Data List / Active List
2GR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: DATA LIST / ACTIVE TEST
1. DATA LIST
HINT
Reading the Data List displayed on the Techstream enables values, including those of the switches, sensors, and actuators, to be checked without removing any parts. Reading the Data List as the first step in troubleshooting is one method to shorten diagnostic time.
NOTICE:
In the table below, the values listed under Normal Condition are for reference only. Do not depend solely on these values when determining whether or not a part is faulty.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Start the engine.
(e) Turn the tester on.
(f) Select the following menu items: Powertrain / Engine and ECT / Data List.
(g) Check the values by referring to the table below.
Normal condition: If no idling conditions are specified, the transmission gear selector lever should be in the N or P position, and the A/C switch and all accessory switches should be OFF.
*1: USA, Canada
*2: Values are only displayed when performing the Active Test: Control the VVT Linear (Bank 1 or Bank 2) or Control the VVT Exhaust Linear (Bank 1 or Bank 2). For other Active Tests, the value will be 0.
*3: Excluding throttle valve opening percentage due to Idle Speed Control (ISC).
2. ACTIVE TEST
HINT
Performing an Active Test enables components including the relays, vacuum switching valve, and actuators, to be operated without removing any parts. The Active Test can be performed with the Techstream. Performing an Active Test in the first step in troubleshooting is one method to shorten diagnostic time.
Data List can be displayed during Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the tester on.
(d) Select the following menu items: Powertrain / Engine and ECT / Active Test.
(e) Perform the Active Test by referring to the table below.
NOTICE:
* *1: If the display of the Data List's Catalyst OT MF F/C item is Not Avl, perform this Active Test with the vehicle stopped and the engine idling.
* *1: If the display of the Data List's Catalyst OT MF F/C item is Avail, perform this Active Test as described below.
(1) Stop the engine and turn the ignition switch on (IG) to turn #1 Fuel Cut (to #6 Fuel Cut) ON.
(2) Start the engine.
HINT
*2: When cranking the engine, each cylinder measures the engine speed.
In this Active Test, the fuel and ignition of all cylinders is cut and cranking occurs for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders.
Warm up the engine.
Turn the ignition switch off.
Connect the Techstream to the DLC3.
Turn the ignition switch on (IG).
Turn the tester on.
Enter the following menus: Powertrain / Engine / Active Test / Check the Cylinder Compression.
HINT
* To display the entire Data List, press the pull down menu button next to Primary. Then select Compression.
* Push the Function button and then select Snapshot Configuration to set the Trigger Point to zero.
* Set the Record Time to 30 seconds.
Push the snapshot button to turn the snapshot function on.
HINT
Using the snapshot function, data can be recorded during the Active Test.
While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.
HINT
After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode.
Fully open the throttle.
Crank the engine for about 10 seconds.
HINT
Continue to crank the engine until the values change from the default value (51199 rpm).
Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the tester.
NOTICE:
* Do not crank the engine continuously for 20 seconds or more.
* If Check the Cylinder Compression needs to be performed after it is turned ON and performed once, press Exit button to return to the Active Test menu screen. Then perform Check the Cylinder Compression again.
* Use a fully-charged battery.
HINT
At first, the tester displays extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, each cylinder engine speed measurement will change to the actual engine speed.
Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops.
NOTICE:
If the Active Test is changed to OFF while the engine is being cranked, the engine will start.
Push the snapshot button to turn the snapshot function off.
Enter the following menus: Function / Snapshot Review / Engine / Snapshot File Manager, select the recorded data and display the data.
HINT
If the data is not displayed, the change of the values cannot be observed.
Check the change in engine speed values.
HINT
As the data values of the Active Test return to their default values when cranking is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during cranking.
3. SYSTEM CHECK
HINT
Performing a System Check enables the system, which consists of the multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are set, and can detect potential malfunctions in the system. The System Check can be performed with the Techstream.
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the tester on.
(d) Select the following menu items: Powertrain / Engine and ECT / Utility.
(e) Perform the System Check by referring to the table below.
