Consequence of non-compliance: There would be no indication to the driver of the vehicle that brake fluid was low. Low brake fluid can be caused by a leak in the system which may result in partial or complete loss of brakes and an accident.
Service Brakes, Hydraulic — Brake Fluid Low Warning — Lamp
The instrument panel brake warning light will not illuminate when the brake fluid level in the master cylinder drops sufficiently to activate the low level switch due to an improperly wired diode, required by FMVSS no. 105, "hydraulic brake systems."
Dealers will correct the electrical circuit for the brake warning system so that the warning lamp will illuminate when the low level switch is activated.
