On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or "idiot light" if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.
Off with your head
Dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Glitter on the wet streets
Silver over everything
The river's all wet
You're all cold
Dripping with alchemy
Shiver stop shivering
The glitter's all wet
You're all chrome
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
Oh, oh, oh, oh
Off, off with your head
Dance, dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Looking glass, take the past
Shut your eyes, you realize
Looking glass, take the past
Shut your eyes, you realize
Glitter on the wet streets
Silver over everything
The glitter's all wet
You're all chrome, you're all chrome
Oh, oh, oh
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
