Select the vehicle make, year, type, model and engine size by highlighting the appropriate information. The Chevrolet HHR is considered a light duty (LD) truck. The engine size can be determined by a tag in the engine compartment. This HHR is equipped with the 2.2L L4 engine.
At this point, the next screen appears, indicating that all power consuming devices must be shut off, and to turn the ignition on.
The Tech 2 then reads the Vehicle Identification Number (VIN) and the ECU data. When completed, the VIN appears on the screen as well as hardware and software numbers. At the bottom of the screen, the Tech 2 indicates that the ignition should be turned off and the Tech 2 should be connected to a PC.
Since we are at a GM dealership, we connect the Tech 2 to their computer system using the RS-232 cable. The Tech 2 is turned on and the on-screen instructions are followed to upload the information.
A choice of supported controllers is listed including the V.T.D. Vehicle Theft Deterrent Learn. From the provided list, select the appropriate learn procedure. At the bottom of the computer screen, the History indicates that we want the Vehicle theft Deterrent Learn for learning replacement keys. It can take several minutes for the information to download from the server.
Once downloaded, connect the Tech 2 to the HHR. The screen offers a choice between requesting information and programming the ECU.
Prior to programming the ECU, the ignition must be turned on and any devices must be turned off. The battery must be fully charged.
The vehicle then reads the information confirming the VIN and the ECU data. The information is vehicle-specific. The programming time is a little more than 12 minutes.
We also programmed the vehicle using the 10-minute sequences. A properly cut STRATTEC 692931 key was inserted into the ignition lock. The key was turned to the “On” position. The anti-theft system indicator illuminated on the dashboard. The watch timer was set to ten minutes and started. Around the ten minute mark, the anti-theft system indicator extinguished. The key was turned to the “locked” position removed and re-inserted. The key was turned to the “On” position and the anti-theft system indicator illuminated. Around the 10-minute mark, the anti-theft system indicator extinguished.
Occasionally, a General Motors vehicle will not require all three of the sequences. This vehicle accepted the key's transponder value after the second 10-minute sequence. When the key was turned to the “On” position the third time, the anti-theft system indicator illuminated and almost immediately extinguished, indicating the system had accepted the value. The key would start the engine and the vehicle could be driven.
Transponder programming for late model vehicles is not always easy. Programming information has usually not been made available on some of the newer models. This problem is not specific to...
