Repair of ABS brake system faults requires targeted measures based on specific causes. Common issues include dirty or damaged wheel speed sensors, abnormal signal wheels, circuit breaks or loose plug connections, and control unit malfunctions. First, diagnostic equipment should be used to read fault codes. If the sensor is dirty, it needs to be cleaned or the gap adjusted (the standard value is usually 0.3-1.0mm); if the sensor is damaged, it needs to be replaced, costing approximately 300-800 Malaysian Ringgit. For circuit problems, wire connections and fuses should be checked. If the ABS control unit is damaged, the repair cost may reach 2000-4000 Malaysian Ringgit. Additionally, the brake fluid level should be checked (if it is below the MIN mark, DOT4-compliant brake fluid needs to be added) and the power supply voltage (if it is below 10.5V, the system will shut down). Notably, using non-OEM specification tyres or incorrect tyre pressure can also cause speed signal deviation, triggering the ABS warning light. If the warning light persists, professional repair services should be promptly contacted for diagnosis. While ABS failure doesn't affect basic braking functionality, it increases the risk of wheel lock-up on slippery surfaces.
