K62 Abs and ebd warning lights both on
During starting, the "ABS" and "handbrake" warning lights come on simultaneously and stay on for over 4 seconds. (after the initial test on the control unit, both warning lights should go out)
NOTA: The "low brake fluid" and "handbrake on" warning light, if it comes on together with the "ABS" warning light, indicates a fault in the function
NOTA: Under these conditions, when the brakes are operated, the rear wheels may lock and the car may skid, as the system's EBD function is temporarily deactivated
NOTA: If it comes on by itself, this means that the handbrake is on or that the brake fluid level is low
