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) 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.

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) 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 / Active Test.

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

Engine and ECT

Tester Display	Test Part	Control Range	Diagnostic Note
Connect the TC and TE1	Connects and disconnects TC and TE1. (changes to the fluid temperature detection mode)	ON/OFF	[Vehicle Condition] Ignition switch ON Vehicle stopped
Activate the Solenoid (SLU)	Operates shift solenoid valve SLU	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SLT)*	Operates shift solenoid valve SLT to raise the line pressure.	ON/OFF HINT: ON: No action (normal operation) OFF: Line pressure up (When the Active Test of "Activate the Solenoid (SLT)" is performed, the ECM commands the shift solenoid valve SLT to turn off).	[Vehicle Condition] Vehicle Stopped Engine idling
Activate the Lock Up	Controls the shift solenoid valves SLU and SL to set the automatic transmission to the lock-up condition.	ON/OFF	Can be used to check shift solenoid valves SLU and SL operation. [Vehicle Condition] Vehicle speed: 60 km/h (36 mph) or more
Activate the Solenoid (SL)	Operates shift solenoid valve SL	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Control the Shift Position	Operates the shift solenoid valves to allow gears to be selected manually.	Press "→" button: Up-shift occurs Press "←" button: Down-shift occurs	Can be used to check the operation of the shift solenoid valves. Up-shifts and down-shifts should be performed consecutively. A 10 second interval is required between gear changes. Do not down-shift at high speeds. Doing so will damage the automatic transmission. [Vehicle Condition] 50 km/h (31 mph) or less
Activate the Solenoid (SL1)	Operates shift solenoid valve SL1	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL2)	Operates shift solenoid valve SL2	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL3)	Operates shift solenoid valve SL3	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL4)	Operates shift solenoid valve SL4	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N

*: The "Activate the Solenoid (SLT)" Active Test is performed to allow confirmation that the line pressure changes. The line pressure changes are confirmed using the same SST that is used for the Hydraulic Test (See page HINT: ).

HINT:

Note that the pressure readings for the Active Test and Hydraulic Test are different.
