Data List / Active Test [11/2018 - 12/2021]

HINT: 

Using the 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 the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Pre-Collision System / Data List.
5. Read the Data List according to the display on the Techstream.

   Body Electrical > Pre-Collision System > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated 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 Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Pre-Collision System / Active Test.
5. Perform the Active Test according to the display on the Techstream.

   Body Electrical > Pre-Collision System > Active Test 

   Tester Display	Measurement Item	Control Range	Diagnostic Note
   PCS Warning Buzzer	Sounds the meter buzzer	Active / Not Active	Test possible with ignition switch ON, vehicle stopped
