Scan Tool Testing and Procedures

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

1. DATA LIST

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) Warm up the engine.

(b) Turn the power switch off.

(c) Connect the Techstream to the DLC3.

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

(e) Turn the Techstream on.

(f) Enter the following menus:

(1) for Combination Meter: Body Electrical / Combination Meter / Data List.

(2) for ABS/VSC/TRAC: Chassis / ABS/VSC/TRAC / Data List.

(3) for Engine and ECT: Powertrain / Engine and ECT / Data List.

(4) for Hybrid Control: Powertrain / Hybrid Control / Data List.

(5) for Main Body: Powertrain / Main Body / Data List.

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

2. ACTIVE TEST

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 power switch on (IG).

(c) Turn the Techstream on.

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

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

Combination Meter





* *1: with mph units

* *2: with km/h units

* *3: w/ Rear Fog Light

* *4: w/ Pre-collision

* *5: w/ Tire Pressure Warning System

* *6: w/ Intuitive Parking Assist System

* *7: w/ Dynamic Radar Cruise Control System

* *8: Indicator or warning light does not operate when the mode has been disabled via customization.
