Data List / Active Test

HINT:

Using Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

1. Connect Techstream to the DLC3.
2. Turn the ignition switch ON and turn Techstream ON.
3. Read the DATA LIST by following the prompts on the tester.

HINT:

Using Techstream to perform Active Tests allows the relay, actuator, and other items to operate without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Test early in troubleshooting is one way to save diagnostic time. Data List information can be display while performing Active Test.

1. Connect Techstream to the DLC3.
2. Turn the ignition switch ON and turn Techstream ON.
3. Perform the ACTIVE TEST by following the prompts on the tester.
