Replacing and diagnosing the rear ABS ring on a Nissan Note with drum brakes

Many owners Nissan Note encounter the sudden illumination of the ABS lamp and brake system indicator on the dashboard. Most often, the reason lies not in the sensor itself, but in the magnetic ring, which in this model is located directly on the brake drum. When the ring gear wears out or becomes dirty, the control unit stops receiving the correct signal about the wheel speed, which blocks the operation of the stabilization system.

Rear ring problem ABS on Nissan Note is especially relevant for modifications with drum brakes, since here the element is part of the drum structure, and not a separate part. Ignoring system signals can lead to loss of control on slippery roads, so timely diagnosis and replacement are critical to your safety.

Signs of a malfunctioning magnetic ring

The first and most obvious symptom of a breakdown is the warning light coming on. ABS on the instrument panel. Often the icon lights up along with it. Brake or system indicator VDC (Vehicle Dynamic Control), since all these systems are interconnected.

In some cases, the error may be accompanied by a characteristic sound of the electric motor operating. ABS immediately after starting the engine, even if you do not press the brake pedal. This indicates that the control unit is trying to perform self-diagnosis and is not receiving valid data from one of the rear wheels.

If you notice that the pedal does not vibrate as usual when braking, or the car begins to pull to the side, this may also indicate problems with the speed sensors. Incorrect data from the rear wheel can cause the system to think the wheel is locked and release brake line pressure prematurely.

For accurate diagnosis, it is necessary to read error codes through a diagnostic scanner. Typically the error code indicates a specific wheel, e.g. C1130 or C1135, which means an open circuit or low signal from the rear sensor.

Design features of the rear assembly of Nissan Note

Unlike the front wheels, where the ring is often pressed into the hub, on the rear axle Nissan Note an integrated design is used. The magnetic ring is mounted on the inner surface of the brake drum and is protected from dust and dirt, but may oxidize or become deformed over time.

The main difficulty is that manufacturers do not always offer the ring as a separate element. In most cases, you have to replace the entire brake drum assembled, which significantly increases the cost of repairs, but guarantees the reliability of the unit.

The speed sensor, which reads information from the ring, is located outside and secured with a bolt. It has a plastic tip that is very sensitive to shock and vibration. When removing the drum, it is important to be careful not to damage the sensor element.

Design Feature Nissan Note The first generation is that the rear axle is dependent, and mounting the sensor often requires removing the entire rear beam or significant dismantling of the brake mechanism to access the detachable connections.

Selection of spare parts: original or analogue?

When choosing a replacement part, it is important to understand the difference between the original Nissan and high-quality analogues. Original brake drum with a ring is expensive, but provides ideal tooth geometry and durability.

Analogs from brands like TRW, ATE or Textar may be cheaper, but do not always have an ABS ring included. Sometimes you have to buy a separate ring and try to glue or press it in, which is a risky decision.

• ✅ Original drum number for Nissan Note: 40206-ED000 (check relevance by VIN).
• ✅ High-quality analogues: TRW THD1002, ATE 24.0130-0169.1.
• ✅ Cheap Chinese analogues often have ring play, which leads to false positives of the system.

Step-by-step replacement instructions

Before starting work, it is necessary to securely fix the car on a flat surface and place stops under the front wheels. Remove the wheel from the side where you plan to replace it and unscrew the brake drum guide pins.

Sometimes the drum sticks to the hub due to corrosion. In this case, you should not hit it with a hammer, as you may damage the ring or sensor housing. Use a special puller or carefully pry it through the technological holes.

After removing the drum, carefully inspect the condition of the sensor. If there is any trace of dirt or oil on it, gently wipe it with a rag soaked in brake cleaner. Check the integrity of the wiring going to the sensor.

Installing a new drum occurs in the reverse order. Before putting it on the hub, make sure that the magnetic ring ABS clean and free of metal shavings. Secure the guide pins and install the wheel.

After completing the mechanical part of the work, it is necessary to reset the error in the memory of the control unit. To do this, you can use the OBDII scanner or the reset procedure through the instrument cluster (if provided for your model).

If you are not confident in your abilities, it is better to entrust the work to professionals, as incorrect installation can lead to the drum jamming or the car pulling to the side when braking.

What to do if the drum cannot be removed?

Try using a penetrating lubricant (WD-40) and let it sit for 15-20 minutes. Then gently tap the end of the drum with a rubber mallet, but not along the edge, so as not to damage the work surface.

