The Datastream function lets you view live ABS and air bag data from a vehicle’s electronic control unit (ECU). This chapter describes how to use the Data-stream function.

About Datastream

Datastream is the communication of information between the sensors, computer, and actuators (switches) on a vehicle. The sensors monitor the vehi- cle systems and send data to the vehicle computer, the computer uses the data from the sensors to determine if any vehicle systems need adjusting. If so, the com- puter converts the data into commands and sends the commands to the actuators. The actuators then convert the commands to mechanical actions that adjust the vehicle systems.

As this stream of data is being communicated in the vehicle, the software can read the vehicle computer and display the data information in a readable format, called datastream. This lets you view “live” sensor and switch readings.

Automatic Diagnostic Code Triggered Record

The ABS Air Bag 2004 software has an automatic Diag- nostic Code Triggered Record function.This function works automatically and does not appear as an option on any menu. If a diagnostic fault occurs while you are testing a vehicle, the software automatically creates a recording for playback and alerts you with a screen message. To replay these recordings, refer to “Play- back a Data File” on page 21.

Basic Datastream Procedure

Use the following steps to obtain a basic understanding of how the Datastream function works.

tions in “Chapter 2: Start-up Steps” on page 13.
