Data List / Active Test

  1. DATA LIST 

    HINT:

    According to the DATA LIST displayed by the intelligent tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time.

    NOTE: 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 ignition switch off.
    3. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
    4. Turn the ignition switch to the on position.
    5. Turn on the tester.
    6. Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
    7. According to the display on the tester, read the "DATA LIST".
      DATA LIST REFERENCE

      Item Measurement Item/Range (display) Normal Condition Diagnostic Note
      STOP LIGHT SW Stop light switch Status/ON or OFF
      • Brake Pedal is depressed: ON
      • Brake Pedal is released: OFF
      		 -
      PNP SW [NSW] PNP switch Status/ON or OFF Shift lever position is;
      P and N: ON
      Except P and N: OFF      		 When the shift lever position displayed on the Intelligent tester differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.
      HINT:
      When the failure still occurs even after adjusting these parts, See FAIL-SAFE CHART 
      REVERSE PNP switch Status/ON or OFF Shift lever position is;
      R: ON
      Except R: OFF
      DRIVE PNP switch Status/ON or OFF Shift lever position is;
      D and S: ON
      Except D and S: OFF
      SHIFT Actual Gear Position/1st, 2nd, 3rd, 4th or 5th Shift Lever Position is;
      • D: 1st, 2nd, 3rd, 4th or 5th
      • S: 1st, 2nd, 3rd, 4th or 5th
      		 -
      LOCK UP SOL Lock Up Solenoid Status/ON or OFF
      • Lock Up: ON
      • Except Lock Up: OFF
      		 -
      SOLENOID (SLT) Shift Solenoid SLT Status/ON or OFF
      • Accelerator pedal is depressed: OFF
      • Accelerator pedal is released: ON
      		 -
      AT FLUID TEMP ATF Temp. Sensor Value/min.: -40°C (-40°F)
      max.: 215°C (419°F)
      • After Stall Test;

        Approx. 80°C (176°F)

      • Equal to ambient temperature when cold soak
      		 If the value is "-40°C (-40°F)" or "215°C (419°F)", ATF temp. sensor circuit is opened or shorted.
      SPD (NC) Counter Gear Speed/display: 50 r/min HINT:
      3rd when shift lever position is D position (After warming up the engine);
      • Intermediate shaft speed (NC) becomes close to the engine speed.
      		 -
  2. ACTIVE TEST 

    HINT:

    Performing the ACTIVE TEST using the intelligent tester allows the relay, VSV, actuator and so on to operate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method to shorten labor time.

    It is possible to display the DATA LIST during the ACTIVE TEST.

    1. Warm up the engine.
    2. Turn the ignition switch off.
    3. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
    4. Turn the ignition switch to the ON position.
    5. Push the "ON" button of the intelligent tester.
    6. Select the item "DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST".
    7. According to the display on tester, perform the "ACTIVE TEST".
      ACTIVE TEST REFERENCE

      Item Test Details Diagnostic Note
      SHIFT [Test Details]
      Operate the shift solenoid valve and set the each shift position by yourself.
      [Vehicle Condition]
      • IDL: ON
      • Less than 50 km/h (31 mph)

      [Others]
      • Press "-->" button: Shift up
      • Press "<--" button: Shift down
      		 Possible to check the operation of the shift solenoid valves.
      LOCK UP [Test Details]
      Control the shift solenoid DSL to set the automatic transaxle to the lock-up condition.
      [Vehicle Condition]
      • Vehicle Speed: 60 km/h (37 mph) or more, and 6th gear
      		 Possible to check the DSL operation.
      LINE PRESS UP(1) [Test Details]
      Operate the shift solenoid SLT and raise the line pressure.
      [Vehicle Condition]
      • Vehicle Stopped.
      • IDL: ON

      HINT:
      OFF: Line pressure up (When the active test of "LINE PRESS UP" is performed, the ECM commands the SLT solenoid to turn off). ON: No action (normal operation)      		 -
      (1) "LINE PRESS UP" in the ACTIVE TEST is performed to check the line pressure changes by connecting the SST to the automatic transaxle, which is used in the HYDRAULIC TEST (See HYDRAULIC TEST ) as well.

      HINT:

      The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
