DESCRIPTION

The ECM opens and closes the throttle valve using a DC motor type actuator. With the throttle valve, the exhaust gas recirculation volume can be properly controlled by opening and closing the valve. Also, engine vibration and noise will be reduced by closing the valve when the engine is stopped.

INSPECTION PROCEDURE

NOTICE:
When replacing the ECM, the ECM needs Registration and Initialization (Click here).

HINT:
  1. When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the intelligent tester. Then after installing the new ECM, perform all of the initializations/registrations for the "Learning Values Write" function by following the instructions shown on the tester display.
  2. Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (DIESEL THROTTLE TARGET ANGLE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Diesel Throttle Target Angle.

  1. When changing the Active Test value from 0 to 90%, check that Actual Throttle Position smoothly changes to the set opening angle.

OK:
Value smoothly changes to the set opening angle.

2.CHECK HARNESS AND CONNECTOR (DIESEL THROTTLE BODY ASSEMBLY - ECM)


    A199035E03

  1. Disconnect the diesel throttle body assembly connector.

  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance (Check for Open):
    Tester Connection
    		Condition
    		Specified Condition
    A19-43 (M+) - B37-2 (M+)
    		Always
    		Below 1 Ω
    A19-42 (M-) - B37-1 (M-)
    		Always
    		Below 1 Ω

    Standard Resistance (Check for Short):
    Tester Connection
    		Condition
    		Specified Condition
    A19-43 (M+) or B37-2 (M+) - Body ground
    		Always
    		10 kΩ or higher
    A19-42 (M-) or B37-1 (M-) - Body ground
    		Always
    		10 kΩ or higher

3.INSPECT DIESEL THROTTLE BODY ASSEMBLY


    A208565E01

  1. Remove the diesel throttle body assembly connector.

  1. Measure the resistance according to the value(s) in the table below when you move the throttle valve using your finger.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    2 (M+) - 1 (M-)
    		20°C (68°F)
    		0.3 to 100 Ω
