What does the yellow exclamation mark light on the Odyssey mean?

[SanTaylor]

There are many reasons for the yellow exclamation mark light to illuminate in a sedan, such as brake system failure, abnormal tire pressure, lighting system malfunction, etc. The following details the possible causes: Brake system failure: When the brake system warning light remains on, it is likely due to a brake system malfunction or low brake fluid level. When this fault occurs, you should apply greater pressure when braking. The handbrake warning light is similar to the brake system warning light but differs in color—one is red and the other yellow. Abnormal tire pressure: When the tire pressure indicator light remains on, it indicates abnormal pressure in one or more tires. Lighting system malfunction: When the exterior lighting fault light remains on, it indicates a malfunction in the vehicle's exterior lighting system.
