Diagnostic scanner Nissan CONSULT 2 (or CONSULT-II) is a professional tool, without which it is impossible to fully service brand vehicles Nissan after 2000. It allows you to read errors DTC, adapt control units, update firmware and even activate hidden functions. But working with it requires knowledge: from choosing the original adapter to correctly connecting to ECU through OBD-II connector

In this article you will find step by step instructions by connection CONSULT 2 to different models Nissan (from Qashqai to Patrol), let's deal with unique errors that cheap scanners do not show, and we’ll tell you how to avoid typical diagnostic problems. And also - where to buy an original adapter and how to distinguish it from a Chinese counterfeit, which can burn control units.

What is CONSULT 2 and why Nissan owners need it

Nissan CONSULT 2 is a second generation diagnostic interface, Released in 2002 for working with electronic vehicle systems Nissan, Infiniti, Renault And Datsun. Unlike universal scanners (like ELM327), it interacts with control units on protocol level, which allows:

  • 🔧 Read all errors, including hidden (UXXXX, CXXXX for chassis).
  • 🔄 Program keys, adapt throttle, reset service intervals.
  • 📈 View live-data (real-time sensor parameters) with a frequency of up to 10 Hz.
  • 🔧 Update block firmware (ECU reflash) via official files Nissan.
  • 🔐 Activate hidden features (e.g. AVM — all-round view of X-Trail T32).

Without CONSULT 2 some operations are simply impossible. For example, after replacing Automatic transmission on Nissan Juke required variator adaptation - otherwise the box will work in emergency mode. Or after replacement ECU on Patrol Y62 you need to “bind” the unit to the immobilizer, otherwise the engine will not start.

⚠️ Attention: Cheap Chinese adapters CONSULT 2 (price up to 5000₽) often do not support protocols CAN FD And K-Line, due to which they cannot read errors on the chassis or airbags. In the worst case they can damage the ECU when trying to flash the firmware.

Which Nissan models does CONSULT 2 support?

CONSULT 2 compatible with all cars Nissan, released after 2000, but there are nuances:

  • 🚗 Qashqai J10/J11, X-Trail T31/T32, Murano Z50/Z51 — full support, including CVT adaptation CVT-7.
  • 🚙 Patrol Y61/Y62, Navara D40/NP300 — additional adapter for diagnostics is required 4WD And VLSD.
  • 🚘 Almera N16/G15, Tiida C11/C13 - supported, but for firmware ECU you need software version no lower v5.10.
  • ⚡ Leaf ZE0/ZE1 - only works with original adapter (Chinese clones do not read high-voltage batteries).
Model CONSULT 2 support Features
Nissan Qashqai J11 (2013–2021) ✅ Full Adaptation required EPS after replacing the steering rack.
Nissan X-Trail T32 (2014–present) ✅ Full Supports activation AVM (all-round view) and setting ProPILOT.
Nissan Patrol Y62 (2010–present) ✅ Partial For diagnostics VLSD need extra adapter Nissan MUX.
Nissan Leaf ZE1 (2017–present) ⚠️ Limited Chinese clones do not read high voltage battery data (EV-ECU).
Nissan Almera G15 (2012–2018) ✅ Full For firmware ECU software version needed v5.10+.

If your model is older than 2000 (for example, Nissan Primera P12 or Maxima A33), then for diagnosis you need CONSULT 1 or adapter with support ISO9141. More details about compatibility can be checked in the official documentation Nissan by VIN-car code.

How to connect CONSULT 2 to Nissan: step-by-step instructions

To connect CONSULT 2 you will need:

  • 🔌 Original adapter Nissan CONSULT 2 (or a verified clone with a chip FT232R).
  • 💻 Laptop with Windows 7/10 (on Windows 11 there may be problems with the drivers).
  • 🔄 Cable OBD-II → CONSULT 2 (included).
  • 📥 Software Nissan DataScan II (version no lower v5.10).

Next follow the instructions:

  1. Install drivers for the adapter (you can download it on the website Nissan TechInfo).

  2. Connect the adapter to OBD-II car connector (usually located under the steering wheel).

  3. Run the program DataScan II and select your car model by VIN.

  4. On the menu Diagnosis → Self Diagnostic Results select the block to scan (for example, Engine or AT).

  5. Click Start and wait for the diagnostics to complete.

Make sure the ignition is on (engine off)|Check the OBD-II cable connection|Install drivers for the adapter|Run DataScan II as administrator|Select the correct model by VIN-->

If the adapter is not detected, check:

  • 🔌 Connect to OBD-II (pins 6 and 14 must be active).
  • 💻 OS compatibility (on Windows 11 compatibility mode may be required).
  • 🔄 Software version (for Nissan Leaf needed v6.0+).
⚠️ Attention: When connecting to Nissan GT-R R35 or 370Z never update firmware ECU through unofficial files. This may lead to engine blocking and the need for reflashing at the dealership.

