Installation and Programming Issues
See Figure 2 for locating and verifying the red LED (4) indicator light operation.
  • Verify internet connection and that the latest software is being used. Click > Check For Updates on the Screamin Eagle Pro Street Tuner home page to verify that all available updates have been downloaded.
  • Connect VCI to DLC of vehicle. Connect VCI to computer using USB cable.
  • Turn ON the IGN and RUN switch while observing the red LED on VCI. If the LED does not illuminate for 1 second at key ON, check for power and ground to DLC of vehicle.
  • If power and ground are present, install a new cable from VCI to DLC. If LED still does not illuminate for 1 second at key ON, try a new VCI. Refer to Table 1.
  • If LED does illuminate for 1 second after key ON, look to see if the icon in the lower-left corner of the screen is showing connected to vehicle and computer (green).
  • If icon is red on screen, which indicates it is not communicating, then go to add hardware in control panel and add new hardware.
  • If unable to detect new hardware or icon is still not green, install a new USB cable and retry.
  • If unable to obtain a green icon after replacing USB cable and attempting to add new hardware, replace VCI, and retry adding hardware.
Refer to Table 1. A good VCI will illuminate red LED for 1 second if power and ground are present at the appropriate pins. Use table to find at which pins power and ground will be present for your cable.

How to Troubleshoot VCI
PROBLEM: I cannot get computer to display diagnostic trouble codes.
PROBLEM: I cannot get computer to display System ID numbers.
PROBLEM: I cannot clear Historic Fault Codes.
1. Check lower left corner of Screamin Eagle Pro Street Tuner software screen. If VCI Status link indicates that VCI is disconnected, it means VCI is not communicating with the computer. Check items 2-7 below to see if there is a physical or electrical problem.
2. Check cable between computer and VCI. Make sure connections are clean and tight. Check cable for cuts or other visible damage.
3. Make sure VCI cable is plugged into correct receptacle of computer.
4. Check cable between VCI and vehicle DLC. Make sure connections are clean and tight. Check cable for cuts or other visible damage.
5. The VCI obtains its power directly from the vehicle. Make sure the vehicle's battery is fully charged, the ignition switch turned on, and engine stop switch is in the Run position.
6. To reset VCI, unplug DLC from vehicle and then plug it back in.
7. Make sure vehicle's battery voltage is greater than 11.5 Volts. If it is not, the vehicle's ECM may not be able to communicate properly with the VCI.
PROBLEM: I cannot reprogram VCI.
1. See Q&A section above and follow the seven-step procedure to verify VCI is receiving power and operating properly.
2. Before attempting to reprogram VCI, make sure the Screamin Eagle Pro Street Tuner software is the ONLY program running on the computer. Exit all other programs. Even if another program is minimized, it may interfere with the VCI reprogramming process. The only button that should be visible on the task bar besides the Start button is the Screamin Eagle Pro Street Tuner software button.
3. Make sure VCI is in reprogramming mode. Make sure you have followed ALL the on-screen instructions in the order in which they appear. If you followed the instructions and reprogramming failed, DO NOT assume the VCI is still in reprogramming mode before you restart the reprogramming sequence.
