INSPECTION PROCEDURE


DATA LIST
HINT:
According to the Data List displayed on the intelligent tester, you can read the value of switches, sensors, actuators and other items without removing any parts. Reading the Data List as the first step in troubleshooting is one method to save labor time.
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.

  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 on the tester.

  6. Enter the following items: "Powertrain / ECT / Data List".

  7. According to the display on the tester, read "Data List".

    		Shift lever position is;
    R: ON
    Except R: 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.
    Shift SW Status (P Range)
    		PNP Switch Status/
    ON or OFF
    		Shift lever position is;
    P: ON
    Except P: 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.
    Shift SW Status (N Range)
    		PNP Switch Status/
    ON or OFF
    		Shift lever position is;
    N: ON
    Except 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.
    Shift SW Status (D Range)

    Standard resistance:
    Shift Position
    		Tester Connection
    		Specified Condition
    P
    		1 - 3 and 4 - 9
    		Below 1 Ω
    Except P
    		10 kΩ or higher
    R
    		1 - 2
    		Below 1 Ω
    Except R
    		10 kΩ or higher
    N
    		1 - 8 and 4 - 9
    		Below 1 Ω
    Except N
    		10 kΩ or higher
