Half credit Phil :-)
The autocheck and ECU/CC head signals are separate. The autocheck
signal is at a higher temperature, at least on the mechanical version
of the sensor(wax piston actuator, thermocouple disk).
Also, nobody has mentioned that low coolant will cause the same
warning; they're on the exact same circuit.