Features of diagnostics and error reset

After replacing the lamp part ABS may go out immediately if the error was temporary. However, most often a forced reset of error codes is required through the diagnostic connector.

Use a professional scanner or a high-quality multi-brand adapter connected to your laptop or smartphone. Connect the device to the connector OBD-II, which is usually located under the steering column in the area of the fuse box.

⚠️ Attention: Do not try to reset the error by simply disconnecting the battery terminal! This can result in lost settings for the radio, clock, and other systems, and the ABS error is often stored in non-volatile memory.

In the scanner menu, select the “Chassis” section, then “ABS” and find the “Clear Codes” item. After the reset, test drive at a speed of at least 20 km/h to allow the system to reinitialize the sensors.

If the error returns immediately after reset, check the sensor resistance. It should be in the range from 1.0 to 1.5 kOhm (for Nissan). A deviation from the norm indicates a malfunction of the sensor itself or the wiring.

It is also worth checking the gap between the sensor and the ring. In drum brakes, this gap is not adjustable, but if the sensor is damaged or installed crookedly, it may not read the signal. Make sure the connector is firmly seated and free of oxidation.

Technical specifications and compatibility tables

To accurately select a spare part, you need to know not only the car model, but also the year of manufacture and engine type. Below is a table with the main articles for popular modifications Nissan Note.

Model and year	Brake type	Drum part number (Original)	Ring number (if separately)
Nissan Note E11 (2005-2012)	Drum (rear)	40206-ED000	Not sold separately
Nissan Note E12 (2013-2019)	Disc (rear)	40206-3TA0A	40206-3TA0A (in the hub)
Nissan Note E11 (1.4 engine)	Drum (rear)	40206-ED010	Not sold separately
Nissan Note E11 (1.6 engine)	Drum (rear)	40206-ED020	Not sold separately

Please note that rear drum rings are almost never sold separately. This is due to production technology, where a magnetic layer is applied to the metal during the casting or pressing process.

An exception may be rare cases when the ring can be replaced by gluing with special magnetic adhesive, but this method is not recommended by manufacturers and may not pass inspection.

Prevention and care of the ABS system

To extend the life of the stabilization system, regularly clean the area around the rear wheels of dirt and reagents, especially in winter. Accumulation of salt and moisture accelerates corrosion of sensors and wiring.

When replacing rear brake pads, always check the condition of the speed sensor. If it has scuffs or cracks, it is better to replace it immediately while the mechanism is disassembled.

• ✅ Wipe the sensor with alcohol every time you replace the pads.
• ✅ Check the integrity of the insulation of the wires going to the sensor.
• ✅ Make sure that no metal shavings get into the gap between the sensor and the ring.

Regular diagnostics of the ABS system will help avoid sudden breakdowns in critical situations. If you notice even the slightest deviation in the operation of the brakes, do not delay your visit to the service center.

Remember that the ABS system is a complex electronic complex, where the mechanical part is closely connected with the electronics. Any intervention on the brake system requires careful inspection and testing after repair.

⚠️ Attention: After replacing the drum, be sure to check the brake fluid level, as when removing the caliper or drum, it may decrease slightly due to pad wear.

Timely maintenance and the use of high-quality spare parts are the key to the safe operation of your Nissan Note on any roads.

Why does the ABS light come on after replacing the drum?

The lamp may light if the error code has not been reset via the scanner, if the new drum has defects (for example, incorrect ring geometry), or if the sensor was damaged during installation. It is also possible that the sensor connector is not fully latched.

Is it possible to drive with the ABS light on?

Technically it is possible, since the main brakes work, but the stability control and anti-lock braking system will not function. On slippery roads this increases the risk of skidding. It is recommended to eliminate the cause as soon as possible.

How much does it cost to replace an ABS ring on a Nissan Note?

The cost depends on the choice of spare parts. An original drum costs from 8,000 to 15,000 rubles, an analogue one costs from 4,000 to 7,000 rubles. Replacement work takes about 1-2 hours and costs on average 2000-3000 rubles per wheel.

Do I need to replace both rear drums at once?

It is advisable to replace them in pairs, since they have the same wear. If you replace only one, the difference in diameter and characteristics can lead to uneven braking and the car pulling to one side.

How to check the ABS sensor without a scanner?

You can use a multimeter to measure the resistance of the sensor (should be about 1 kOhm). You can also check for the presence of alternating voltage when turning the wheel by hand, but for accurate diagnosis you need a scanner.
