Error code 0051 on the dashboard Nissan - one of the most common problems faced by model owners Qashqai, X-Trail, Juke and others. This error is due to a fault in the system ABS/VDC/ESP, but its causes can vary from a banal sensor failure to serious problems with the control unit. Unlike engine errors (eg. P0300), which are often ignored, 0051 requires immediate attention - Ignoring this may result in failure of the brake system or loss of control over the vehicle on a slippery road.

In this article we will look at:

  • 🔍 What does error 0051 mean? and what systems it is connected to

What does error 0051 mean on Nissan?

Code 0051 in the self-diagnosis system Nissan points to malfunction in the wheel speed sensor circuit. This error is related to the system ABS (Anti-lock Braking System), but may also affect related systems:

  • 🔄 VDC (Vehicle Dynamic Control) - stability control
  • 🚘 ESP (Electronic Stability Program) — electronic stabilization
  • 🛑 BA (Brake Assist) — emergency braking system

When the ECU (electronic control unit) detects an incorrect signal from one or more speed sensors, it activates an error 0051 and can:

  • ⚠️ Light up ABS indicator on the dashboard
  • 🚨 Disable VDC/ESP (the corresponding light on the panel will light up)
  • 🔴 In rare cases - block part of the brake system functions

Critical Feature: On some models (e.g. Nissan Qashqai J11) error 0051 can mask more serious problems with the ABS unit, which lead to complete brake failure during emergency braking.

On which Nissan models does error 0051 occur?

Error 0051 most typical for cars Nissanreleased after 2010, when the manufacturer began to actively implement electronic stabilization systems. Most often it occurs on the following models:

Model Years of manufacture Frequency of occurrence Typical reason
Qashqai J10/J11 2007–2021 ⭐⭐⭐⭐⭐ Oxidation of ABS sensor connectors, unit malfunction
X-Trail T31/T32 2007–2020 ⭐⭐⭐⭐ Damage to the wiring to the rear wheel sensors
Juke F15 2010–2019 ⭐⭐⭐ ABS unit malfunctions after firmware update
Note E12 2012–2020 ⭐⭐ Contamination of sensors with metal shavings
Navara D40 2005–2015 ⭐⭐ Contact corrosion in ABS connectors

By car Nissan to 2007 (For example, Primera P12 or Almera N16) error 0051 is extremely rare, since they used simpler versions of ABS without integration with VDC.

If your car not included in this list, but an error appeared - check if it was installed on it abnormal stabilization system or the ECU has not been chip-tuned.

💡

On models Nissan Leaf (electric car) error 0051 may indicate problems with the speed sensors in the regenerative braking system. In this case, diagnostics of the high-voltage part is required!

Reasons for error 0051

Error 0051 never occurs on its own - it is always preceded by some kind of malfunction. Let's consider all possible reasons, from simple to complex:

1. Damaged or dirty ABS sensors

Wheel speed sensors are located next to wheel bearings and often suffer from:

  • 🧲 Metal shavings (hits when bearings or brake discs wear out)
  • 💧 Corrosion (especially on the rear sensors due to their close location to the road)
  • 🔌 Broken wiring (rubbing of insulation against suspension elements)

On Nissan Qashqai J11 And X-Trail T32 fail more often rear sensors, since their wires pass close to the exhaust system and can melt.

2. ABS unit malfunction

ABS control unit (aka hydromodulator) may give an error 0051 for the following reasons:

  • 🔥 Overheating (for example, after a long off-road drive)
  • 💻 Firmware failure (often after a failed software update)
  • 🔌 Oxidation of contacts inside the block (typical for cars older than 10 years)

Important! On Nissan Juke F15 And Note E12 The ABS unit often fails after short circuit in the sensor circuit, so before replacing the unit, be sure to check all sensors!

