DATA LIST / ACTIVE TEST

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) Warm up the engine.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Engine and ECT / Data List.

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

HINT:

Normal Condition: If no idling conditions are specified, the shift lever should be in N or P, and the A/C and all accessory switches should be off.

Powertrain > Engine and ECT > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
Battery Voltage	Battery voltage	Min.: 0.000 V Max.: 65.535 V	11 to 14 V (Idling)	If the result is not as specified, abnormal battery voltage is suspected.
Alternator Output Duty	Generator output duty	Min.: 0.0% Max.: 399.9%	Changes according to alternator output	If the result is not as specified, a malfunction of the charging system is suspected.
Alt Vol - Non Active Test	Requested voltage when regulator forced drive is not executed	Min.: 0.000 V Max.: 79.998 V	13.5 to 14.4 V (After engine start (Varies with battery temperature or driving conditions))	If the result is not as specified, a malfunction of the charging system is suspected.
Alt Vol - Active Test	Request voltage when regulator under forced activation	Min.: 0.000 V Max.: 79.998 V	10.6 to 16 V (After engine start (Request instruction voltage value))	If the result is not as specified, a malfunction of the charging system is suspected.
Previous Trip Alternator Max Output Time	Generator maximum generating time during previous drive	Min.: 0 sec. Max.: 65535 sec.	-	-
Initial Engine Battery Minimum Voltage	Minimum battery voltage at engine start	Min.: 0.0 V Max.: 25.5 V	-	-

HINT:

Normal Condition: If no idling conditions are specified, the shift lever should be in N or P, and the A/C switch and all accessory switches should be off.

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 ignition switch to ON.

(d) Enter the following menus: Powertrain / Engine and ECT / Active Test.

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

Powertrain > Engine and ECT > Active Test

Tester Display	Measurement Item	Control Range	Diagnostic Note
Control the Voltage of Alternator	Requested output voltage of generator regulator during forced activation	Between 10.6 and 16.0 V	Test is possible after engine start
