U760E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: DATA LIST / ACTIVE TEST
1. DATA LIST
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.
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.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
HINT
* To display the list box, press the pull down menu button next to Primary. Then select a measurement group.
* When you select a measurement group, the ECU data belonging to that group is displayed.
* Measurement Group List / Description
* All Data / All data
* Primary / -
* Engine Control / Engine control system related data
* Gas General / -
* Gas AF Control / Air fuel ratio control system related data
* Gas AF O2 Sensor / Air fuel ratio sensor and heated oxygen sensor related data
* Gas Throttle / Gasoline throttle system related data
* Gas Intake Control / Intake control system related data
* Gas Valve Control / Valve control system related data
* Gas Misfire / "Misfire" related data
* Gas Starting / "Difficult to start" related data
* Gas Rough Idle / "Rough idle" related data
* Gas Evaporative / Evaporative system related data
* Gas CAT Converter / Catalyst converter related data
* Check Mode / Check mode related data
* Monitor Status / Monitor status related data
* Ignition / Ignition system related data
* Charging Control / Charging control system related data
* Compression / Data used during "Check the Cylinder Compression" Active Test
* AT / Automatic transmission system related data
* Vehicle Information / Vehicle information
(g) According to the display on the Techstream, read the Data List.
HINT
* The title used for each group of Data List items in this repair information does not appear on the Techstream. However, the name in parentheses after the title, which is a Measurement Group, does appear on the Techstream. When the name shown in parentheses is selected on the Techstream, all the Data List items listed for that group will be displayed.
* "Result of real-vehicle check" is the assessment of one vehicle. Use it only for reference.
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.
(c) Connect the Techstream to the DLC3.
(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.
*: 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 Hydraulic Test.
HINT
Note that the pressure readings for the Active Test and Hydraulic Test are different.
