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.

   When using Techstream with the engine switch off, turn on and off any of the door courtesy light switches repeatedly at 1.5 or less second intervals until communication between the tester and vehicle starts.

2. Turn the engine switch on (IG).
3. Read the DATA LIST.

HINT: 

Using Techstream to perform ACTIVE TEST allows the 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 the ACTIVE TEST early in troubleshooting is one way to save diagnostic time. The DATA LIST can be displayed while performing ACTIVE TESTs.

1. Connect Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Perform the ACTIVE TEST according to the display on the tester.
