07 g6 ignition, accessory

Just recently put a remote start in a 07 g6 using an excaliber rs-210 and bypass pkucg2x Diagram D. I have used both of these several times on various gm vehicles but this is the first time on a g6. The problem i am having is that the pink(ign.) and brown (acc.) wires in the green plug on the ignition cylinder dont have any power. On other gm models these wires had power. I completly unhooked the ign. and acc. wires from the remote start and car still remote starts and everything works fine-(Heater etc.) but when i try to change some of the programming options i had to pulse the remote start ignition wire cause it wasnt doing it with the key. To access the programming options you have to turn the key on then back off. So is there somewhere else to hook into the acc. and ign. or do these wires even need to be hooked up cause everyting is working?!

The alarm requires an ignition signal for programming operation:

Ignition

pink

+

ignition harness or BCM, C4, pin D3

There is no power on the pink ign. wire at the green plug at the harness or the bcm C4, pin D3. no matter what i do those wires dont show any voltage whether you use the key or the remote starter.

Are you using a meter or a test light to check for voltage?

I always use a digital meter.

Just checking, those wires should have voltage on them.  They are not capable of supplying any current over what they provide to the vehicle.  They will not provide enough current to light up a test light.  I just find it strange that there is no voltage on the wires.

Beleive me i find it very strange i have never seen this at all. but the remote start works just fine and the ign. and acc. are not even hooked up! i even went back to the shop just to test them again. the only wires i have hooked are the start and 2nd acc that are hooked to the white wire in the green plug at ign. harness. i wired it just like the pkucg2x diagram D says like i have many times before with other gm vehicles.

Checked a third time using a different meter before i bring this car back . Definetly no power on the pink , brown , or even the RED / white that is suppose to be 12v. (Green plug at ign. harness)  Somehow it still works just fine other than there is no ign. source hooked up to get into programming mode. I have to do it manually. Am i going crazy or what? Does this mean that it is all controlled by the white and WHITE/ black wires in the ign. harness? (green plug)

no ignition at a cigarette lighter or anything else. i think there is also an ignition at the brake switch but dont quote me on that

not sure. i didnt check.  its just bugging me that there isnt any ign. at the ign. harness.

You might want to check that your DMM is correctly setup and verify you have a proper ground.

I did find a pink and brown (in plug c4 but isnt the d3 pin - C4 d3 doesnt have voltage at all either) at the bcm that act like ign. wires but didnt hook into them because they have voltage when the key is in the on position like its suppose to but also has voltage when remote starting with no ign. or acc. hooked up from remote starter.

used a dmm hundreds of times. it is definetely setup right and definetly works. tried a second dmm just to be sure. there is definetly no voltage on these wires.

White and WHITE/ black definetly control acc. , ign. , and starter. there is no power on any other wires in ign. harness. (green plug) not sure about all g6 's.

This sounds unusual, but if there's nothing malfunctioning on the car(gauges would be the first place I'd look at if I found this) it doesn't seem like anything to worry about. It's definitely conceivable that starting could be controlled by the white and WHITE/ black MUX wires and the immobilizer receiver.

For your programming purposes, the pink wire which you've found at the BCM would probably be the best choice, since pink is GM's traditional Ignition 1 circuit color.
