Error with code 13533 AU000 - one of the most mysterious malfunctions that owners encounter Nissan Qashqai, X-Trail, Juke and other models of the brand. It does not have a universal description in standard diagnostic systems, which often misleads car owners and even some technicians. Unlike typical engine or transmission errors, this code can indicate either electronic or mechanical problems, depending on the context in which it appears.

In this article we will look at all possible reasons errors 13533 AU000 is specific to Nissan multiplex CAN bus systems and is often associated with a conflict between ECU modules due to incorrect firmware updates or physical damage to the wiring., methods for diagnosing it (including scanners Launch X431, Bosch KTS and even budget adapters ELM327), as well as step-by-step troubleshooting instructions. We will pay special attention to the nuances that even experienced masters ignore - for example, the influence U1000 for the appearance 13533 or hidden failures in the block BCM after a battery emergency shutdown.

What does code 13533 AU000 mean in Nissan?

Code 13533 AU000 not standard OBD-II-code and refers to Nissan manufacturing errors. The official documentation describes it extremely vaguely: “Malfunction in the communication system between electronic modules" In practice this could mean:

  • 🔌 Lost connection between blocks ECU (For example, Engine Control Module And Transmission Control Module).
  • 🔄 Firmware conflict after updating the software via Nissan Consult-III or unofficial tools.
  • ⚡ Short circuit in the tire CANcaused by damaged wiring or oxidation of contacts.
  • 🔧 Module incompatibility when replacing units (for example, installing BCM from another model).

It is important to understand that 13533 AU000 - this is not the root cause, but consequence other malfunction. For example, if the system already has an error U1000 (loss of connection with ECM), then after some time it may appear 13533. Ignoring this code may cause the vehicle to go into emergency mode with power limitation or complete blocking of engine starting.

📊 Which Nissan model are you experiencing error 13533 AU000 with?
  • Qashqai (J10/J11)
  • X-Trail (T31/T32)
  • Juke (F15)
  • Other model

The main reasons for the error

Forum analysis (Drive2, Nissan Club Russia) and data from diagnostic centers shows that 13533 AU000 occurs in five key scenarios:

  1. Firmware update with interruption. If the update process ECU through Nissan Consult was interrupted (for example due to a power failure), the modules may lose synchronization. This is especially true for cars with a system NissanConnect.
  2. Tire damage CAN. Most often, the contacts in the connectors under the steering wheel or near the fuse box are affected. Oxidation or broken wires CAN-H And CAN-L leads to loss of communication between modules.
  3. Incompatible spare parts. Installation of used blocks ECU, BCM or TCM without reference to VIN-car number.
  4. Block failures BCM. This module controls the “body” of the car (lighting, power windows, central locking). If it malfunctions, other blocks may “freeze” and generate 13533.
  5. Battery problems. Sudden voltage surges (for example, when lighting a cigarette) or deep battery discharge often lead to memory failures ECU.

Interesting fact: on Nissan Qashqai J11 (2014–2021) error 13533 AU000 often appears after replacing the radio with a non-standard one. This is due to the fact that the new head unit begins to conflict with BCM via bus MOST, which in these models is integrated with CAN.

Details about the CAN bus in Nissan

The CAN (Controller Area Network) bus in Nissan consists of two wires: CAN-H (high level) and CAN-L (low level). The normal voltage between them is about 2.5V when the ignition is off and 3.5–4.5V when it is on. If the difference exceeds 1V or falls below 0.5V, the blocks stop “seeing” each other, which leads to error 13533 AU000.

How to diagnose error 13533 AU000?

For accurate diagnostics, you will need a scanner that supports Nissan production protocols. Suitable:

  • 🔧 Launch X431 V+ (with program Nissan).
  • 🔌 Bosch KTS 570/590.
  • 💻 Nissan Consult-III/IV (official dealer scanner).
  • 📱 Budget adapters ELM327 (only for reading codes, without in-depth diagnostics).

Diagnostic algorithm:

  1. Connect the scanner and check all errors, and not just 13533. They often go with him U1000, U1010 or B2606 (malfunction BCM).
  2. Check bus voltage CAN (see spoiler above). To do this:
    3. 1. Выключите зажигание.

    2. Подключите мультиметр к контактам CAN-H и CAN-L (обычно в диагностическом разъёме OBD-II это контакты 6 и 14).
    

    3. Норма: 2.5В ± 0.5В.

  3. Test the circuit for opens and short circuits. Pay special attention to the connectors under the steering column and the fuse box.
  4. Check the firmware version ECU And BCM. If they are incompatible, flashing will be required.

☑️ Checklist before diagnosis

Done: 0 / 4

⚠️ Attention: If the scanner shows an error during diagnostics U1000 along with 13533 AU000, first eliminate U1000 — it blocks communication between modules and makes further diagnostics impossible.

Step-by-step instructions for resolving the error

Depending on the cause, repair methods will vary. Below is a universal algorithm that covers 80% of cases.

1. Reset errors and reboot the system

Sometimes it's a mistake 13533 AU000 appears due to a temporary glitch. Try:

  1. Clear errors via scanner.
  2. Disconnect the battery for 10–15 minutes (remove the negative terminal).
  3. Reconnect the battery and start the engine.
  4. Check if the error returns.

2. Checking and repairing the CAN bus

If the error remains, inspect the wiring:

  • 🔍 Check the contacts in the connectors OBD-II, under the steering wheel and near the fuse box.
  • 🔧 Clean oxidized contacts (use WD-40 or special lubricant for electrical contacts).
  • 📏 Ring the wires CAN-H And CAN-L for a break with a multimeter.

⚠️ Attention: If, when checking the resistance between CAN-H And CAN-L multimeter shows 0 ohm - there is a short circuit in the bus. If the resistance is higher 120 Ohm - break. Norm: 60–65 Ohm.

