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.
- 01IdentifyABS · assess urgency
- 02AssessDrive cautiously only when braking feels normal and the vehicle manual permits it; preserve the warning state and arrange a scan of the brake-control system.
- 03PreserveWhich lamps are on / Wheel/tire changes
- 04CheckRecord whether the red brake, traction, or stability lamps are also on. / Note recent tire, hub, brake, battery, or suspension work.
- 05VerifyFollow the vehicle source and confirm the warning stays resolved
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.

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.
