available, The type of data available, and the order in which the groups are listed varies by

model. A typical data group listing would include:

• Oil Information

• Adaptation Values

• Speed Regulation

• Fan Status

• Start Enable

• Values at Idle

• Air Conditioner Values

• Lambda Pairs

• Lambda Control Downstream

• Lambda Control Upstream

• Engine Running Values

• Air Pump Values

• Knock Values

• Injection/Ignition

• Spark Current 1—8

• Fault Counter

• Cruise Control

• Running Temperature

Combining data into groups results in a much shorter data list and allows for a faster update rate.

Functional Tests

Selecting FUnctional Tests from the Main Menu displays a menu that varies depending on the

vehicle identified.

Each selection from the Functional Tests menu allows you to activate and test various

components and systems of the engine management system.

Actuator Tests

Actuator tests command the ECU to activate components and systems, such as injectors, the

throttle valve, adaptive strategy, or the fuel pump. The Scanner displays only those tests

available to the identified vehicle and system (ECU).

For many components, you can conduct an auditory test—a relay clicks or a pump vibrates. Be

aware that actuators can be mounted anywhere in the vehicle, such as under the dashboard,

hood, or trunk.

If you hear no reaction where one is expected, test the actuator circuit with a digital multimeter or

a digital graphing meter such as the Vantage PRO™ Meter. Use these instruments to confirm

whether the ECU properly controls the component.
