Nissan CONSULT 2: a complete guide to Nissan diagnostic software

Software Nissan CONSULT 2 is the official diagnostic tool developed by the company Nissan for professional servicing of brand vehicles. It allows you to read and reset errors, conduct in-depth diagnostics of electronic systems, program control units and calibrate sensors. Without this software it is difficult to imagine full-fledged servicing of modern models Nissan, starting from Qashqai And X-Trail and ending GT-R And Patrol.

Unlike universal scanners like ELM327 or Launch X431, CONSULT 2 provides access to unique features not available in third-party programs, for example, adapting the throttle, resetting service intervals or activating hidden modes of the on-board computer. However, working with it requires not only special equipment, but also knowledge - incorrect actions can lead to failures in the car’s electronic systems.

What is Nissan CONSULT 2 and what is it for?

Nissan CONSULT 2 is the second version of diagnostic software, replacing the outdated one CONSULT 1. She supports cars Nissan, Infiniti, as well as some models Renault And Datsun, released after 1996. The main difference from the first version is expanded compatibility with new communication protocols (for example, CAN-bus) and support for multimedia systems.

The program is used for:

• 🔍 Error diagnostics (reading and decoding codes DTC for all vehicle systems).
• 🔧 Programming control units (ECU, TCU, ABS, Airbag, etc.).
• ⚙️ Calibrations and adaptations (throttle valve, power windows, headlights).
• 📊 View parameters in real time (sensors, voltage, temperature).
• 🔄 Resetting service intervals and resetting maintenance counters.

It is important to understand that CONSULT 2 is not a universal solution for all models. For example, for Nissan Leaf (electric vehicle) requires specialized software CONSULT 3+, and for old cars up to 1996 - first version of the program. There are also regional restrictions: European, American and Japanese versions may differ in supported protocols.

⚠️ Attention: Using unlicensed versions CONSULT 2 may block access to the vehicle's diagnostic connector. The manufacturer is actively fighting piracy by updating protection.

Hardware requirements and compatibility

To work with Nissan CONSULT 2 It is not enough to simply install the program on your computer. Specialized equipment required:

Component	Requirements	Notes
Diagnostic adapter	Original Nissan CONSULT 2 or compatible (for example, VXDIAG VCX Nano)	Chinese clones may not support all features
Laptop/PC	Windows 7/10 (32 or 64-bit), minimum 4 GB RAM, USB 2.0 port	There may be driver problems on Windows 11
OBD-II cable	Standard connector J1962 (16-pin)	Older models may require an adapter 14-pin
Power supply	Stabilized voltage 12V (for adapter)	Using a cigarette lighter is not recommended

Particular attention should be paid to the choice of adapter. Original Nissan CONSULT 2 is expensive (from 1000$), so many people use alternatives like VXDIAG VCX Nano or MongoosePro Nissan. However, cheap Chinese clones often do not support ECU programming functions and may generate false errors.

It is also important to consider compatibility with car model:

• 🚗 Qashqai (J10, J11), X-Trail (T31, T32) - full support.
• 🚙 GT-R (R35), 370Z — additional software is required to configure the transmission.
• ⚡ Leaf (ZE0, ZE1) - only basic diagnostics, for deep settings you need CONSULT 3+.
• 🏜️ Patrol (Y61, Y62) — support depends on the year of manufacture (up to 2010 — CONSULT 2, after — CONSULT 3).

Where to download Nissan CONSULT 2 and how to install

Officially the program Nissan CONSULT 2 Distributed only through dealer centers and certified partners. However, you can find both licensed versions (usually sold together with adapters) and “hacked” assemblies on the Internet. Using pirated versions is fraught not only with legal consequences, but also with the risk of damaging the car’s electronic systems.

If you decide to purchase a license, contact official distributors, for example:

• 🌍 Nissan TechInfo (for USA and Europe).
• 🇯🇵 Nissan Global (for Japanese market).
• 🇷🇺 Official dealers Nissan in Russia (through service centers).

Installation process includes several stages:

1. Install drivers for the adapter (usually included).
2. Run the installer CONSULT 2 on behalf of the administrator.
3. Select your region (Europe, Asia, USA) - this will affect the supported protocols.
4. Activate the license (when purchasing the official version).
5. Update the error database (DTC) through the program menu.

⚠️ Attention: When installing on Windows 10/11, you may need to disable driver signature verification. To do this, enter (cmd on behalf of administrator):
bcdedit.exe /set nointegritychecks on

After installation, return the settings back: bcdedit.exe /set nointegritychecks off.

