Data List/Active Test

HINT:

Using the Techstream to read the Data List allows 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 engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: All ECUs/(desired system)/Data List.
5. Check the values by referring to the table below.

HINT:

Using the Techstream to perform Active Test allows relays, VSVs, actuators and 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 the Techstream to the DLC3.
2. Turn the engine switch to on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical/(desired system)/Active Test/All.
5. Perform the Active Test by referring to the table below.
