Data List / Active Test

WARNING: This page is about a different variant/trim than selected.
  1. DATA LIST 

    HINT:

    By reading the DATA LIST displayed on an intelligent tester, 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.

    NOTE: 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.
    1. Warm up the engine.
    2. Turn the ignition switch OFF.
    3. Connect the intelligent tester to the DLC3.
    4. Turn the ignition switch ON.
    5. Turn the tester ON.
    6. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
    7. 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: DATA LIST values are only displayed when performing the following ACTIVE TEST: VVT B1. For other ACTIVE TESTs, the DATA LIST value will be 0.
  2. ACTIVE TEST 

    HINT:

    Performing an ACTIVE TEST enables components including the relays, VSV (Vacuum Switching Valve) and actuators, to be operated without removing any parts. The ACTIVE TEST can be performed with the intelligent tester. Performing the ACTIVE TEST as the first step of troubleshooting is one method of shortening diagnostic time. DATA LIST can be displayed during ACTIVE TEST.

    1. Connect the intelligent tester to the DLC3.

    COMPRESS CHECK All cylinder injector fuel cut and ignition stop ON/OFF *
    HINT:
    *: When cranking the engine, each cylinder measures the engine rpm.

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

    1. Warm up the engine.
    2. Turn the ignition switch OFF.
    3. Connect the intelligent tester to the DLC3.
    4. Turn the ignition switch ON and turn the intelligent tester ON.
    5. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / COMPRESS CHECK.

      HINT:

      If the results are not displayed normally, select the display items from the DATA LIST before performing the ACTIVE TEST. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / USER DATA / ENG SPEED #1 and ENG SPEED #2, ENG SPEED #3, ENG SPEED #4 (Press the YES button to change the ENG SPEED #1 to #4 is YES) and then press the ENTER button.

    6. While the engine is not running, press the RIGHT or LEFT button to change the COMPRESS CHECK to ON.

      HINT:

      After performing the above procedure, the ACTIVE TEST'S COMPRESS CHECK will start. Fuel injection for all cylinders is prohibited, and the each cylinder's engine rpm measurement will enter standby.

    7. Fully open the throttle.
    8. Crank the engine for about 10 seconds.
    9. Monitor the engine speed (ENG SPEED #1 to #4) displayed on the tester.

      HINT:

      At first, the tester's display will show each cylinder's engine rpm measurement to be extremely high. After approximately 10 seconds of engine cranking, each cylinder's engine rpm measurement will change to the actual engine rpm.

    NOTE:
    • After the ACTIVE TEST'S COMPRESS CHECK is turned ON, it will automatically turn off after 255 seconds.
    • When the COMPRESS CHECK test is OFF and the engine is cranked, the engine will start.
    • If the COMPRESS CHECK 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 COMPRESS CHECK test again.
    • Use a fully-charged battery.
  3. SYSTEM CHECK 

    HINT:

    Performing a 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 SYSTEM CHECK can be performed with the intelligent tester.

    1. Connect the intelligent tester to the DLC3.
    2. Turn the ignition switch ON.
    3. Turn the tester ON.
    4. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK.
    5. Perform the SYSTEM CHECK by referring to the table below.
