C0040 on Chevrolet
Right front wheel speed sensor circuit (GM) or brake lamp switch (Honda)
Severity: Inspect soon
On GM, Saab service information says the brake module then switches off ABS, traction and stability control for the ignition cycle; a Honda owner reports hot brakes from a stuck brake switch.
It gets more serious if:
- Stop: Stop and have it inspected if the red BRAKE light is on, the brake pedal feels different, or a wheel smells hot or smokes.
