154 Appendix B Troubleshooting This chapter contains information for troubleshooting specific problems that may arise when using the scan tool. B.1 Communication Problems When the scan tool is unable to establish communication with the control module in the vehicle under test, or when the communication is interrupted, a message will display. If this happens, wait to see whether the communication is established again or interrupted. If communication is interrupted again, press N to abort. NOTE: i Switching the ignition off-and-on and reentering the ID may reset communication.