What errors can CONSULT 2 show (and what do they mean)

CONSULT 2 reads all types of errors, including those that cannot be seen by universal scanners. Here are the most common:

Error code Description Possible reason
P0300 Multiple misfires Faulty spark plugs, coils, low compression.
U1000 Lack of communication with ECU Problems with CAN bus or power supply of the unit.
C1130 Sensor error ABS The wire or the sensor itself is damaged.
B210E Immobilizer error Key mismatch or failure NAT-System.

Particular attention should be paid to series errors UXXXX - they point to problems with communication between blocks. For example, U1010 on Nissan X-Trail often means a break CAN buses between ECU And TCM (gearbox unit).

If you see an error B210E (immobilizer), then without CONSULT 2 it cannot be eliminated - it will be necessary retraining keys via menu Immobilizer → Registration.

What to do if CONSULT 2 does not see an error?

If the scanner does not show an error, but the machine is clearly faulty, check:

1. **Software version** - for new models (for example, Ariya) needed DataScan II v6.0+.

2. **Connection to OBD-II** - pins 6 (CAN-H) and 14 (CAN-L) must be intact.

3. **State of fuses** - on Nissan Qashqai J11 The fuse is responsible for diagnostics #32 (10A) in the block under the hood.

4. **Presence of “hidden” errors** - some DTC (For example, U1001) are not displayed in the main menu, you need to look for them in Self-Diagnosis → History.

Where to buy the original CONSULT 2 and how not to run into a fake

Original Nissan CONSULT 2 costs from 30,000 to 50,000₽, but the market is full of fakes for 3000–8000 rubles. Here's how to distinguish the original:

  • 🔍 Adapter body - the original has a logo Nissan and serial number on the back cover.
  • 🔌 OBD-II connector - fakes often have low quality plastic, and the contacts quickly oxidize.
  • 💾 Firmware - the original is determined in DataScan II how CONSULT-II (Genuine).
  • 📦 Equipment - there should be a cable in the box USB → CONSULT 2, software disc and instructions.

Where to buy:

  • 🛒 Official dealers Nissan — 1 year warranty, but the price is maximum.
  • 🌍 Foreign sites (For example, Nissan TechMate) - cheaper, but delivery is long.
  • 🛠️ Verified service centers — sometimes they sell used originals after they have been written off.
⚠️ Attention: Fakes often do not support protocols CAN FD (needed for Nissan Ariya And Leaf after 2020) and may damage the ECU when trying to flash the firmware. Before purchasing, check the seller's reviews and request a photo of the serial number.
💡

Before buying used CONSULT 2 ask the seller to take a screenshot from DataScan II with information about the adapter. The original will display the string "Interface: CONSULT-II (Genuine)", and the fake is "Clone" or "Emulator".

Typical problems when working with CONSULT 2 and how to solve them

Even with the original adapter, errors may occur. Here are the most common ones and how to fix them:

Problem Reason Solution
No Communication Break CAN buses or a faulty adapter. Check fuses, contacts OBD-II, try a different adapter.
Version Mismatch Outdated software DataScan II. Update the program to v6.0+ (you can download it at official website).
Security Access Denied Immobilizer lock. Enter the PIN code (specified in the service book) or reset via Immobilizer → Reset.

If CONSULT 2 does not see a specific block (for example, TCM on Nissan X-Trail), try:

  1. Restart the program and adapter.
  2. Check the power supply to the unit (fuses #10 And #20 in the cabin).
  3. Update the adapter firmware via Firmware Update in DataScan II.
💡

If CONSULT 2 can't connect to ECU on Nissan Leaf, check if the mode is enabled "Service Mode" (hold down the brake pedal and press the button Power 3 times in a row).

Alternatives to CONSULT 2: when you can do without it

If you only need basic diagnostics (reading errors PXXXX), then you can use alternatives:

  • 📱 ELM327 adapters (For example, VGate iCar 2) - suitable for reading engine and gearbox errors, but do not work with NAT-System (immobilizer).
  • 💻 Launch X431 - supports Nissan, but not all functions (for example, cannot flash TCM on Qashqai J11).
  • 🔧 OpenPort 2.0 - works with Nissan through Tactrix, but requires knowledge ROM ID people.

However for serious operations (firmware, variator adaptation, work with immobilizer) CONSULT 2 remains the only reliable solution. For example, after replacing Automatic transmission on Nissan Murano impossible to do without it torque converter initialization.

FAQ: Frequently asked questions about CONSULT 2 for Nissan

Can CONSULT 2 be used on Nissans older than 2000?