3. Updating or rolling back ECU/BCM firmware

If the problem is software:

  1. Download the latest firmware for your model on the website Nissan TechInfo (subscription required).
  2. Connect Nissan Consult-III or Launch X431.
  3. Follow the update instructions (do not interrupt the process!).
💡

Before flashing ECU be sure to check the voltage of the on-board network - it must be at least 13.5V. Use a power supply instead of a battery to avoid malfunctions.

4. Replacing faulty modules

If none of the methods helped, one of the blocks may have failed:

Module Symptoms of a problem Cost of a new one (approx.)
ECU (Engine Control Module) Engine does not start, errors P0600–P0606 20 000–50 000 ₽
BCM (Body Control Module) Power windows, lighting, central locking do not work 15 000–35 000 ₽
TCM (Transmission Control Module) Jerks when shifting gears, errors P0700–P0799 18 000–45 000 ₽
IPDM (Intelligent Power Distribution Module) Fans, headlights, heated seats do not work 25 000–60 000 ₽

⚠️ Attention: When replacing blocks ECU/BCM be sure to follow the procedure binding to VIN through Nissan Consult. Without this, the car will not start or will not work properly.

Common mistakes during repairs

Many car owners and even mechanics make critical mistakes when trying to fix 13533 AU000. That's what can't do:

  • 🚫 Reset errors without diagnostics. This only masks the problem, but does not eliminate it. After a while, the error will return, and new ones may appear along with it (for example, U1000 or B2606).
  • 🚫 Use unofficial firmware. Firmware from torrents or dubious sites can “kill” ECU forever. Download official software only from Nissan TechInfo.
  • 🚫 Change blocks without reference to VIN. Even if you install a new one BCM from the same model, without binding it will not work.
  • 🚫 Ignore errors U1000 And U1010. They often go along with 13533 and indicate problems with the tire CAN. Eliminate them first.

Another common mistake is trying to “treat” 13533 AU000 replacing fuses. Fuses protect circuits from short circuits, but do not affect software glitches or bus problems CAN. If a fuse is blown, look for the cause (for example, a short in the wiring) rather than simply installing a new one.

💡

If after resetting the errors 13533 AU000 appears again within 5-10 minutes - the problem is definitely in the hardware (wiring, blocks), and not in the software.

Prevention of error 13533 AU000

To avoid this error, follow these simple rules:

  • 🔋 Monitor the voltage of the on-board network. Sudden jumps (for example, when “lighting up”) can damage memory ECU. Use a voltage stabilizer.
  • 🔌 Check your contacts regularly. Clean the connectors once a year CAN-tires and diagnostic port from oxidation.
  • 📱 Update firmware only using official methods. No “homemade” firmware or interrupted updates.
  • 🚗 Avoid non-standard electronics. Cheap alarms, radios and LED lighting often conflict with CAN- tire.

If you plan to install additional equipment (for example, a rear view camera or parking sensors), connect it via special adaptersthat do not disrupt operation CAN-tires. For example, for Nissan Qashqai J11 adapter will do CanBus Interface from Connects2.

FAQ: Frequently asked questions regarding error 13533 AU000

Is it possible to drive with error 13533 AU000?

Technically possible, but not recommended. The error indicates problems with communication between control units, which can lead to:

  • Unpredictable engine behavior (jerking, loss of power).
  • Failure of security systems (ABS, ESP).
  • Complete blocking of engine starting (if the error reaches a critical stage).

If the error appeared recently and is not accompanied by other symptoms, you can go to the service center. But if they burn with her Check Engine or ABS, it is better to call a tow truck.

How much does it cost to repair error 13533 AU000 in the service?

The cost depends on the reason:

  • Diagnostics: 1 500–3 000 ₽.
  • Wiring repair CAN: 3,000–8,000 RUR (depending on complexity).
  • Flashing ECU/BCM: 5 000–15 000 ₽.
  • Replacing the block BCM: 20,000–50,000 ₽ (with work and binding).

At dealerships, prices are 30–50% higher, but they guarantee original spare parts and correct connection of the blocks.

Is it possible to reset error 13533 AU000 without a scanner?

Technically yes, but this is a temporary solution. Methods:

  1. Disconnect the battery terminal for 10–15 minutes (sometimes it helps with temporary failures).
  2. On some models (for example, Nissan Juke) you can reset errors via service menu: 
    1. Выключите зажигание.

    2. Нажмите и удерживайте кнопку сброса суточного пробега.
    

    3. Поверните ключ в положение ON (не запуская двигатель).
    

    4. Удерживайте кнопку 10 секунд, пока не появится сервисное меню.
    

    5. Найдите пункт "Clear DTC" и подтвердите сброс.

However, without eliminating the cause, the error will return.

Why does error 13533 AU000 appear after replacing the battery?

When the battery is disconnected, some units (ECU, BCM) lose settings and may conflict when restarted. To avoid the problem:

  • Use buffer power supply (For example, NOCO GB40) to maintain voltage when replacing the battery.
  • After connecting a new battery do not start the engine immediately — let the units initialize (wait 1–2 minutes with the ignition on).
  • If an error appears, perform a reset via the scanner or service menu.
Could error 13533 AU000 be caused by an alarm?

Yes, and this is one of the most common reasons. Cheap alarms (for example, StarLine or Pandora in the budget package) are connected to CAN-bus and can:

  • Create interference in the bus due to poor wire insulation.
  • Conflict with blocks ECU/BCM due to incorrect commands.
  • Cause errors U1000 And 13533 upon activation/deactivation.

Solution: Turn off the alarm and check if the error goes away. If yes, contact your installer for proper configuration or replacement of the module CAN adapter.
