03 Trailblazer Aatra 1000RS Gmdl-bp Installed a a remote start in this vehicle 2 weeksago, it's been working fine since then. This morning I go out start the car, locks are pulsing by themselves, I don't have any control over them via the door switch or the remote on the RS I reprogramed the bypass and all seems to be fine again, anyone else have this problem and could you possible shed some light on why it is doing this,will it happen again and is there a fix for it ------------- RFD

Trilogics GMDL-BP For a 100 bucks I was hoping there would not be any problems with it. It is hooked to the 2nd wire (purple ) in the OBII plug,I used a crimp connection on it , I'll solder it tomorrow, I took a few easy steps and used T taps and crimps , seems to be working ok now, but I can't keep pulling it apart to stop the locks from pulsing ------------- RFD

i have noticed that on a lot of gm vehicles the resistance if crimps makes things screwy . i use them to , it seems faster but not when u have to pull it apart a few times . i have use the crimestopper module and the dei 457g and both i had problems with . i fixed them but still they have problems ,

T-tabs add resistance, never use it in a bypass like that. Sodder all your wires. The quickest option is not always the best. I sodder all wires and tape them, even when using caps.

T-taps belong in the same dumpster as crimp caps and Scotch-Loks..... preferably on fire as well.
They are not a reliable connection. At all. Ever. Plus.... they look like shhh under a dash..... learn proper connection methods that involve wire on wire. IDC are not quick and easy when a vehicle comes back in with a stupid, intermittant fault......
Now, on to the GMDLBP thing.... I have heard of a couple of them freaking out in this way. Reprogramming usually took care of it.... also... make sure it has a good ground. Try grounding the piece to the ground that is on the OBD connector. If the computer is referencing to that ground, then your data signal should reference to this ground. Gotta remember, this IS a GM, and as of late, they do not have the most stellar grounding out there. The piece of steel you may have grounded to may have become slightly less than ground over time....

Thanks guys!!! I 'll solder all connections Monday , and reprogram the gmdl-bp, along with finding the perfect ground. I love reading all these tips you give out, I ve learned so much from them , haven't worked in a shop in over 30 yrs , I've been a flatfoot for 30 yrs,getting ready to retire and bought myself a toy to play with. I still love working on cars and just replaced axles in my daughter's airhead boyfriends jeep. The putz thought all the grinding was a bad set of rotors ,not busted cv joints!!!!!! and he wondered why there was no power on the freeway duh I love reading and you guys are such a great group to learn from , learning is a fun thing.except for the few who throw digs at those that try to learn I'll let you aLL KNOW HOW THINGS WORK OUT ------------- RFD
