I installed a remote start on my 02 chevrolet avalanche...

1st ignition is wired to pink wire.
2nd ign is wired to white wire

when wiring for defroster to I simply unplugged my 2nd ign for a second to test wire to see if constant power was on white wire (2nd ing) white vehicle was running.

Then I plugged my accesor wire into the Orange wire.

the replugged the 2nd ign back into the white wire.

My check engine light came on ...haven't moved care a inch. I read on here about drive train indications when 2nd ign isn't used. I called onstar and the diagnosed it as a drive train warning..

there fore i checked wiring, everything seemed fine. I then unplugged completely remote starter unit.
DARN light is still on. therefore I disconnected battery for a minute, and it still was on after restarting.

IS THERE A FUSE? OR A RESET? I'M ABOUT READY GIVE UP. posted_image

I'm using an omega 4lx, with my factory remotes, its seems to work great.....as for wiring, it seems compatible to other remote starts as far as main haress colors (constant, starter, 1and2 ign., acces,

please help ? it would be truely appreciated.

You have to unplug the battery and wait 5 minutes if you want to plug everything back (remote start) make sure all conections are made pink is ign, white is 2nd ign , orange is acc, brown is 2nd acc, red 12 v. must the time the check engine still on, so you have to drive the car and the check engine should disapear. it happened to me. make sure the gas cap is close sometimes the check engine came on for that reason.

Usualy there is no possible reset without a scan tool . but I ever see somewhere that if you leave the battery disconected for 1.5 hour it will reset by it self. (I am not sure of this one but it worth the try compare to the dealer fee to erase that code. If you have to drive the car do it slowly.

AS long as you have your 2nd IGN (white powered up) when the truck is started you won't have any troubles.. It is when the RS starts the truck and the white sees no power, you turn the key and hit your brake to stop the RS and have the truck take overis when you have to worry. It's a timing thing. If you just start the truck with the key, you won't have any troubles (even though the idiot light is still on) But try disconnecting the battery for 5 min or longer and that should take care of the light.. But if you don't have the white wire hooked to your remote start.. DON'T drive the truck... you could blow the transmision!!!

well i started it with key, after unplugging battery for 5 minute , light was still on, drove it around block....and it shifted fine it seemed but light did not go off. maybe I should try 1.5 hours like user: Montrealler said.

I can relate to the issue..once you hit brake vehicle should take over command totally. I really think it is a idoit light reset problem. as I mentioned before I totally disconnected wires from RS I tested white wire while RS was running vehicle and it had power.

It was my stupidity for starting it with remote start after i unplugged the 2nd ignition...for some stupid reason. I wanted to test my 2nd ingnition through the contact in the t-tap instead of probing it. Stupid., i should have just gone with the my RS accessory wire to vehicle accessory #1 by the book. Stupid.

I really don't think it is a tranny problem., just would like to reset let to see for sure. I even called Onstar and they said have so many asking to do it...but they can't either, they can just read the diag. codes.

Thanks for you help. I agree i think light is just stuck on ....anyone's input would be appreciated. thanks.

JUST CALLED ADVANCE and autozone, they said they would reset code for me for FREE... everyone this is a good thing to remember incase we need it in future. instead of paying dealers huge fee.

STILL IF ANYONE has any info on whether or not i'm on target please let me know.

I ran into a problem like this, with an 03 s10. I had to power up the 2nd accy (brown) and the light went away. just a shot in the dark though

would be nice to not have to power 2nd accy wire. do you know approx. what is powers on a chevy../and or avalanche...defroster seemed to work fine with 1st acc only...
though you may have a point...
guess i'm going to drop by advance in morning to reset code to see if i'm ok....if not I'll attack the brown wire angle.

thanks so much.

Ok try this.....make sure you power on both ignitions and both acc. during remote start. I haven't ever had this problem but the vehicle may think there is a problem because both acc. wires aren't powered on when the vehicle is running.

I have never had a Chevy's CHECK ENGINE light go on because I didn't power up the BROWN ACC wire. This wire doesn't power anything up that is necessary for the truck to operate properly other than the wiper's, radio, etc......

Most of the dealerships around here just clear the code for you when you bring in the vehicle for an oil change. They will tell you that the light tripped and there was no other problems and they clear the code for you. It doesn't take any time for them to do this and if your in good standing with the dealership, they will do it for free.... hopefully.

Actually, 05 Duramax needs the brown accessory powered.... it powers the cluster, wipers, radio is bussed. Also, Class2 Crapaliers and Sunflowers like to see the brown powered (no second Ign, just 2 Accy.)

Would a 99 s-10 2.2 be the same as the "crapalier" with these wires?

Hey Gus, if not powered, do you know what errors you would get ? Aside from no working dash & wiper's/radio ?

to all those who replied to my post...thank you.

I went by autozone today., and they reset the code for me for FREE...I was honest with them and they weren't busy...if they are busy, i'm sure one can just go in and ask them to read the code as they have a policy to read them for free. then after reading it ask them to reset it to see if it comes back on.... In my case i just tripped the drivetrain code by unplugging my T-Tap connector and accidently starting the RS. As for the 2nd Access, it wasn't required in my situation...

Good piece of info, if you don't have the equipment to reset the code...Autozone/Advance can help instead of dealing with the dealerships.

thanks again to all.

I haven't seen it pop a code on the J-body cars ( I think that's what they are properly called...), but on the Duramax, it came up with a "charging system error" or something to that effect on the cluster. Powered the Brown accy, and away it went. Might be just the Diesels... haven't seen it on the 05 gassers.

Kinda one of those "safe than sorry" issues. I do the extra accessory on the cars as more of a just in case situation. No second ignition on them anymore, may as well use that second ignition output for something.

Did you really use T-Taps for your ignition \harness connections?

starter is yellow
12V is red
Accy is orange
white is brake
blue is parking lights

ok, thanks. I have looked at a few wiring diagrams from a few web sites and they all have differed a little. Just trying to clear things up.

sounds like the 2nd ignition wire isn't power up by remote starter, ign wires are purple & white. if not done right transmission damage can occur if the right senario happens.
