TROUBLESHOOTING

Installation and Programming Issues

NOTE

See Figure 6 for locating and verifying the red LED (4) indicator light operation.

Verify internet connection and that the latest software is being used. Select > Check For Updates on the SE Pro Street Tuner home page to verify that all available updates have been downloaded.
Connect BCI to DLC of vehicle. Connect BCI to phone or computer using bluetooth. Also can connect BCI to computer through USB cable.
Turn ON the IGN and RUN switch while observing the red LED on BCI. 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 BCI to DLC. If LED still does not illuminate for 1 second at key ON, try a new BCI. Table 2
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 BCI, and retry adding hardware.

NOTE

Table 2 A good BCI will illuminate green LED for 1 second and once paired will stay green.

How to Troubleshoot BCI

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.

SOLUTION:

1.	Check lower left corner of SE Pro Street Tuner software screen. If BCI Status link indicates that BCI is disconnected, it means BCI 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 BCI. Make sure connections are clean and tight. Check cable for cuts or other visible damage.
3.	Make sure BCI cable is plugged into correct receptacle of computer.
4.	Check cable between BCI and vehicle DLC. Make sure connections are clean and tight. Check cable for cuts or other visible damage.
5.	BCI 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 BCI, 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 BCI.

PROBLEM: I cannot reprogram BCI.

SOLUTION:

1.	See Q&A section above and follow the seven-step procedure to verify BCI is receiving power and operating properly.
2.	Before attempting to reprogram BCI, make sure the SE 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 BCI reprogramming process. The only button that should be visible on the task bar besides the Start button is the SE Pro Street Tuner software button.
3.	Make sure BCI 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 BCI is still in reprogramming mode before you restart the reprogramming sequence.

PROBLEM: I cannot tell if I am connected to the BCI.

SOLUTION: LED light constantly on.
