you can buy a knockoff MDI usb to obdii adapter, and get a subscription to ACDelco's TDS service for your truck's vin, and using a windows laptop, program it yourself. If you already have a win laptop, the cost of the mdi + 2 year subscription is probably not much more than about what the dealer will charge you, and if you get it, you can also get and/or "find" Tech2Win, and then you have the dealer-level diagnostic tool for your truck,where you can get codes from all the computers in your truck, perform all the diagnostic tasks in the full service manual that need a computer to do them (such as bleeding the abs system, injector leakdown tests), and w the TDS subscription you can reprogram all the different computers (w stock programming), install some radios in it (ie, if the radio is vin locked, you can reprogram the radio to work w your truck), and a bunch more stuff.

 

Techstream will have 3 different options for programming the RCDL module. You have to visually look at the module, to know which method to use. You will understand what I'm talking about when you start the process. If you call up acdelco, they are pretty good about helping.

Did your truck come factory with remote start, and now it doesn't work? Or are you adding factory remote start.

 

I am doing some much needed repairs after owning the truck about 10 years. For the last five or so the TPMS has been jacked up and the remote start wasn't working. The TPMS all of a sudden thought it was a dually, and gave readings for Left right rear tire low etc. Research led me to the RCDLR receiver which I have found and replaced, but my launch creader doesn't seem to have the ability to re-program.

 

Buy an MDI clone like Dave said. You need a device that works with techstream. Tech2s no longer work with service programming ever since techstream rolled out. Couple other devices will work too. I have this among some other ones.

It's $200 and is well worth it. You can use bosh drivers with it. So no bootleg software. You can get some cracked versions of tech2win and GDS2 which work great. Just cant have them installed on the same operating system as your using with techstream to program modules.

A buddy with a 3/4 ton suburban had similar symptoms, he replaced the aftermarket stereo with a factory one and fixed it. Not saying that all aftermarket stereo interfaces will cause it, but his did.

 

Also your remote start will not work if you have certain modules throwing codes.
