One of the following fan control modes is selected depending on the heater temperature and
system status.
(1) Stop
(2) 1/2-speed

(4) Full-speed
To detect fan errors, the fan sensor (FANALM-P) is monitored in the full speed mode. The fan
sensor is not monitored for 3 seconds after the start of full speed operation taking into account
the fan sensor output determination time.
The fan sensor is not monitored when the fan is rotating at 1/2 or 1/4 speed or it is at halt.
