What does it mean when the EPC light stays on?

If the vehicle's EPC light stays on, it indicates a malfunction in the internal system or components. The EPC indicator light can illuminate in two scenarios: during the power-on self-test or under other conditions. The power-on self-test is a pre-driving check of all vehicle sensors. Typically, if the engine is not started after power-on, the light will turn off by itself after about 3 seconds. If the EPC light remains on under other conditions or does not turn off for an extended period after the vehicle starts, the main causes for the EPC light staying on include faults in the engine intake system, throttle body, fuel system, engine, ECU control unit, or brake lights. Below is a detailed explanation of the reasons for the EPC light staying on under other conditions: Engine intake system fault: The EPC light will illuminate if the engine intake is obstructed or insufficient. Throttle body fault: Carbon buildup is a common issue with the throttle body. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Issues such as substandard fuel, fuel deterioration, or poor fuel atomization can cause this. Engine fault: Insufficient engine pressure or problems with components like the intake valves can also activate the EPC light. ECU control unit fault: For example, interference with the vehicle computer signals or false alarms from the computer. Brake light fault: This includes situations like brake lights not working, faulty brake switches, or brake circuit issues. Solutions for when the EPC light illuminates: Troubleshoot the intake system, use the appropriate fuel grade, clean the throttle body, etc. Remove carbon deposits from relevant parts. Re-flash the ECU data. If the EPC light comes on, the driver can first try turning off the engine and restarting it to see if the EPC light remains off. If it does not come back on, there may be no issue, and the light could have been triggered by external factors. However, if the EPC light stays on or frequently illuminates, the vehicle should be taken to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data deviates from normal values, the EPC system takes predefined actions to adjust the powertrain. Common EPC indicator lights are displayed in two colors: yellow and red. A yellow EPC fault light indicates that the vehicle can still be driven but should proceed slowly to a repair point. A red EPC fault light signifies a more severe issue, requiring immediate roadside parking and contacting a repair service. Continuing to drive with a red EPC light can damage core components or compromise driving safety.

Should You Replace Two Tires or All Four at Once?

You can choose to replace either two tires or all four at once, but if conditions permit, it is recommended to replace all four tires simultaneously to maintain the original handling balance. Tires on the same axle should be of the same specification, structure, manufacturer, and tread pattern. If only two tires are being replaced, it is advisable to install the new tires on the rear wheels. If only one tire is being replaced, the new tire must have a tread groove depth similar to that of the other tire on the same axle; otherwise, it may cause issues such as vehicle pulling. Methods to determine whether tires need replacement are as follows: 1. Severe wear: Each tire tread groove has a wear limit indicator, which is approximately 2mm thick. It is recommended to replace the tires when the tread thickness wears to 4mm from the limit indicator, or about 6mm from the deepest part of the groove. 2. Severe aging: Observe the patterns on the tire tread and sidewalls. If cracks are widespread, it indicates severe tire aging. Even if the mileage is low or the usage time is short, the tires should be replaced promptly. Otherwise, the weakened sidewall strength of aged tires increases the risk of blowouts during high-speed driving due to rising temperatures. 3. Frequent repairs: One or two tire repairs will not affect tire usage, but after more than three repairs, it is recommended to replace the tires for safety reasons. During high-speed driving, the internal temperature of the tire rises, and although the damage has been repaired, the risk of failure still increases. 4. Bulging or deformation: Bulging or deformation of a tire is very dangerous. If such issues are found, it is best to have them inspected and handled by a professional repair shop immediately. In most cases, tire replacement is recommended. Such issues indicate that the internal metal coils of the tire have deformed or broken, and continuing to drive poses a high risk of blowouts. 5. Punctured sidewall: A punctured sidewall is indeed more dangerous than a damaged tread. If the damage is located below the indicator near the wheel rim edge, the tire must be replaced because the steel wire strength in this area is very weak, and the repair process will inevitably subject it to squeezing and deformation, making it difficult to ensure the repair's effectiveness.