How to connect to the car and carry out diagnostics

After installing the program and drivers, you can start connecting. Procedure:

1. Connect the adapter to the diagnostic connector OBD-II (usually located under the steering wheel or in the glove compartment).
2. Connect the adapter to the laptop via USB or Bluetooth (depending on model).
3. Turn on the car's ignition (no need to start the engine).
4. Run the program Nissan CONSULT 2 and select your car model.
5. Click Connect and wait for the connection to be established.

If the connection was successful, you will see the main menu with sections:

• 🔴 Engine — engine and transmission diagnostics.
• 🔵 ABS/VDC — Anti-lock braking system and stability control.
• 🟢 Airbag (SRS) — airbags.
• 🟡 BCM — body control unit (window lifters, central locking).
• ⚫ Self-Diagnosis — automatic scanning of all systems.

To read errors, go to section Self-Diagnosis → Read DTC. The program will show a list of codes with a brief description. For example, P0300 - random misfires, C1130 - ABS sensor malfunction. For detailed decryption, use the database CONSULT 2 or third party resources like OBD-Codes.com.

Deciphering errors and resetting them

Error codes in Nissan CONSULT 2 are divided into several categories:

• 🔴 Pxxxx — engine and transmission errors (for example, P0171 - lean mixture).
• 🔵 Cxxxx — chassis (ABS, suspension, steering).
• 🟢 Bxxxx — body (window lifters, central locking).
• 🟡 Uxxxx — network errors (CAN-bus, communication between blocks).

To troubleshoot the problem, follow the algorithm:

1. Write down the error code and its description.
2. Check possible reasons (eg for P0300 it could be spark plugs, ignition coils or air leaks).
3. Eliminate the malfunction (replace part, clean contacts, etc.).
4. Reset the error via Self-Diagnosis → Erase DTC.
5. Take it for a test drive and see if the error appears again.

Some errors are "floating" and may appear periodically. For example, P0420 (low catalyst efficiency) often occurs due to low-quality fuel and disappears after several refuelings. Others like C1145 (ABS pump malfunction) require immediate attention.

What to do if the error does not clear?

If the error code appears again after resetting, the problem has not been resolved. In some cases it is required flashing the control unit or replacing a faulty sensor. For example, error P0100 (malfunction of the mass air flow sensor) will not disappear until the mass air flow sensor is replaced or cleaned.

Programming and calibration of control units

One of the key features Nissan CONSULT 2 - opportunity programming and calibration electronic units. This may be necessary after replacing the ECU, repairing the engine, or installing new equipment. For example:

• 🔧 Throttle valve adaptation (necessary after cleaning or replacement).
• 🔄 Resetting service intervals (resetting the maintenance counter).
• 📶 Setting up immobilizer keys (if you lose or add a new key).
• 🔊 Window calibration (after replacing the mechanism).

Example of throttle valve adaptation:

1. Connect to the car and select a partition Engine → Work Support.
2. Find an item Throttle Valve Closed Position Learning.
3. Follow the instructions on the screen (usually you need to press the gas pedal all the way down and release).
4. Once completed, reboot the ECU by disconnecting the battery at 10 minutes.

To program a new ECU you will need:

• Firmware file (usually provided by the dealer).
• Special activation key (linked to the vehicle VIN).
• Stable power supply (it is recommended to connect the charger to the battery).

⚠️ Attention: Incorrect ECU programming may result in complete engine blocking. If you are not sure of your actions, contact the service center. For example, when flashing a block ABS on Nissan X-Trail T32 The sequence of commands must be strictly followed, otherwise the system may no longer recognize the wheel sensors.

Common problems and their solutions

When working with Nissan CONSULT 2 Users often encounter 典型 errors. Here are the most common of them and how to eliminate them:

Problem	Possible reason	Solution
No Communication (no connection)	Adapter is faulty, poor contact in the OBD-II connector, ignition is turned off	Check the connection, reboot the adapter, turn on the ignition
Error DTC P1614 (immobilizer)	Key mismatch with ECU, battery low	Check the key, charge the battery, perform the key learning procedure
The program freezes when reading errors	Conflict with antivirus, outdated software version	Disable your antivirus, update CONSULT 2 up to the latest version
Can't clear error C1130 (ABS)	ABS sensor or control unit is faulty	Check the sensors on the wheels, measure the resistance (should be 800-1400 Ohm)

If the program gives an error "Vehicle Not Supported", this means your car model is not compatible with the current version CONSULT 2. In this case:

• Check if required CONSULT 3+ (for new models).
• Update the vehicle database via the menu Update.
• Make sure you select the correct region (Europe/Asia/USA).

For diagnostics Nissan Leaf and other electric vehicles may require additional software, e.g. Leaf Spy Pro (for battery monitoring) or CAN-Do (for working with high-voltage systems).
