Data List / Active List

2GR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: DATA LIST / ACTIVE TEST

1. DATA LIST

HINT
By reading the Data List displayed on the Techstream, values can be checked, including those of the switches, sensors, and actuators, without removing any parts. Reading the Data List as the first step of troubleshooting is one method of shortening 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) Turn the ignition switch to ON.

(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.

















































HINT
* *1: 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.
* *2: Excluding throttle valve opening percentage due to Idle Speed Control (ISC).
2. ACTIVE TEST

HINT
Performing the Active Test enables components including the relays, VSVs (Vacuum Switching Valves) and actuators, to be operated without removing any parts. The Active Test can be performed with the Techstream. Performing the Active Test as the first step of troubleshooting is one method of shortening diagnostic time.

* The Data List can be displayed during the Active Test.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(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.
* Stop the engine and turn the ignition switch to ON to turn Control the Cylinder #1 Fuel Cut (to Control the Cylinder #6 Fuel Cut) ON.
* Start the engine.
HINT
*2: When cranking the engine, each cylinder measures the engine speed.

In this Active Test, the fuel injection and ignition of all cylinders is cut, and cranking occurs for approximately 10 seconds. Then, each cylinder measures the engine speed. If a cylinder engine speed is higher than the others, that cylinder compression pressure is compared to the others, and whether or not the compression pressure is low can be determined.

* Warm up the engine.

* Turn the ignition switch off.

* Connect the Techstream to the DLC3.

* Turn the ignition switch to ON.

* Turn the Techstream 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.

* While the engine is not running, press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON.

HINT
After performing the above procedure, the Active Test Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited, and each cylinder engine speed measurement will enter standby.

* Fully open the throttle valve.

* Crank the engine for approximately 10 seconds.

* Monitor the engine speed (Engine Speed of Cyl #1 to #6) displayed on the Techstream.

HINT
At first, the Techstream 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.

NOTICE:
* When the Check the Cylinder Compression test is OFF and the engine is cranked, the engine will start.
* If the Check the Cylinder Compression test needs to be performed after it is turned on and performed once, press Exit to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again.
* Use a fully-charged battery.
3. SYSTEM CHECK

HINT
Performing an Evaporative System Check enables the system, which consists of 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 Evaporative System Check can be performed with the Techstream.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the tester ON.

(d) Select the following menu items: Powertrain / Engine and ECT / Utility.

(e) Perform the Evaporative System Check by referring to the table below.
