Josh,

I've got the 2011 Helm set on the Caprice, but not for the 2012. Don't think there's a whole lot of difference though. Give me a call and we can look through the manual....

The RCDL module is under the package shelf trim panel inside the cabin.

My mind isn't working correct. What is the TDM module?

I believe it is the theft deterrent module. I am trying to get my remote start working correctly. I can't find a local dealer that is willing to help out so I am having to send parts to Chris White to finish the rest of the setup. Just trying to cover all my bases.

From the service manual
Theft Deterrent Module (TDM)
Vehicles with steering column mounted ignition switches have the exciter integral with the theft deterrent module (TDM), which is located within the steering column. The TDM can learn up to 10 keys (transponder values).

The TDM uses the following inputs:

•Battery voltage
•Ignition switched voltage
•Ground circuit
The theft deterrent control module uses the following outputs:

•Password exchange
•Challenge/response with the engine control module (ECM)
When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the TDM. The TDM then compares this value to the learned key code stored in memory. The TDM then performs one of the following functions:

•If the transponder value matches the values stored in the TDM memory, the TDM will send the prerelease password to the ECM via the serial data circuit.
•If the transponders unique value does not match the value stored in the TDM, the TDM will send the fuel disable message to the ECM via the serial data circuit.
•If the TDM is unable to measure the ignition key transponder value, the TDM will not send any messages to the ECM.
