INSPECTION PROCEDURE

УКАЗАНИЕ:
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 (ACCELERATOR POSITION)


    A00944SE37

  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 / Accel Position.

  1. Check that the value displayed on the intelligent tester changes when repeatedly depressing and releasing the accelerator pedal.

    OK:
    Value changes.

2.CHECK HARNESS AND CONNECTOR (ECM - ACCELERATOR PEDAL POSITION SENSOR)

  1. Disconnect the accelerator pedal position sensor connector.

  1. Disconnect the ECM connector.

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