Car owners Nissan, equipped with a VDC stabilization system, often encounter the sudden appearance of a warning indicator on the dashboard. Error code C1155 indicates a critical malfunction of the steering angle sensor. This is not just a minor malfunction, but a signal that the electronics have ceased to understand where you intend to turn, which makes the stability control systems and anti-lock brakes impossible.
Ignoring this problem may lead to the fact that in a critical situation the car will not be able to correct its trajectory, which increases the risk of an accident. Owners Nissan Qashqai, X-Trail or Teana It is necessary to quickly understand the nature of the failure in order to avoid costly repairs in the future. In most cases, the problem is solved by calibration, but sometimes the unit itself needs to be replaced.
The essence of the malfunction and the operation of the SABS sensor
Steering angle sensor, often referred to as SAS (Steering Angle Sensor), is one of the key elements of the dynamics control system. It continuously transmits information about at what angle and at what speed the driver turns the steering wheel. The Electronic Control Unit (ECU) uses this data to calculate the required braking force on each wheel separately.
Code C1155 appears when the control unit detects a discrepancy between the signal from the sensor and the actual position of the steering wheel, or when there is no signal at all. This can be caused either by an internal failure of the electronics within the sensor itself, or by a loss of communication via the CAN bus. In some cases, the problem lies in mechanical damage to the steering rack or incorrect installation of the steering wheel after replacing the battery or power failure.
A feature of this malfunction on models Nissan is that the sensor often fails not due to physical wear, but due to a failure of internal calibration. If you recently removed the steering wheel or changed the battery, there is a high probability that the zero reference point was simply violated.
⚠️ Attention: If error C1155 appears, the system VDC is completely disabled, which means there is no skid assist. The driver should be extremely careful on slippery roads.
The main causes of failure C1155
Factors that can trigger the appearance of the code C1155, not so many, but each of them requires a special approach to diagnosis. The most common cause is sensor desynchronization after the car is de-energized or the battery is discharged. In such cases, the sensor loses its “memory” of the zero position of the steering wheel.
Another common cause is a physical malfunction of the sensor itself. Inside the case there is an optical or magnetic element, which over time can become dirty, oxidize, or simply fail due to vibrations. Also, do not rule out problems with the wiring: breaks in the harnesses going from the steering column to the control unit, or poor contact in the connectors.
- 🔋 The battery is completely discharged or the terminals are disconnected without saving the settings.
- 🔧 Poor repair of the steering rack or replacement of steering parts.
- 🌧️ Moisture gets into the connectors of the rotation angle sensor when washing or driving through puddles.
- 💥 Impacts to the front of the car, deforming the steering column.
Diagnostics and verification of the electrical circuit
Before replacing an expensive sensor, it is necessary to thoroughly check the electrical circuits. You will need a diagnostic scanner capable of reading data from the blocks Nissan, and a multimeter. The first step is always to visually inspect the wiring harness and connectors in the steering column area.
You need to make sure that the supply voltage at the sensor is correct (usually 5 volts). If there is no voltage, the problem may be in the fuse or in the control unit itself. Also check the integrity of the signal wires for breaks or short circuits to ground. Often the problem lies in oxidation of the connector contacts, which can be easily eliminated by cleaning and treating with contact spray.
Use diagnostic equipment to view live data. Try slowly turning the steering wheel left and right, observing the changes in the angle readings. If the values fluctuate, do not change, or remain zero when turning, this confirms a sensor malfunction or loss of communication.
⚠️ Attention: Do not try to test the sensor circuit using homemade jumpers or “controls”, as this may damage the sensitive electronic control unit.

Calibration and error reset procedure
If the electrical part is OK and the error is caused by a software calibration failure, the only solution is to train the sensor. This can be done both with the help of professional equipment, and in some cases with improvised means. The process consists of setting the steering wheel to a strictly central position and then resetting the error codes.