3. Wiring problems

Error 0051 may appear due to:

  • 🔌 Open or short circuit in the sensor wiring harness
  • 🔋 Poor contact in connectors (especially after suspension repair)
  • 🐀 Damage by rodents (relevant for cars parked on the street)

On Nissan X-Trail T31 The wires of the front wheel sensors often fray at the point of attachment to the shock absorber strut.

4. Other reasons

Less commonly, the error occurs due to:

  • 🔄 Incompatible ECU firmware (for example, after chip tuning)
  • 🔋 Problems with the on-board network (low voltage, surges)
  • 🛠️ Mechanical damage (for example, after an accident)
How to check which sensor is at fault?

If you have a diagnostic scanner (such as Launch X431 or ELM327), connect it and view the sensor parameters in real time. A sensor that displays “0 km/h” when driving or has erratic readings is most likely faulty.

How to diagnose error 0051?

Diagnosis of the error 0051 must pass step by step, from simple to complex checks. Below - algorithm of actions, which will help identify the cause without extra costs.

Step 1: Visual Inspection of ABS Sensors

Start by inspecting all four sensors:

  1. Raise the car on a lift or jack (be sure to secure it!).
  2. Locate the speed sensors on each wheel (usually located near wheel bearing).
  3. Check:
    • 🔍 Wiring integrity (are there any fractures, meltings)
    • 🧲 Sensor cleanliness (are there any metal shavings)
    • 🔌 Connector tightness

If the sensor is dirty, clean it soft brush (do not use metal objects!).

Step 2: Check the sensor resistance

For this you will need multimeter:

  1. Disconnect the sensor connector.
  2. Measure the resistance between the sensor contacts:
    • ✅ Normal value: 800–1400 ohms (depending on model)
    • ❌ Break: resistance tends to infinity
    • ❌ Short circuit: resistance close to 0
  • Ring the wires for open or short to ground.

    • On Nissan Qashqai J11 The resistance of the front sensors is usually ~1000 Ohm, rear - ~1200 Ohm.

    Step 3: Diagnostics with a scanner

    If visual inspection and testing with a multimeter do not produce results, connect diagnostic scanner (For example, Launch CReader or ELM327 with the program Nissan DataScan).

    Please note:

    • 📊 Speed sensor readings in real time (must match on all wheels when moving)
    • 🔍 Additional errors (For example, C1130 — malfunction of the right front wheel sensor)
    • 🔄 ABS unit condition (are there any errors in voltage, communication with the ECU)

    Important! On some models (for example, Nissan X-Trail T32) error 0051 can only appear when moving, but in the parking lot the scanner will not show it. In this case, you need to carry out test drive with a connected scanner.

    How to resolve error 0051?

    The solution depends on reasons for the error. Below - step by step instructions for every occasion.

    1. Replacing or cleaning the ABS sensor

    If the sensor is dirty or damaged:

    1. Remove the wheel and locate the sensor (usually it is attached with one bolt on the 10 mm).
    2. Disconnect the connector and remove the sensor.
    3. Clean it of dirt and metal shavings (use WD-40 and a soft brush).
    4. Check gap between sensor and drive disk (must be 0.5–1.5 mm).
    5. Reinstall the sensor and check the error.

    If the sensor is faulty, replace it. Article numbers of original sensors for popular models:

    • Nissan Qashqai J11: 40520-4M000 (front), 40521-4M000 (rear)
    • Nissan X-Trail T32: 40520-BM00A (front), 40521-BM00A (rear)

    Advice: When replacing the sensor, be sure to check wheel bearing condition - if it is worn out, metal shavings will quickly damage the new sensor.

    2. Repair or replacement of the ABS unit

    If the problem is in the ABS unit:

    1. Remove the block (usually located next to master brake cylinder).
    2. Check contacts for oxidation (clear contact fluid).
    3. If the unit is faulty, replace it. Articles:
      • Nissan Qashqai J11: 40500-4M000
      • Nissan X-Trail T32: 40500-BM00A

    ⚠️ Attention! After replacing the ABS unit, you must bleed the brake system and execute initialization of sensors using a diagnostic scanner (for example, Launch X431). Without this, the error may remain!

