2005 cobalt, xk01

can you get the xk01 into program mode? seems everything you're doing is correct; your unit may be defectiveThis information is provided only as a reference.

All circuits should be verified with a digital multi-meter prior to making any connections.

The instructions state that i can program modes 8 and 9. I was able to enter the programming mode and change the options through the remote but that did nothing to make the unit work in the car.

never mentioned, but what are you installing that requires the xk01? how is it connected to the xk01? d2d or w2w?This information is provided only as a reference.

He wants it for door locks and trunk.  He doesnt need that interface.

Yeah, I don't really need it. I just figured since I have it I should use it. Also, I haven't done much with relays before so I thought this would be easier. Oh well, thanks for the help and fast responses.

Understood but what brand and model system are you using with the XK01? D2D? With the amount of time invested it may be easier to pick up the two wires at the BCM. The door locks are a single wire resistive system. Lock = White = ground @ BCM pin#6 or 7 of C1 connector. Unlock = same wire as lock = ground through 1.5K resistor Trunk release = Tan = ground @ BCM pin# 10 of C2 connector.This information is provided only as a reference.

It's an Amenity re4 module and it was hooked w2w. Also, I have the door locks working by tapping into the white wire directly like you said.    I want to hhok up the trunk release, the keyless entry sends out a 300 mA negative pulse so I imagine I would need a relay for that, right?

correct you should use a relay to ensure that it works consistently. i think you may have a defective xk01.This information is provided only as a reference.

If u don't mind me asking, what's the correct way to wire the relay?

You dont need a relay for the trunk pop, the module sends out a ground, and the BCM needs a ground to trigger the trunk pop.

If you DID want to use a relay... 85 & 86 are the coil to energize to activate the relay, so one gets + and one gets -

Then.. whatever you're sending into #30 (yellow).. will come out #87 (brown) when the coil is energized.

BTW WITHOUT the coil energized, whatever you're sending in 30, will be comming out 87A, and when you energize the relay, that connection is BROKEN and 30 will come out regular 87
