Below are all the functions it provides:

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 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.

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.

Self Diagnostics ECM

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

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.

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.

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.

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.

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.

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.

Data Logging TCM

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

Self Diagnostics TCM

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

ECU Part Number ABS

The ABS tab shows the ABS 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.

Data Logging ABS

Self Diagnostics ABS

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

Work Support ABS

Work Support functions allow users to perform advance service procedures. Those procedures may need to be performed after replacing parts.

OBDII Monitor Status

OBDII Monitor Status shows the current status of various monitoring systems used by the car’s engine management system.

OBDII Log Analyser

OBDII Fuel System Satus

OBDII Fuel System Status can be used to check if the car’s fuel system is running in Closed Loop mode.

Fuel systems do not normally refer to injector banks. They are intended to represent completely different fuel systems that can independently enter and exit closed loop fuel. Banks of injectors on a V-engine are generally not independent and share the same closed-loop enablement criteria.

OBDII Data Logging

Selected OBDII parameters can be logged to a file. The data log file can then be analysed using the Log Analyser function.

Due to the slow nature of OBDII protocol it’s recommended to log only the required parameters.

How to Install RedLineGoods Automatic Transmission Shift Boot on 2002-2004 Nissan Maxima

Credit: redlinegoods

To install on an automatic, you need to wedge the shift boot between the shifter assembly and the trim piece surrounding it. Therefore it is necessary to remove that surrounding trim.

When removing the trim piece surrounding the shifter, hazard switch and power outlet, the thing to be cautious about is the shifter trim (the silver piece with the gear labels). If you hit the front of that with the underside of the trim piece you are removing, it may get scratched.

Take time & care when doing this, and you should be OK. If you’re really concerned about it, you can put tape or something over the edge of the silver piece first to avoid scratching it. Now, take a very small flathead screwdriver (as in a glasses repair kit) and wrap the tip in an old t-shirt or rag. Then carefully worm it between the large trim piece and the rest of the console starting at the rear nearest the cup holders. You will be able to lift the trim up enough to squeeze another screwdriver in there. Work your way around left and right until you can get your fingers under the trim. Then slide your fingers under and pull up to disengage clips. There are clips to the left and right of the shifter and then closer to the climate control. You will be able to pull up/back and disengage all of these clips. Then you have to worm the trim out from under the climate control. I found it to be easier to remove the trim with the shifter in either the 3rd gear or 2nd gear position.

Once you have the large trim piece free, you can either turn the piece carefully to one side or the other, or you can remove the trim entirely by disconnecting the hazard switch, power outlet, and compartment light harnesses. Now open the Velcro strips from each other so you can slip the boot over the shift knob and pull it down snug around the silver shift indicator piece, making sure to get the stitched seams positioned at the four corners. Carefully reinstall the trim piece (with black gasket in place) back over the shifter and under the climate control. It will take some effort to get the trim & gasket back over the leather and shift plate, but if you start at one corner and work your way around it will go on. The snug fit between gasket & leather will keep the boot in place. Now snap the trim back in place. Here is a more pictoresque documentation! 🙂

How to Install RedLineGoods 6-Speed Transmission Shift Boot on 2002-2003 Nissan Maxima

Credit: redlinegoods

1. In order to remove the front section, you must first remove the shift knob (just unscrew it from the shifter shaft – if it’s difficult, use vice grips on it after wrapping it with a towel to protect it from scratches). Then remove the liner of the shifter. That is easy, just pull on your shift boot and it pops up…picture shows this.

Replace the old boot with the new one installing it to the trim pieces taken out from the old boot. VERY simple and straightforward.

2. In order to install the ebrake boot, it is better to remove the armrest console. This will make it look easier since you need to attach the boot to the same holes/slits as the stock rubber boot. There is a screw inside the armrest, accessible from the back…

3. … and two more, one on each side of the console.

4. Next you need to remove the cloth ashtray cover. Underneath it there is a screw you need to remove.

5. Now simply lift the lower section of the center console. It will snap off and you will see 2 screws located below it.

6. Remove those 2 screws. You will also see that the armrest console is connected with 2 snap-ins from the sides of the center console. You can pull those on the side to separate them. It sounds confusing, but once you do this… the whole armrest console comes up.

7. When installing the ebrake boot, we suggest you take the rubber boot off and put the ebrake boot on it’s it place. It’s obvious which side is which, since one side is all slits, and the other side is a line of studs. once you have it in, put the the rubber boot back on…. It will hold the leather boot in place. It feels like a tight fit, but it’ll make the leather nice and snug.

Putting the center console on is the reverse order of removing it: put the 3 back screws back in (1 in armrest, 2 on the rear sides) and then the front 2 screws under the shifter, 1 in the ashtray and the 2 clips on the sides of the center console.

If you want to have the top of the ebrake boot at a certain point, here’s a suggestion: the boot is folded on the top. if you make a small slit on the underneath of the fold, you can fit a cable tie through, line up to where you want it, then tie it up, and one is the wiser. It can’t be seen since it’s on the underside of the ebrake handle.

ENJOY YOUR NEW LEATHER BOOTS!

Useful tip

You have installed a product made out of genuine leather. As you know, to maintain a leather product in good condition, you should take care of it. We suggest occasionally (every 4-6 week for example) applying some leather conditioner/UV protector to keep your leather from drying up in the sun and cracking.

2002-2003 5thgen Nissan Maxima OEM Mass Airflow (MAF) Replacement MAF0095 <$100 Bucks

Community Member Credit: Eddy

Wanted to make this reference post for folks that have MAF (Mass Airflow) issues and want to get an cost effective OEM replacement. I have to give credit to TallTom who gave me the idea to try this out. There are various aftermarket options out there but are known to have issues. OEM is the best replacement brand for MAF sensors. The main problem with buying from Nissan is the OEM (Part # 22680-AM600) heft price which is usually around $400 bucks (yeap insane).

The good news is that you can buy an OEM brand for your 2002-2003 Maxima without the crazy price. Hitachi is the OEM supplier for many Nissan Parts. The part number you need is MAF0095. There is another listed as MAF0099 but its much higher in price so make sure to order the MAF0095. We’ve tried this on our own 2002 Nissan Maxima and it worked perfect with no issues. You will notice that it says “for Pathfinder” but this will work fine on your 2002-2003 Maxima.

Update 12/16/2020: Ordered this for my 5.5 Nissan Maxima. Works perfect and just as it would from the factory.

Alternative Options

Another common option that I’ve noticed is that people buy a 2k1 MAF which is cheaper and then do the thermistor/IAT swap. The 2k1 MAF is around $80 bucks and require the swap as mentioned. With the above you don’t need to do anything as it is direct plug-n-play. However, if you still want to save a few bucks can check the 2k1 conversion to 2k2 MAF write-up here:

https://www.my4dsc.com/swap-2002-maxima-mass-airflow-sensor-maf-2001/

The most ideal option is to swap to the 04+ Nissan Maxima MAF which uses the newer style slot. This is recommended for those who are going to do performance build and will get tuned. You can read more details on it here. Just keep in mind that this option requires proper tuning for optimal use.
