ABS AND HANDBRAKE WARNING LIGHTS BOTH ON
With the ignition, the ABS warning light and the handbrake warning light come on simultaneously and stay on for longer than 3 seconds (both warning lights should go off after the initial control unit test)
The low brake fluid level and handbrake warning light also indicates an EBD fault if it comes on at the same time as the ABS warning light
Under these circumstances, the rear wheels may lock and the vehicle may skid if the brakes are operated because the system EBD function is temporarily deactivated. If it comes on by itself, this means that the handbrake is on or the brake fluid level is too low
