Error C1106 on Nissan: interpretation, causes and repair

Error code C1106 on cars Nissan - one of the most common problems in the system ABS/VDC, which can take even experienced drivers by surprise. This error indicates a fault in the circuit wheel speed sensor (usually the rear right), but its true causes often lie deeper - from banal oxidation of contacts to serious problems with the control unit. In this article we will look at why C1106, how to diagnose it correctly and what to do to get rid of it forever - without extra expenses for a car service.

The peculiarity of this error is that it can manifest itself in different ways: from a flashing light ABS until the stability control system is completely turned off (VDC). In some cases, the car even goes into “limp mode,” limiting engine power. We have collected up-to-date information for 2026, including nuances for popular models Nissan Qashqai, X-Trail And Juke, as well as detailed instructions for self-repair.

What does error code C1106 mean on Nissan?

Code C1106 in the diagnostic system Nissan stands for “Rear right wheel speed sensor circuit malfunction”. However, this general description is often misleading. In practice, the error may indicate:

• 🔧 Problems with the sensor itself (break, short circuit, failure)
• 🔌 Wiring damage or oxidation of contacts in connectors
• 📱 Malfunctions in the ABS/VDC control unit (less often, but requires attention)
• ⚙️ Mechanical damage hub or bearing affecting the sensor signal

It is important to understand that C1106 - this is not a verdict, but only an indication of the area of ​​the problem. For example, on Nissan Qashqai J10/J11 This error often occurs after replacing a wheel bearing if the ABS sensor has been damaged or installed incorrectly. And on X-Trail T31/T32 The culprit is often corrosion in the connectors, especially in Russian winter conditions.

Interesting fact: on some models (for example, Nissan Juke) error C1106 may be accompanied by code C1130 - this indicates problems with ABS control unit, not with a sensor. In such cases, a comprehensive diagnosis is required.

The main causes of error C1106

To effectively resolve an error, you need to understand its root cause. We analyzed data from forums, service manuals and diagnostic reports to highlight TOP-5 reasons for cars Nissan:

Reason	Frequency of occurrence	Models where it occurs most often
Oxidation or damage to ABS sensor connectors	60%	Qashqai J10, X-Trail T31, Note E12
Open or short circuit in wiring	25%	Juke F15, Tiida C11, Almera G15
Malfunction of the ABS sensor itself	10%	All models, but more often after 100,000 km
Problems with the ABS/VDC control unit	3%	Pathfinder R51, Murano Z51
Mechanical damage to the hub/bearing	2%	Navara D40, Patrol Y62

In first place - problems with connectors. The fact is that the ABS sensors on Nissan often located in areas exposed to moisture and dirt (for example, near the wheel arch). Over time, the contacts oxidize and the plastic connector retainers break, resulting in a poor connection. This is especially true for cars older than 5 years.

The second most common reason is wiring damage. The wires from the ABS sensor run along the suspension and often rub against body elements or fasteners. For example, on Nissan Qashqai J11 a typical cliff location is the area next to rear suspension arm. In this case, the wire may visually look intact, but break inside.

⚠️ Attention! If the error C1106 appeared after replacing the wheel bearing, with a 90% probability the problem is a damaged ABS sensor. Many craftsmen touch the sensor when pressing out a bearing, which leads to its failure.

How to diagnose error C1106 yourself

For an accurate diagnosis you will need OBD-II scanner (For example, Launch CReader or ELM327), but some checks can be performed without it. We have compiled step-by-step instructions that will help identify the cause of the problem:

Visual inspection of ABS sensor connectors for oxidation and damage|

Checking the integrity of the wiring from the sensor to the ABS unit|

Measuring the resistance of the sensor with a multimeter (norm: 800–1400 Ohms)|

Checking the voltage at the ABS unit connector (should be 12V when the ignition is on)|

Reading additional errors with the scanner (for example, C1130 indicates the ABS unit)-->

Let's start with visual inspection. Raise the car on a jack or drive it into a pit, then:

1. Locate the rear right wheel ABS sensor (usually built into or located near the hub).
2. Disconnect the connector and check the contacts for oxidation, moisture or mechanical damage.
3. Make sure the connector lock is not broken and the contact is tight.

If everything is visually in order, proceed to checking the wiring. Often a break occurs in places where the wire bends or rubs against the body. Please note:

• 🔹Plot next to rear suspension arm (typical place of chafing).
• 🔹 Place where the tourniquet enters the cabin (usually next to rear door threshold).
• 🔹 Connector on the ABS block (may oxidize or be poorly fixed).

