ECU Part Number

This is the main window of the NDSIII software which shows the ECM Nissan Identification part number. The VIN number is also displayed if available.

Basic and Advance Functions can be selected by clicking on the buttons, using the shortcut keys (F1 - F12) or using the Menu bar. Most functions except for Data Replay and Log Analyser are disabled until communication with the ECU is established.

At the bottom of the window, next to the temperature and speed units, we can see which type of wide band O2 sensor was identified by the software.

The progress bar indicates communication between the ECU and PC. If the bar is not moving, the data is not being received from the ECU.

Data Display ECM

Classic design gauges

Modern design gauges

Data Display window uses 12 gauges and 9 registers to display real time information about the engine as measured or calculated by the engine ECU. Parameters are assigned to gauges in the Data Display Settings window.

Data Display Settings

This window is used to assign parameters and registeres to be displayed by the Data Display function. Only parameters and registers that are supported by the currently connected ECU are available for selection. Gauges are counted from left to right, top to bottom.

Work Support ECM Diesel

Work Support functions allow users to perform common advance service procedures. Those procedures may need to be performed after replacement parts are installed.

Config Clear - Initializes the ASCD application status.

DPF Data Clear - Should only be performed when DPF is replaced. Based on the signal from sensors ECM estimates the amount of particulate matter in diesel particulate filter and stores the value in EEPROM as diesel particulate filter data. When oxidation catalyst with diesel particulate filter is replaced with a new one, there is a difference between diesel particulate filter data stored in ECM and the actual amount of particulate matter in diesel particulate filter, because no particulate matter is trapped in new diesel particulate filter. In this case, ECM cannot perform regeneration control correctly. Do not perform this function if DPF is not replaced with a new one. Diesel particulate filter may be damaged because regeneration is not performed at appropriate timing.

Pump Leant Clear - In order to always keep optimum fuel pressure in fuel rail, the ECM controls fuel pump in high precision with monitoring the signal of fuel rail pressure sensor. Accordingly, the ECM always learns characteristic value of fuel pump. Fuel Pump Learning Value Clearing is an operation to clear the value of the fuel pump learning.

EGR Valve Learn Clear - EGR volume control valve closed position learning value should be cleared when EGR volume control valve is removed or replaced.

Injector Adjustment Value Clear - Initilaizes injector adjustment value stored in ECM.

Fuel injection quantity learning is performed to adjust fuel injection quantity deviated during the use of injectors under various conditions to properly adjust the injection quantity. If this learning is not performed, then malfunctions, such as knocking and poor acceleration may occur.

 

Injector Registration ECM Diesel

Injector adjustment Value Registration function allows users to display the current injector registration values and update them if needed.

The injector adjustment value which is correctly stored in ECM is needed for precise fuel injection control. A performance of emission control and a drivability may effect when there is a mismatch.
