i am currently installing a design tech remote start in my 06 ls balt. i have the interface module and the key is in place in the box. i also have the loop around the ignition loop for the transponder. i also just found out today that our cars dont have an ignition 2 wire from the key. so i have the ign. 1 (yellow) and the acc.(brown) and the constant, ground..etc. but my car will not start. it is not a problem with key recognition because i put my other key in the ign an hit the button. it doesnt work!!! please help anyone that has some experience.


ps already searched and my question is not out there. thanks for helping

 

Unless GM changed their wire colors. I don't believe that the yellow wire is an ignition wire. I believe that it is usually a starter wire. If I remember correctly, pink is usually the main ignition wire.

 

the only wires are
red/white-constant 12V
yellow-ignition 1
white
white/black- both white and white/black are for the keysense

anyone know whats wrong with my install?

 

If its the same as the 05 there is a second ignition. I believe its pink w/ white stripe, but im not positive on the color. just test the wires with a test light, see which wire turns on with the ignition and then turn off the key, The second ignition will stay on but will turn off when you open your door.

 

Do you have the keysense wires connected as well for the loop of the bypass module??? Try turning the ignition key forward to the on postion, not the start position. Then try the remote start. If it starts that way, you don't have the second ignition wire energized. I wouldn't go probing around with a test light if you really don't know what you are doing either, because if you hit an airbag wire, it will deploy. They deploy by being grounded and a test light will ground the airbag system.

 

yes...i know about not using a test light. i have a snap on vantage meter. the only wire there is a red/white .... not pink/white. that is the constant power. the remote star foes not work with the key to the on pos. the loop is in place and around the cylindar next to the factory loop.

 

bump for anyone awake at the ungodly hour of 10 am lol

 

there are no airbag wires where these wired are. Are you grabbing the wires by the fuse box? Thats where you will find the second ignition.

EXTRA INFORMATION
NOTE *1 the BCM is part of the FUSE/RELAY BOX on the front PASSENGER SIDE of the CENTER CONSOLE. The BCM has the following connectors: C1-72 Pin GRAY Plug, C2-72 Pin GRAY Plug, C3-41 Pin RED Plug, and C4-68 Pin LIGHT GRAY Plug, the C4 Plug, is located on the BACK of the BCM. NOTE *2 the PCM (Powertrain Control Module) is located on the DRIVERS SIDE FENDER, in FRONT of the UNDER HOOD FUSE BOX. The YELLOW STARTER wire is NOT required for REMOTE STARTING. When the Vehicle sees VOLTAGE on the IGNITION #1 wire and the ACCESSORY wire loses voltage the vehicle will automatically CRANK the STARTER on the vehicle. NOTE *3 This vehicle uses a 1-Wire Door Locking System that will require extra parts. The LOCK requires a Straight (-) Negative and the UNLOCK requires a (-) Negative thru a 1500 Ohm Resistor. Some units will also require (2) extra Relays Part #775 for this function, to connect See DIAGRAMS. NOTE *4 The DRIVERS DOOR is a GRAY/BLACK (-) Pin 22, The PASSENGERS DOOR is a TAN/WHITE (-) Pin 19, The DRIVERS REAR DOOR is a LIGHT BLUE/BLACK (-) Pin 1 and The PASSENGER REAR DOOR is a LIGHT GREEN/BLACK (-) Pin 20, when connecting to an ALARM SYSTEM use all 4 wires and DIODE ISOLATE, to connect See DIAGRAM

 

Looks like the constant power is Red/Black and not red/white or pink/white. Check and make sure that the remote start is sending or energizing the ignition wires when you push the button on the remote. Check them with your test light.

 

they are getting the correct power..... i dont know if i can get a ign. 2 wire near the fuse box. the key sense is the wire that powers the ign 2 wire.

 

okay if anyone wants to put a remote start in for their cobalt...even if it is a stick shift let me know. i finally got it working. i ran the starter wire from the remote start box to the starter selonoid in my car. since i already had the ignition wires working fine, the car cranks and starts perfectly. thanks to all that tried to help. but most of all thanks to my dads old buddy at gm. he told us exactly how the ketsense worked.

 

Hi, I have a 09 g5,, what wires did u use in the ignition panel to get your remote start to work,,, I have a 556u key in the box set up,,,, the only time it works is when I turn the key to the o position ,press the start button and remove the key it starts up, for a minute and dies...I k ow it's a noon question but trying to get it right,,, thanks
