What this warning means
A warning light identifies a system, condition, or protection strategy. It does not authorize a parts replacement by itself.
A warning lamp signals a condition or protection strategy. Its color, behavior, messages, and companion symptoms control urgency.

- 05VerifyFollow the vehicle source and confirm the warning stays resolved
Follow the sequence, stop when evidence changes the path, and verify the exact vehicle information before acting.
Record the exact symbol, color, steady-versus-flashing behavior, messages, and other lamps before clearing evidence.
Safe first checks
Record whether the red brake, traction, or stability lamps are also on.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Note recent tire, hub, brake, battery, or suspension work.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Inspect visible sensor wiring and tire-size/condition differences without disturbing components.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Use a scan tool that can access the brake-control module and follow exact service information.

Safety boundary
Electronic brake-control boundary
ABS and stability systems can require module-specific tests, calibration, or service modes. Do not probe circuits or replace a sensor from the lamp alone.