    3. Wiring repair

    If the problem is in the wires:

    1. Find the location of the break or short circuit (use multimeter in dialing mode).
    2. Restore the circuit:
      • 🔧 Soldering iron (most reliable)
      • 🔌 Twisted with insulation (temporary solution)
  • Isolate the repair area heat shrink tube.

    • On Nissan Juke F15 wires often fray in the corrugation next to suspension arm - check this area first.

    4. Resetting the error and flashing the ABS unit

    If the error appears after a software update or failure:

    1. Connect the diagnostic scanner.
    2. Execute error reset (function Clear DTC).
    3. If the error returns, reflash the ABS unit (required special equipment, for example, Nissan Consult).

    ⚠️ Attention! Incorrect firmware of the ABS unit may completely disable it. If you have no experience, contact the service!

    💡

    On models Nissan Leaf After replacing the ABS unit, additional calibration of the regenerative braking system is required!

    Advice: Before replacing the ABS unit, check all sensors and wiring - often the problem lies in them, and not in the block itself.

    What happens if you ignore error 0051?

    Many drivers have been driving with errors for years 0051, unaware of the consequences. However, ignoring this problem can lead to:

    • 🚗 ABS failure — the wheels will lock during emergency braking, which will lead to skidding.
    • 🔄 Disabling VDC/ESP - the car will become less stable on slippery roads.
    • 💥 Increased wear of brake pads and discs (due to uneven braking).
    • 🚨 Problems during maintenance - ABS error is critical for technical inspection.

    On Nissan Qashqai J11 And X-Trail T32 ignoring the error 0051 can lead to complete failure of the brake system due to overheating of the ABS unit. This is especially dangerous when towing a trailer or driving off-road.

    ⚠️ Attention! On vehicles with electronic gas pedal (For example, Nissan Juke F15) ABS error can cause problems with engine operation, since the engine ECU and ABS communicate via the bus CAN.

    Frequently asked questions (FAQ)

    Is it possible to drive with error 0051?

    Technically yes, but highly not recommended. Without working ABS and VDC, the car becomes less controllable, especially on wet or icy roads. If the error appears suddenly, get to the service at a speed of no more than 60 km/h, avoiding sudden braking.

    Error 0051 only appears at speeds above 40 km/h. What is the reason?

    Most likely the problem is speed sensor, which begins to fail as the signal frequency increases. Check:

    • 🔍 Gap between sensor and drive disc (must be 0.5–1.5 mm).
    • 🧲 Sensor cleanliness (metal shavings may interfere with signal reading).
    • 🔌 Quality of contact in the connector (sometimes reconnecting helps).

    After replacing the wheel bearing, error 0051 appeared. What should I do?

    Most likely, when replacing the bearing there was ABS sensor damaged or its wiring. Check:

    • 🔧 Sensor integrity (sometimes it is torn off when removing the hub).
    • 🔌 Connector connection (may not be fully inserted).
    • 🧲 Gap between sensor and new bearing (sometimes non-original bearings have a different drive disc size).

    Is it possible to reset error 0051 without a scanner?

    Yes, on some models Nissan the error can be reset disconnecting the battery:

    1. Disable negative terminal battery for 10–15 minutes.
    2. Plug it back in.
    3. Start the car and check if the error disappears.

    ⚠️ Attention! This method only works if there was an error temporary (eg due to voltage failure). If the problem is in the ABS sensor or unit, the error will return.

    How difficult is it to replace the ABS unit yourself?

    Replacing the ABS block with Nissan refers to complex operations for the following reasons:

    • 🔧 Required bleeding the brake system after replacement.
    • 💻 Necessary initialize a new block through a diagnostic scanner.
    • 🔌 You need to carefully disconnect brake pipesso as not to damage them.

    If you do not have experience working with the brake system, it is better to contact a service center. An error during replacement may result in complete loss of brakes!
