LIGHTING: LIGHTING SYSTEM: DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: Using Techstream to read the Data List allows the values or states of switches, sensors, actuator 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.
CAUTION:
In the following table, 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 Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn Techstream on.
(d) Select the following menu items: Body Electrical / (desired system) / Data List.
(e) Read the Data List according to the display on Techstream.

2. PERFORM ACTIVE TEST
HINT: Using 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 Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn Techstream on.
(d) Select the following menu items: Body Electrical / (desired system) / Active Test.
(e) Perform the Active Test according to the display on Techstream.
