The ITOS fault in Great Wall Motors refers to the Intelligent Transmission Oil System malfunction. It is a common problem faced by the owners of Great Wall Haval H6 vehicles that are equipped with a 7-speed dual-clutch automatic transmission system. The fault occurs due to the faulty design of the transmission oil system, which results in the failure of the oil pump, oil pressure regulator, and oil pressure sensor.
Causes of ITOS faultThe primary cause of the ITOS fault is the design flaw in the transmission oil system. The oil pump, oil pressure regulator, and oil pressure sensor are responsible for maintaining the oil pressure and oil flow in the transmission system. Due to their failure, the oil pressure drops, resulting in harsh gear shifts, transmission slips, and failure to engage gears. Other causes of the ITOS fault include a faulty software update, electrical faults, and mechanical problems.
Symptoms of ITOS faultThe most common symptoms of the ITOS fault include slipping gears, engine warning light, sudden jerks or vibrations, and difficulty in shifting gears. The vehicle may also fail to engage gears or may get stuck in a particular gear. The sudden loss of power and acceleration is also an indication of the ITOS fault. If you experience any of these symptoms, it is advisable to seek professional help immediately as it can lead to further damage to the transmission system.
Prevention and SolutionThe best way to prevent the ITOS fault is to ensure timely maintenance and servicing of the vehicle. Regular oil changes, oil filter replacement, and transmission fluid replacement can prevent the failure of the oil pump and oil pressure regulator. If the fault has already occurred, you need to take your vehicle to a skilled mechanic who has experience in handling the ITOS fault. They will diagnose and repair the faulty components and may even recommend a software update to prevent future occurrence of the fault.
In conclusion, the ITOS fault in Great Wall Motors can cause significant problems in the transmission system and affect the performance and safety of the vehicle. Understanding the causes and symptoms of the fault and seeking professional help can prevent further damage and keep your vehicle running smoothly.
ITOS，全称为Intelligent Total Operating System，长城汽车自主研发的智能化总线系统。它可以管理车辆的所有电子控制单元，并且可以实现多种功能，比如实时监测车辆状态、诊断故障、控制车辆的行驶和停止等。
但是，由于该系统涉及许多复杂的硬件、软件和通讯设备，因此存在ITOS故障的可能性。这种故障可能影响车辆的电气系统功能，包括安全系统，如制动器、避免碰撞系统等。所以，如果出现ITOS故障，车辆控制系统可能会失去对驾驶员的控制，从而在行车过程中产生危险。
通常，ITOS故障会导致车辆在车速低于20公里/小时时自动停车，导致紧急情况。此外，车辆的橙色故障灯也会亮起。在发现任何ITOS故障时，驾驶员都应该立即将车辆停靠在安全区域，将发生的故障报告给经销商或汽车维修店。
综上所述，ITOS故障可能对车辆的正常行驶产生严重影响，因此必须定期检查车辆的电气系统以避免该种故障的发生。为了确保汽车的安全行驶，驾驶员在发现任何故障时都应该尽快联系专业人员进行维修，以确保车辆在行驶过程中具有良好的安全性和可靠性。
