Automatic Transmission System (For 1Gd-Ftv) -- Data List / Active Test



DATA LIST
HINT:
Using the GTS 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.

  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the GTS to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the GTS on.

  6. Enter the following menus: Powertrain / Engine and ECT / Data List.

  7. According to the display on the GTS, read the Data List.

ACTIVE TEST
HINT:
Using the GTS 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.

  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the GTS to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the GTS on.

  6. Enter the following menus: Powertrain / Engine and ECT / Active Test.

  7. According to the display on the GTS, perform the Active Test.

    		Connects and disconnects TC and TE1.
    (changes to the fluid temperature detection mode)
    		ON/OFF
    		[Vehicle Condition]
    1. Engine switch on (IG)
    2. Vehicle stopped
    Activate the Solenoid (SLU)
    		Operates shift solenoid valve SLU
    		ON/OFF
    		[Vehicle Condition]
    1. Engine switch on (IG)
    2. Engine stopped
    3. 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]
    1. Vehicle Stopped
    2. 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]
    1. Throttle valve opening angle: Less than 25%
    2. Vehicle speed: 80 km/h (50 mph) or more
    Activate the Solenoid (SL)
    		Operates shift solenoid valve SL
    		ON/OFF
    		[Vehicle Condition]
    1. Engine switch on (IG)
    2. Engine stopped
    3. Shift lever in P or N
    Control the Shift Position
    		Operates the shift solenoid valves to allow gears to be selected manually.
    1. Press "→" button: Up-shift occurs
    2. 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]
    1. 50 km/h (31 mph) or less
    Activate the Solenoid (SL1)
    		Operates shift solenoid valve SL1
    		ON/OFF

    1. Engine switch on (IG)
    2. Engine stopped
    3. 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 (LandCruiser RM000000W7B0TLX.html).

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