ECU Part Number

This is the main window of the NDSII software which shows the ECM Nissan Identification part number. Basic and Advance Functions can be selected by clicking on the buttons, using the shortcut keys (F1 - F11) or using the Menu bar. Most functions except Data Replay and Log Analyser are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates communication between the ECU and PC. If the bar is not moving there is no data 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 a 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 to be displayed by the Data Display function. Only parameters that are supported by the currently connected ECU are available for selection. Gauges are counted from left to right, top to bottom. Multiple gauges can monitor the same parameter.

Below is a video of Data Display function in use.

 

Data Logging ECM

Selected parameters can be logged to a file. This function can also be accessed from the Data Display window. The data log file can be analysed using the Data Replay or Log Analyser functions.

Below is a video of Data Logging function in use.

 

Self Diagnostics ECM

Self Diagnostics function allows users to read and reset engine ECU error codes.

Below is a video of Self Diagnostic function in use.

 

Idle Adjustment

Idle Adjustment function allows users to adjust the base idle RPM. The setting is saved to the ECU and it does not reset with engine restart.

Below is a video of the Idle Adjustment function in use.

 

Timing Adjustment

Timing Adjustment function allows users to adjust the base ignition timing. The setting is saved to the ECU and it does not reset with engine restart.

Below is a video of the Timing Adjustment function in use.

 

Active Test ECM

Active Test allows users to temporary modify some of the engine parameters for testing purposes. They return to their original values when a function is stopped, PC disconnected or engine restarted.

Note: It is possible to damage the engine if the A/F Base % functions is used to excessively modify fuel delivery. Likewise the engine may overheat if the Engine Temperature is set to low for a long period of time. Do not use those functions if you are not sure how they will effect your engine.

Below is a video of Active Test function in use.

 

Work Support

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

Clear Self Learn - clears the A/F Base SL map learned by the ECU.

Idle Air Volume Learn - is an operation to learn the fully closed position of the throttle valve.

 

Program Immobiliser Key - allows to register the Nissan transponder keys with the Immobiliser Note: The immobiliser security PIN CODE needs to be known. Initially all registered keys will be erased and all keys will need to be reregistered.

 

Cylinder Power Test

Cylinder Power Test function can be used to identify cylinder that is under performing. This function allows shutting down individual cylinders. If all of the cylinders are producing the same amount of power the engine RPMs will drop exactly the same amount on each cylinder that is cancelled.

Below is a video of Cylinder Power Test function in use.

 

Log Analyser

Classic design

Modern design

Log Analyser is used to review log files previously generated by with Data Logging function. Graphs are drawn by selecting boxes next to parameter value. Graph colours match the parameter value colours.

Speed Test

Speed Test is a unique function for measuring car's acceleration performance. Predefined or user specific tests can be used. Due to the low resolution of Nissan speed sensors, measurements should only be used as a guide and not a true reflection of car's performance.

Note: This function should not be used while driving on public roads.

Data Replay

Classic design gauges

Modern design gauges

Data Replay allows users to replay previously saved data logs. Replay can be speeded up or slowed down using the Replay speed scroll bar. The Position scroll bar moves the currently diplayed record up and down the log file.

Address Watch

Address Watch function is used for monitor specific ECU memory addresses. By monitoring a memory address extra information can be retrieved that is not normally available using Consult II protocol. A knock sensor reading can be obtain using this method if knock sensor memory address is known.

Wideband O2 sensor

Nissan DataScan II also supports wideband Air/Fuel ratio meters from Innovate Motorsports. A second serial port is used to connect to the controller and collect data.

The data from the wideband meter can be displayed or logged in conjunction with other engine parameters using the Data Logging function.

ECU Part Number BCM

The BCM tab shows the BCM Nissan Identification part number. Basic Functions can be selected by clicking on the buttons or using the Menu bar. All functions are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

Note: Some vehicles may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. This software does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol.

Self Diagnostics BCM

Self Diagnostics function allows users to read and reset BCM error codes.

Active Test BCM

Active Test allows users to temporally activate some of the functions of the BCM. This is usually used to manually test the functionality of the systems controlled by the BCM.

Note: Functions not supported by the BCM are disabled (grayed out).

ECU Part Number TCM

The TCM tab shows the TCM Nissan Identification part number. Basic Functions can be selected by clicking on the buttons or using the Menu bar. Most functions except Data Replay and Log Analyser are disabled until communication with the ECU is successfully established.

Progress bar at the bottom indicates data being send between the ECU and PC. If the bar is not moving there is no data being received from the ECU.

Note: Some vehicles may use K line for diagnostics of engine ECU (ECM) but still use DDL1 line for diagnostics of other control modules. This software does not support diagnostics over the DDL1 line. Some of those models are: X-trail, Maxima, Patrol.
