data connection first. About the only thing it doesn't cover through D2D is the parking lights. I haven't been able to find out much about the D2D being used, so full details about the level of interface are sketchy. I haven't found any posted instance where the brake, tach, and hood pin signals are being picked up, so I can't verify that it will work like that with my Trailblazer. I'm going to give it a shot and see what happens.
As far as using the D2D, it seems like people are either loving or hating it. There doesn't seem to be any middle ground. I'm going to try the D2D and see how it goes. If it's got issues, I'll swap over to the W2W harness. Then I'm only out a few bucks for the D2D cable and will just have to spend a little more time with the soldering iron...

Interesting. So is setting the tach like this better than using voltage sense? Also can you help me with hooking up the neutral safety wire. I do't see it in this list. Thanks