On many models Nissan The calibration procedure requires a scanner with "Zero Point Calibration" or "SAS Initialization". Via the OBD-II diagnostic connector you connect to the VDC control unit and start the initialization procedure. Once completed, the steering wheel should be locked straight and then turned to its extreme positions to teach the range.
There is also a “folk” method that helps in some cases, especially after replacing the battery. The essence of the method is to sequentially turn the ignition on and off, as well as turn the steering wheel to extreme positions with pauses. However, this method does not guarantee success and does not work on all modifications.
- 🔌 Connect a professional scanner to the OBD-II connector of the car.
- 🔄 Select the steering angle sensor initialization function from the menu.
- 📍 Make sure the wheels are level on a straight surface.
- 🚗 Start the procedure and wait for the “Success” message from the diagnostic equipment.
☑️ Check before calibration
Replacing the steering angle sensor
When diagnostics confirm physical damage to the sensor, it must be replaced. The steering angle sensor is usually built into the steering column assembly or located directly on it. On some models, for example Nissan X-Trail, it is accessed by removing the steering column cover.
The replacement process requires care since you are working close to the airbag. Be sure to disconnect the negative battery terminal and wait about 10 minutes to allow the capacitors in the SRS system to discharge. After removing the old sensor, install the new one, observing the order in which the connectors are connected.
Even if you install a new node, the error C1155 will remain until the zero point teaching procedure is completed. Therefore, replacement should always be accompanied by software configuration.
⚠️ Attention: When replacing the steering angle sensor, it is strictly forbidden to turn the steering wheel with the battery disconnected or the sensor removed, as this may damage the airbag cable.
How much does it cost to replace a sensor?
The cost of the sensor itself varies from 5,000 to 15,000 rubles, depending on the car model and manufacturer (original or analogue). Replacement and calibration work in the service will cost an additional 2000-4000 rubles.
Nuances of repairs on different Nissan models
Although the principle of operation of the stabilization system is similar on all cars Nissan, there are specific features for different generations and platforms. For example, on a crossover Nissan Qashqai The first generation (J10) sensor often fails due to moisture, since the connector is located at the bottom of the steering column.
On more modern models such as Nissan Murano or Pathfinder, the sensor is integrated into the steering control unit (EPS). In such cases, diagnosis is more difficult, and sometimes the entire steering rack assembly needs to be replaced, which significantly increases the cost of repairs. Also on Nissan Teana J32 there are known cases when error C1155 occurs due to problems with the contact group in the steering column itself.
When making repairs, it is important to consider that some models require a specialized adapter to reset the error. Regular Chinese scanners may not have the SAS initialization function, which forces owners to contact dealerships. On Nissan models with the i-KEY system, the calibration procedure may not complete without the original key being located near the vehicle.
- 🚗 Nissan Qashqai: Check the moisture protection of the sensor connector.
- 🚙 Nissan X-Trail: Pay attention to the airbag cable when dismantling.
- 🏎️ Nissan GT-R: Complex system only requires dealer equipment to reset.
- 🚐 Nissan Serena: Frequent problems with wiring in the steering column area.
Before purchasing a new sensor, be sure to check the catalog number with the original one, since different sensor modifications may be installed for the same model in different years of manufacture.
Prevention and operating tips
To avoid the error reappearing C1155, you must follow simple operating rules. Always monitor the condition of the battery and do not allow it to be deeply discharged, as this is the most common trigger for calibration failure. If you plan to park for a long time, use a charger or disconnect the terminals carefully.
When carrying out any work on the steering column, replacing the airbag or ignition switch, be sure to use a scanner to check error codes before and after repairs. This will help you notice a connection or calibration problem in time, before the system blocks stabilization.
Perform regular maintenance, paying attention to checking the wiring harnesses in the engine compartment and interior. Moisture and corrosion are the main enemies of electronic components. If you notice that the steering wheel has become “wobbly” or the VDC indicators are flashing when turning, do not delay diagnosis.
Regular checking of the battery condition and high-quality calibration after any work on the steering column is the key to the absence of C1155 errors.
