Why are the fault light and ABS light constantly on in the Chery Flagcloud 1?

[HenryLee]

The constant illumination of the fault light and ABS light in the Chery Flagcloud 1 is generally caused by a malfunction in the anti-lock braking system (ABS). The ABS light warning indicates a fault in the ABS system. Reasons for the ABS fault light to illuminate: 1. ABS sensor contamination or damage. Mud or debris inside the ABS sensor signal disc can cause abnormal speed signals. 2. ABS wiring connection issues. ABS wiring may be chewed through by rodents, most commonly in the front wheel liner or around the rear fuel tank area. 3. ABS control unit (ECU) malfunction. 4. Faults in the sensor hub signal disc or master cylinder. 5. ECU circuit board issues, often due to poor component contact. 6. Aging ABS master cylinder or poor contact in ABS master cylinder or power connectors. Solutions for ABS fault light illumination: The ABS warning light can be triggered by various factors. If the ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, it may affect the sensor's ability to detect speed signals, preventing the ABS computer from determining the vehicle's speed and issuing appropriate braking commands. In such cases, simply cleaning the sensor and adjusting its gap with the signal ring can restore normal function. If the speed sensor is damaged, it must be replaced. Additionally, loose ABS wiring connections or internal ABS pump failures can also cause the ABS light to illuminate, requiring a comprehensive inspection to resolve the issue.

It's not uncommon for long-time drivers to encounter situations where the Chery Flagcloud's malfunction indicator light and ABS light stay on constantly. More often than not, this is caused by issues with the wheel speed sensors, such as contamination from mud or loose wiring connections, leading to false signal reports from the system. The ABS light being on indicates a fault in the anti-lock braking system, making wheels prone to locking during emergency braking, which is very dangerous. Simultaneous illumination of the malfunction light may be related to engine-associated sensors, such as a faulty oxygen sensor. I recommend immediately using an OBD scanner to read the fault codes and pinpoint the cause without delaying driving, as ABS failure increases the risk of accidents. For a simple self-check, you can inspect whether the sensor connectors near the wheel hubs are secure, but most cases require professional shop attention. Remember to rinse the undercarriage during maintenance to keep sensors clean and avoid similar troubles.

A friend's car had the same issue before—the check engine light and ABS light staying on is something to take seriously. It's often caused by a dirty or water-damaged wheel speed sensor, as the ABS system relies on it to measure wheel rotation for anti-lock braking. When these lights stay on, it means the system isn't functioning properly, making emergency braking unsafe; the engine light might also indicate other problems. You can check if the sensor connector is loose and try cleaning it yourself, but it's best to use an OBD scanner to read the trouble codes and identify the faulty part before heading to the repair shop. Don't push through driving with the issue—it increases the risk of accidents. During routine maintenance, inspect the wiring condition to prevent minor issues from escalating.

Safety first, don't ignore the constant illumination of the malfunction indicator light and ABS light. ABS failure may cause wheel lock-up and loss of vehicle control during emergency braking; meanwhile, the engine light may indicate an air-fuel ratio issue. Typically, dirty wheel speed sensors triggering false alarms are the main cause. In such cases, promptly visit a professional shop for OBD diagnosis and repair. If lights illuminate while driving, reduce speed and avoid sudden braking. For prevention, pay more attention to keeping the sensor area clean.

Don't panic when this car issue occurs, start with the basics: Check if the ABS sensor wires and connectors inside the wheel hub are loose or dirty, gently wipe them with a soft cloth; but avoid tampering with the wiring to prevent further damage. Most of the time, minor sensor malfunctions cause both warning lights to illuminate—it's recommended to use an onboard diagnostic tool to read the error codes and pinpoint the cause before repairs. ABS failure poses significant risks, so address it promptly. Regularly rinse the undercarriage during car washes to prevent dust buildup.

Maintaining your car is crucial. The fault light and ABS light on the Chery Flagcloud often illuminate due to aging wheel speed sensors or wiring. Prevention is key: remind technicians to check the cleanliness of the sensor area during maintenance to avoid rust after parking on wet roads. When the light comes on, use an OBD scanner to quickly and affordably diagnose the issue, as an unreliable ABS increases accident risks. If the light turns on while driving, reduce the frequency of sudden braking. Installing sensor covers can also help.
