code alarm ca6225

I fixed the parking light issue, it was a bad splice connector. The lock issue remains. I even tried to use a new 1k resistor, but no joy. There is a 1k ohm resistor soldered in line on the green wire on the 451m and after the resistor the blue and green wires are connected together and the tied into the same lock wire. The connection has to be good sine it's locking properly...I'm at a loss....

Ground the green between the resistor and the 451, see if that works. N.B. Make sure you have your lock and unlocks the right way round. You need to do a lot more testing.

I just tied a ground into the green wire between resistor and 451m. Everything else alarm wise seems to be working properly. I can't do the remote start until I pick up,another key, so I can't test that portion.

And did that unlock the car? If it did the relay is at fault (almost impossible IMO), if it didn't you've done a bad joint. P.S. How are you joining cables?

Unlock is working fine, it's just not locking. I've used solder to connect harness wires that have the same point, direct wire. One tin with wire nuts at the ignition harness and quick splice connections at the BCM.

I jus be sleepy...geez. The connections with the resistor and unlock/lock wires is all solder and quick splice to the wire at BCM.

Ok, now I'm really confused. I disconnected the lock wire from the 451m, but the Unlock when disarming still works!! How is that even possible? Is it using the factory arm / factory disarm wire?

Ok...so I went back and re-did all of my connections and it now locks! But now it won't unlock....when I put the key in the ignition the doors unlock though. Does that point to the factory disarm connection? I tested it and it seems good.

I answered my own question, now I see why people don't recommend using quick splices. I'm confident now that everything is ok. It's Miller time!! But seriously thanks to both of you guys for all of your help, I wouldn't have got this done if it weren't for that. Now I'm off to flush mount some tweets and clean up / reassemble the car.

That's good news.  Glad it's all working correctly now. 

A quality solder connection is a thing of beauty and a joy to behold. 

Soldering is fun!
