Scan Tool Testing and Procedures

CRUISE CONTROL: LANE-KEEPING ASSIST SYSTEM: DATA LIST / ACTIVE TEST

1. DATA LIST

HINT
Using the Techstream to read the Data List allows values or status 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.

NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Using the Techstream, enter the following menus:

(1) Select: All ECUs / (desired menu) / Data List /

(e) Check the values by referring to the table below.

2. ACTIVE TEST

HINT
Using the Techstream to perform Active Test 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 Test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Test.

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Using the Techstream, enter the following menus:

(1) Select: All ECUs / (desired menu) / Active Test /

(e) Perform the Active Test by referring to the table below.
