Scan Tool Testing and Procedures

METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: DATA LIST / ACTIVE TEST

1. DATA LIST

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.

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 engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical, Powertrain or Chassis / (desired system) / Data List.

(e) According to the display on the Techstream, read the Data List.

2. ACTIVE TEST

HINT
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.

(a) Connect the Techstream to the DLC3.

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

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / (Combination Meter) / Active Test.

(e) According to the display on the Techstream, perform the Active Test.

*1:

* The doors will be locked automatically when performing the speedometer Active Test. This is a normal function.
* The displayed value has the same units (km/h, mph) as the main scale of the vehicle speedometer.
* The needle position should be within the acceptable range.
*2: If this Active Test is being performed and the engine switch is turned off and then on (IG), the A/T and ODO/TRIP display background may turn white. If this occurs, end this Active Test and turn the engine switch off.
