How to eliminate the light fault indicator?

Methods to eliminate the light fault indicator: 1. If the brake system fault light is on, it needs to be repaired at a maintenance shop to eliminate it; 2. If the oil pressure fault light is on, adding engine oil will eliminate it. If the fault light does not go away after adding oil, call the 4S shop for maintenance; 3. If the water temperature warning light is on, adding coolant or pure water will eliminate it; 4. If the ABS fault light and engine fault light are on, the indicator light will automatically turn off after maintenance and starting the car. The car fault light is a fault display light. If the vehicle has certain faults, the corresponding light will turn on.
When the light fault indicator comes on, I find the most practical approach is to first conduct a DIY inspection. For instance, after turning off the engine, pop the hood and check all exterior bulbs for burnout or looseness—focusing on high-risk areas like taillights, brake lights, and headlights. Replace any faulty bulbs, restart the vehicle, and often the warning light will reset after driving a few kilometers. If it persists, suspect poor wiring contact or a short circuit—inspect connectors and the fuse box for irregularities. Having encountered this myself, methodical troubleshooting usually resolves it. Skipping the repair shop saves time and money. Remember to routinely inspect lighting systems to prevent nighttime hazards, ensuring roadworthiness before driving.
As someone who frequently helps others with car repairs, the key to eliminating the lighting malfunction indicator is to fix the root issue and reset the system. The first step is diagnosing the source of the problem: use an OBD scanner to read the error codes and confirm whether it's a headlight failure, wiring short circuit, or control module malfunction. After repairs, such as replacing bulbs or connectors, some vehicles will clear the warning light by simply turning off and restarting the engine. If that doesn't work, disconnect the battery's negative terminal for over 5 minutes to clear the system's memory. To prevent recurrence, check the vehicle's voltage stability and lighting relays, and avoid improper operations when modifying wiring. These steps ensure the light goes off only when the problem is truly resolved—don't delay to avoid compromising driving safety. Always wear protective gloves during operations to prevent electric shock.
