You're cruising along a Malaysian highway, and then a sudden tropical downpour hits. Next thing you know, a message pops up: "Adaptive Cruise Control Unavailable" or "ACC Sensor Blocked." It's a common sight, and usually, it's just a temporary thing. But what if it doesn't come back on after the rain stops? We can help you figure out if it's a simple glitch or something more.
We're equipped to diagnose and support the latest in-car technology, ensuring your drive is safe and predictable.
Your Adaptive Cruise Control relies on a radar sensor, usually in your front grille, to see the car ahead. Here's why heavy rain can disrupt it:
If you've cleaned the sensor and the fault still won't go away in clear weather, it's time for a professional check. If the warning light persists after a restart, it indicates a hard fault. We can check for any visible damage to the sensor or its wiring and use a diagnostic tool to read the specific fault code. If the ACC fault is linked to other warnings (like ABS or traction control), or if your car goes into "limp mode," we can assess its safety and arrange a tow if needed. A faulty ACC sensor often needs recalibration with special equipment, and we can tow your car to a workshop qualified to perform this delicate task.
While a disabled ACC in the rain is often normal, a persistent fault is not. If you're unable to resolve the issue, call us for an expert diagnosis and assistance to ensure all your car's safety systems are running correctly.