To check the sensor with a multimeter:

1. Switch the device to resistance measurement mode (2000 Ohm).
2. Connect the probes to the sensor contacts (polarity is not important).
3. Normal resistance - 800–1400 Ohm. If the readings fall outside these limits or the multimeter shows a break, the sensor is faulty.

It's also useful to check voltage at ABS unit connector (usually it is located under the hood next to the vacuum booster). When the ignition is turned on, there should be 12V. If there is no voltage, the problem is in the wiring or the ABS unit.

Step-by-step instructions for resolving error C1106

When the cause is found, repairs can begin. Below we provide 3 most common scenarios troubleshooting C1106 taking into account the nuances for different models Nissan.

1. Cleaning connectors and contacts

If the problem is oxidation or poor contact, proceed as follows:

1. Disconnect the ABS sensor connector and the locking clip (carefully so as not to break it!).
2. Clean your contacts with WD-40 or a special contact cleaner (Contact Cleaner).
3. Use fine sandpaper (1000-1500 grit) or an eraser to remove oxidation.
4. Apply to contacts silicone grease (not ordinary lithol!) to protect against moisture.
5. Check the connector lock - if it is broken, replace the entire connector.

After cleaning be sure to clear the error scanner or by disconnecting the battery terminal for 10 minutes. If the problem was in the contacts, the error C1106 will disappear.

2. Repair or replacement of wiring

If a break or short circuit is detected in the wires, there are two options:

• 🔧 Solder the damaged area (only if the break is small and the wire is not completely worn out).
• 🔄 Replace the entire harness (more reliable, but more expensive).

For soldering use:

• 🔥 Soldering iron with a power of 40–60 W.
• 🧵 Solder with rosin (not acid!).
• 🛡️ Heat shrink tube for insulation.

Important: after wiring repair check it for short circuit with a multimeter in “dialing” mode. If the resistance between the sensor wires and ground is less than 1 MOhm, there is a short circuit somewhere.

⚠️ Attention! On Nissan Qashqai J11 And X-Trail T32 The ABS wiring harness comes in the same bundle with the parking sensor wires. When soldering, be careful not to damage adjacent wires!

3. Replacing the ABS sensor

If the sensor is faulty, it must be replaced. To do this:

1. Remove the wheel and disconnect the sensor connector.
2. Unscrew the sensor mounting bolt (usually 10 or 12).
3. Carefully remove the sensor from the hub. If it gets stuck, use WD-40 and do not use excessive force to avoid breaking it.
4. Install a new sensor (original part number for Qashqai J11 — 40520-4M000, for X-Trail T32 — 40520-BM000).
5. Connect the connector and check for errors.

When replacing the sensor, pay attention to:

• 🔹 Sensor position relative to hub — the gap should be 0.5–1 mm.
• 🔹 O-ring integrity (if it is damaged, moisture will enter the connector).
• 🔹 Bolt tightening torque - usually 8–10 Nm (do not overtighten!).

Common repair mistakes and how to avoid them

Many drivers are faced with the fact that after self-repairing an error C1106 returns or new problems appear. We have collected TOP-3 errorswhich are allowed when troubleshooting this malfunction:

1. Ignore additional errors. For example, if together with C1106 There is C1130 (problems with the ABS block), cleaning the sensor contacts will not help - you need to diagnose the block.
2. Using non-original sensors. Cheap analogues often have a different resistance, which leads to false alarms. For example, on Nissan Juke non-original sensors may cause an error C1106 even with good wiring.
3. Incorrect sensor installation. If the sensor is installed skewed or too close to the hub, it will produce an incorrect signal. Optimal clearance - 0.5–1 mm.

Another common problem is damage to wiring when soldering. Drivers often overheat the wires with a soldering iron, which leads to melting of the insulation and a short circuit. To avoid this:

• 🔥 Use a soldering iron with a power of no more than 60 W.
• 🕒 Solder quickly, do not hold the tip on the wire for more than 3-5 seconds.
• 🛡️ Always insulate the soldering area with heat shrink tube.

On Nissan Note And Almera a situation often occurs when, after replacing a wheel bearing, C1106. The reason is that the craftsmen forget to rearrange magnetic ring (encoder) from the old bearing to the new one. Without this ring, the ABS sensor cannot read the signal and the system generates an error.

When is a visit to the service necessary?

In most cases the error C1106 can be eliminated on your own, but there are situations when you cannot do without professional help. Contact the service if:

• 🔧 After replacing the sensor and cleaning the contacts, the error remains, but the scanner shows C1130 (problems with the ABS unit).
• 🔌 The wiring is damaged over a large area, and its replacement requires disassembling the interior (for example, on Nissan Teana or Maxima).
• 📱 After resetting the error, it appears again after a few kilometers, and the cause cannot be identified.
• ⚙️ Along with C1106 the lamps are on ABS, VDC And Check Engine - this may indicate problems with CAN bus.

