Error C1105 on Nissan: a complete analysis of causes and solutions

• 🔌 Wiring — breaks, short circuits or oxidation of contacts;
• 🛠️ Wheel bearing — wear or play affecting the sensor signal;
• 📡 ABS/VDC unit — internal failures in the control module;
• 🔄 Incompatibility of spare parts - if the sensor or hub was replaced with non-original ones.

It is important to understand that C1105 - this is not a sentence, but an indication of the search area. For example, on Nissan Qashqai J10/J11 This error often occurs after replacing the hub or brake pads when the sensor is accidentally damaged. On X-Trail T31/T32 The culprit may be corrosion in the sensor connector due to moisture.

⚠️ Attention: If the error C1105 accompanied by burning lamps ABS And VDC At the same time, driving a car becomes unsafe - the braking system can work unpredictably, especially on slippery surfaces.

Reasons for error C1105

To effectively eliminate C1105, you need to understand its root cause. Let's look at the most common scenarios:

1. Mechanical damage to the sensor. The wheel speed sensor is located near the hub and often suffers from impacts (for example, when replacing a brake disc) or corrosion. On Nissan Juke And Note The sensors are particularly vulnerable due to their compact suspension.
2. Wheel bearing wear. When there is play in the bearing, the gap between the sensor and the drive disk increases, which leads to loss of the signal. Typical for used cars 100,000 km.
3. Wiring problems. Breaks or short circuits in the harness going from the sensor to the block ABS, often occur after unqualified repairs or an accident. On Nissan Pathfinder R51 wires may rub against suspension elements.
4. Malfunctions in the ABS/VDC unit. Internal module faults (for example, failure of microcircuits) can simulate a sensor error. This is the most expensive repair option.

Interesting fact: on Nissan Almera N16 And Primera P12 error C1105 sometimes appears after battery replacement or reset settings ECU. In this case, rebooting the system helps (disconnecting the battery terminal for 10 minutes).

Diagnosing error C1105: step-by-step instructions

Before rushing to change the sensor, conduct a comprehensive diagnostic. Here is the algorithm of actions:

1. Read the error codes with a scanner.

   Use a diagnostic scanner (eg Launch CReader or ELM327) to confirm C1105. Make sure there are no associated errors (eg C1100 — open circuit of the sensor).

2. Visual inspection of the sensor and wiring.

   Remove the right front wheel and inspect:

   • 🔍 Integrity of the sensor body (cracks, chips);
   • 🔌 Condition of the connector (oxidation, moisture);
   • 📏 The gap between the sensor and the drive disk (must be 0.5–1.5 mm).

⚠️ Attention: On Nissan Murano Z50/Z51 Wheel speed sensors are integrated into the wheel bearing. Replacing them requires completely dismantling the hub and pressing in a new bearing with a sensor.

How to resolve error C1105: from simple to complex

Depending on the cause, repair methods vary from basic to major. Let's start with the most accessible ones:

1. Cleaning contacts and connectors

Often a mistake C1105 occurs due to oxidation of contacts in the connector of the sensor or unit ABS. Proceed like this:

• 🧹 Disconnect the sensor connector and clean the contacts alcohol solution or a special liquid (for example, Contact Cleaner).
• 🔧 Check the fixation of the connector - it should fit tightly, without play.
• 💧Apply to contacts dielectric grease for protection against moisture.

2. Replacing the wheel speed sensor

If the sensor is damaged or its resistance is not normal, replacement will be required. When choosing a spare part, consider:

• 🔍 Original articles:
  • Qashqai J10: 40520-4M000 (right front wheel);
  • X-Trail T31: 40520-AL500;
  • Juke F15: 40520-4M200.
• ⚠️ Avoid cheap analogues - they often give false signals.
• 🛠️ When replacing, do not use a hammer - the sensor is fragile, install it carefully.

3. Wiring repair

Breaks or shorts in the sensor harness are a common problem. For repair:

1. Test the wires with a multimeter in 200 Ohm (check for continuity) and 20 MOhm (check for short to ground).
2. If a break is found, strip and solder the wires, insulating them with heat shrink.
3. In case of severe damage, replace the entire harness (part number for Qashqai J11: 25460-4M000).

4. Replacing the wheel bearing

If the play in the bearing exceeds 0.05 mm, it needs to be replaced. On Nissan bearings are often used NSK or NTN. Example of articles:

• Qashqai J10: 40530-4M000 (hub assembly with bearing);
• X-Trail T32: 40530-1X000.

5. Diagnostics of the ABS/VDC unit

If all the previous steps did not help, the problem may lie in the block ABS/VDC. Its renovation includes:

• 🔧 Reflashing the module (sometimes helps with software failures);
• 🛠️ Replacement of faulty components (transistors, capacitors) on the board;
• 💻 Complete replacement of the block (original for Qashqai J11: 40500-4M000, price ~30,000 ₽).

1. Disconnect the battery for 15 minutes.

2. Connect the scanner and follow the procedure "ABS Initialization" (if available).

3. Drive 5–10 km at a speed >50 km/h to calibrate the sensors.-->

Common repair mistakes and how to avoid them

Many car owners aggravate the problem by making common mistakes. That's what it's impossible do:

• 🚫 Ignore related errors. For example, C1105 can mask U1000 (loss of connection with the unit ECU). Always read everything codes!
• 🚫 Install the sensor without checking the gap. Too large a gap (>2 mm) will cause the error to reappear.
• 🚫 Save on wiring. Using twists instead of soldering or electrical tape instead of heat shrink can result in a short circuit.
• 🚫 Reset the error without eliminating the cause. If you just erase C1105 scanner, she will return after a few kilometers.

On Nissan Teana J32 And Maxima A35 A common mistake is when, after replacing the hub, they forget to move the magnetic ring (drive disk) from the old bearing to the new one. Without it, the sensor will not generate a signal.

⚠️ Attention: On vehicles with the system 4WD (For example, X-Trail or Pathfinder) a faulty wheel speed sensor can lead to activation of the cross-axle differential lock. This is manifested by jerking when turning and accelerated wear of the transmission.

When to contact an official dealer?

Not all problems associated with C1105, you can fix it yourself. Contact the service if:

• 🔧 After replacing the sensor and checking the wiring, the error remains;
• 📉 Diagnostics shows a faulty unit ABS/VDC;
• 🚗 The car behaves unpredictably when braking (jerking, wheel locking);
• 💻 Re-flashing or replacement of the control unit is required.

Cost of diagnostics in the official service Nissan is about 1 500–2 500 ₽, but it is justified when it comes to safety. For example, on Nissan Patrol Y62 block ABS integrated with the system Hydraulic Body Motion Control, and its incorrect operation can lead to loss of controllability off-road.

Prevention of error C1105

To avoid reappearance C1105, follow simple rules:

• 🛠️ Inspect sensors regularly when replacing brake pads or discs.
• 🚿 Avoid high pressure washing of suspension - Water may get into the connectors.
• 🔧 Use original spare parts or proven analogues (Bosch, Febi).
• 📊 Reset errors periodically scanner, even if the lamp ABS does not burn.

On Nissan Ariya and other electric crossovers, errors in wheel speed sensors can affect the operation of the regenerative braking system. Therefore, their diagnosis must be especially thorough.
