a series of choices. Simply follow the menu driven procedure, and make proper
selection each time; the program will guide you to the diagnostic function menu after a
few choices you’ve made.

The Function Menu options vary slightly for different vehicles. The function menu may
include:
⚫ ECU Information – provides the retrieved ECU information in detail. Selecting
opens an information screen.
⚫ Read Codes – displays detailed information of DTC records retrieved from the
vehicle control module.
⚫ Erase Codes – erases DTC records and other data from the ECM.
⚫ Live Data – retrieves and displays live data and parameters from the vehicle’s
ECU.
⚫ Active Test – provides specific subsystem and component tests. This selection
may appear as Actuators, Actuator Test, or Function Tests and the tests options
vary depending on the manufacturer and model.
⚫ Special Functions – provides component adaptation or variant coding functions for
custom configurations, and also allows you to reprogram adaptive values for
certain components after making repairs. Depending on the test vehicle, this
selection may sometimes appear as Control Unit Adaptations, Variant Coding,
Configuration or something similar.