The service uses professional scanners for diagnostics (Nissan Consult, Launch X431), which allow:

• 🔹 Read real data from ABS sensors (not just error codes).
• 🔹 Check circuit integrity without disassembling the car.
• 🔹 Execute ABS/VDC unit calibration after repair.

The cost of diagnostics in the service is usually 1000–2000 rubles, and repairs (for example, replacing an ABS unit) - from 10,000 to 30,000 rubles depending on the model. On Nissan Patrol or Navara the price may be higher due to the difficulty of accessing the nodes.

⚠️ Attention! If after repair there is an error in the service C1106 appeared again, demand warranty repair. According to the Law “On the Protection of Consumer Rights”, you have the right to free re-repair within 14 days (Article 29).

Prevention of error C1106: how to avoid recurrence

To make a mistake C1106 did not return, follow these recommendations:

• 🚗 Clean ABS sensor connectors regularly (once every 2–3 years or at every maintenance). Use contact lubricant (For example, Liqui Moly Electronic-Spray).
• 🔧 Check the condition of the wiring when replacing rear brake pads or wheel bearings.
• 🌧️ Avoid driving through deep puddles — water may get into the sensor connectors.
• 🛠️ When replacing a wheel bearing Always check the integrity of the ABS sensor and magnetic ring.
• 📱 Read errors periodically scanner (for example, via an adapter ELM327 and application Torque). This will help identify the problem at an early stage.

By car Nissan with mileage over 100,000 km it is recommended:

• 🔹 Replace all ABS sensor connectors for new ones (the cost of one connector is about 500 rubles).
• 🔹 Lay the wiring in corrugation for protection against chafing.
• 🔹Use dielectric grease on the contacts of the ABS block.

Pay special attention winter period. Salt and reagents that are sprinkled on roads accelerate corrosion of contacts. After heavy snowfalls or driving through slush, wash the wheel arches and the area where the ABS sensors are located. warm water (do not use a pressure washer - it may damage the seals!).

What happens if you ignore error C1106?

If you drive for a long time with an error C1106, this will result in:

1. Disabling the system ABS (the car will brake as if without ABS, with the risk of wheel skidding).
2. Disabling the system VDC (directional stability), which is dangerous on slippery roads.
3. Increased wear of brake pads and discs due to uneven braking.
4. In rare cases, the ABS unit may fail, which will require an expensive replacement (from 20,000 rubles).

On Nissan GT-R And 370Z Ignoring ABS errors can lead to the activation of an “emergency mode” of the engine with power limitation.

FAQ: Frequently asked questions about error C1106

Is it possible to drive with error code C1106?

Technically possible, but not recommended. If there is an error C1106 turns off ABS And VDC, which makes the car less controllable on slippery roads. In addition, brake pad wear increases. If the error appears in winter, fix it as quickly as possible.

How much does an ABS sensor cost for Nissan?

The cost depends on the model:

• Original sensor (For example, 40520-4M000 for Qashqai) - 3000–5000 rubles.
• Analogue (For example, Febi or TRW) - 1500–2500 rubles.
• Used sensor — 800–1500 rubles (risky, since the resource can be exhausted).

For Nissan Patrol And Navara prices are higher - up to 8,000 rubles for the original.

How to reset error C1106 without a scanner?

There are two ways:

1. Disconnect negative battery terminal for 10–15 minutes. This will clear all errors, but if the problem persists, C1106 will appear again.
2. On some models (for example, Nissan Almera N16) you can reset the error by pressing and holding the daily mileage reset button when you turn on the ignition (need to be checked for a specific model).

Why does error code C1106 appear after replacing the wheel bearing?

This is a common problem! Reasons:

• The ABS sensor was damaged when the bearing was pressed out.
• The magnetic ring (encoder) was not transferred to the new bearing.
• The bearing is not installed correctly and the sensor cannot read the signal.

Solution: Check the integrity of the sensor and the presence of a magnetic ring on the new bearing.

Could C1106 be caused by a faulty ABS unit?

Yes, but this happens rarely (about 3% of cases). Typically, a problem in the ABS unit appears along with other errors, for example:

• C1130 - ABS unit malfunction.
• C1140 — communication error with the block.
• U1000 - problems with CAN bus.

If together with C1106 these errors are on, the ABS unit needs to be diagnosed at a service center.
