How is the ABS system check described?

• A. The ABS warning light should stay on continuously if functioning properly
• B. The ABS warning light should never appear at startup
• C. Light appears 1-3 seconds at startup; no light = possible malfunction; stays on = possibly inoperable
• D. The ABS warning light should flash twice per minute

Answer: (C)

Understanding how the ABS warning light behaves during ignition self-check is tested here. When you turn the ignition on, the ABS system runs a quick self-diagnostic. The normal sequence is for the warning lamp to illuminate for a brief period—about one to three seconds—and then go out, confirming the system and its self-check passed. If the light does not come on at all, that can indicate a fault in the warning circuit or a burned-out bulb. If the light stays on after starting, that signals a fault within the ABS system and the system may be inoperable. Therefore, the described behavior—a brief light at startup, no light implying a potential issue, and a light that remains on indicating a fault—best describes how the ABS system check is described. The other patterns (light staying on continuously as normal, never appearing at startup as normal, or flashing in a specific on/off pattern) do not match typical ABS self-check behavior.
