INSPECTION PROCEDURE

УКАЗАНИЕ:
  1. If DTCs related to different systems that have terminal E2 as the ground terminal are stored simultaneously, there may be an open circuit between terminal E2 and body ground.
  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.


When using intelligent tester:

1.READ VALUE USING INTELLIGENT TESTER (INTAKE MANIFOLD PRESSURE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / PIM.

    OK:
    Value is same as atmospheric pressure.

    УКАЗАНИЕ:
    When DTC 35 is stored, the type of malfunction can be determined based on the manifold absolute pressure (see below).

    Intake Manifold Pressure (kPa)
    		Malfunction
    Approx. 0
    1. Short in PIM circuit
    192 or more
    1. Open or short in VC circuit
    2. Open in PIM circuit
    3. Open in E2 circuit

2.CHECK CONNECTION OF VACUUM HOSE

  1. Check that the vacuum hose is securely connected and that there are no leaks from the connection.

    OK:
    The vacuum hose is securely connected and there are no leaks from the connection.



NG
REPAIR OR REPLACE VACUUM HOSE
OK
