[s-cars] ABS shutting down

[Robin Stoddard]

Hey Calvin,

I would have been driving the car around (no lights would come on), stop
the car (turn off the motor and buy a coffee), start the car back up,
the warning lights will be on.  Even if I stay parked (motor running) or
drive around, the lights will not go out.  It's only when I shut the car
off and let it cool down (hood open) for at least 30 minutes, then the
system is back to normal when I restart the engine.

Thanks again
Robin
