U0104 Code Nissan:
The U0104 code in a Nissan indicates that there is a communication problem between the vehicle’s engine control module (ECM) and the advanced driver assistance systems control module (ADAS). This can cause issues with the vehicle’s safety features, such as the lane departure warning system, adaptive cruise control, and automatic emergency braking.
The most common cause of this code is a faulty ADAS control module, which may need to be replaced. However, it is also possible that there is a wiring issue or a problem with the ECM. A diagnostic scan tool can be used to identify the exact cause of the communication failure.
To fix the U0104 code, the underlying issue must be addressed. This may involve replacing the ADAS control module, repairing damaged wiring, or replacing the ECM. It is important to have this issue resolved as soon as possible to ensure the vehicle’s safety features are functioning properly.
Signs and Symptoms of U0104 Code in Nissan
The U0104 code in Nissan indicates that there is a communication problem between the Engine Control Module (ECM) and the Advanced Driver Assistance Systems Control Module (ADAS). This code is usually accompanied by a Check Engine Light (CEL) on the dashboard. Here are some of the common signs and symptoms of the U0104 code in Nissan:
- CEL Illumination: The most common symptom of the U0104 code is the illumination of the Check Engine Light on the dashboard. This light indicates that there is a problem with the engine or the vehicle’s systems.
- Reduced Performance: Another symptom of the U0104 code is reduced performance of the vehicle. The engine may not run as smoothly as it should, and there may be a decrease in power and acceleration.
- Transmission Problems: The U0104 code can also cause transmission problems. The transmission may shift roughly or may not shift at all. This can lead to a jerky ride and can be dangerous if the vehicle is not able to shift gears properly.
- Stalling: In some cases, the U0104 code can cause the engine to stall. This can happen when the vehicle is idling or when it is in motion. Stalling can be dangerous, especially if it happens while the vehicle is in motion.
- Difficulty Starting: The U0104 code can also cause difficulty starting the engine. The engine may crank but not start, or it may take longer than usual to start.
- Other Codes: The U0104 code can also cause other codes to appear on the dashboard. These codes may be related to the transmission, the engine, or other systems in the vehicle.
If you notice any of these symptoms in your Nissan, it is important to have the vehicle diagnosed by a qualified mechanic. Ignoring the U0104 code can lead to further damage to the vehicle and can be dangerous if the vehicle is not able to operate properly.
Possible Causes of U0104 Code in Nissan
The U0104 code in Nissan indicates that there is a communication problem between the Engine Control Module (ECM) and the Advanced Driver Assistance Systems Control Module (ADAS). This code is usually triggered when the ECM fails to receive signals from the ADAS module. Here are some of the possible causes of the U0104 code in Nissan:
- Failed ADAS Control Module: The ADAS control module is responsible for controlling various safety features in the vehicle, such as lane departure warning, adaptive cruise control, and automatic emergency braking. If this module fails, it can cause a communication problem with the ECM, triggering the U0104 code.
- Wiring Issues: Faulty wiring or loose connections between the ADAS module and the ECM can also cause the U0104 code. This can happen due to wear and tear, corrosion, or accidental damage to the wiring harness.
- ECM Malfunction: In some cases, the U0104 code can be triggered due to a malfunctioning ECM. This can happen if the ECM is damaged or has a software glitch that prevents it from communicating with the ADAS module.
- Low Battery Voltage: The U0104 code can also be triggered if the battery voltage is low. This can happen if the battery is old, weak, or has a faulty charging system. Low battery voltage can cause communication problems between various modules in the vehicle, including the ECM and ADAS module.
- Software Issues: Sometimes, the U0104 code can be triggered due to software issues in the ADAS module or ECM. This can happen if there is a bug in the software or if the module needs to be reprogrammed.
If you are experiencing the U0104 code in your Nissan, it is important to get it diagnosed and repaired as soon as possible. Ignoring this code can lead to safety issues and can also cause other problems in the vehicle. A qualified mechanic can diagnose the problem and recommend the appropriate repairs.
