How to eliminate the flashing AFS light on an old Camry?

AFS OFF light indicates that the headlight's adaptive front-lighting system (AFS) is turned off. Press the switch button located above the brake pedal to activate the intelligent adaptive front-lighting system. Inspect the AFS module, use a decoder to match and set the system, and clear the fault code to eliminate the AFS warning light. Disconnect the headlight power supply, ensure the vehicle's power is off, then open the engine hood, locate the battery's negative terminal, disconnect and reconnect it.

When the AFS light on my old Camry flashes, I looked it up and found that it indicates a fault in the adaptive headlight system. Focus on checking three areas: whether the steering module in the headlight assembly has poor contact, if the wiring of the rear axle vehicle height sensor is aged or broken, and also inspect the connection of the steering wheel angle sensor. Last time, I discovered that the sensor connector was corroded—after cleaning the connector and resetting the system with a diagnostic tool, it worked fine. If you can't fix it yourself, spending some money to have a repair shop connect a computer to read the fault codes is the most hassle-free solution. Don't push through it; the flashing light means the illumination angle during turns might be uncontrolled, which is quite dangerous when driving at night.

The AFS light flashing issue with the Camry is quite common, I've encountered it several times. First, open the engine hood to check the wiring harness near the headlights. On older cars, the rubber insulation tends to deteriorate, making it prone to peeling and short circuits. Then, get under the car to inspect the height sensor. The metal plate on it can easily get clogged with mud, causing signal errors. A simple fix is to remove the sensor and clean it with WD40. Last time at the repair shop, I saw the mechanic replace the sensor and then use professional equipment to recalibrate and reset it. If you're handy, you can buy an OBD scanner yourself—just over a hundred bucks, and you can connect it to your phone to clear the fault codes. When washing your car, pay attention to rinsing the undercarriage, as excessive mud and sand can easily trigger this problem.

The flashing AFS light on older Toyotas is usually a sensor issue. Here's how I fixed it myself: Turn off the engine, remove the key, wait 5 minutes, then restart to let the system self-check. If the light still flashes, inspect the AFS-related fuses in the fuse box. Next, turn the steering wheel fully left and right once each to reset the steering sensor. If that doesn't work, check the small square sensor on the rear suspension - it's prone to moisture errors during rainy seasons. I recommend avoiding tinkering in humid weather; wait for a sunny day for safer disassembly. Don't randomly unplug connectors as wiring in older cars is quite fragile.
