Actuator Check

WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

ACTUATOR CHECK

After entering the sensor check mode, press the R/F switch.

Since each damper, motor and relay automatically operates at 1 second intervals beginning in order from 20 in the temperature display, check the temperature and air flow visually and manually.

If a slower display is desired, press the DEF switch and change it to step operation. Every time the DEF switch is pressed, the display changes by 1 step.

HINT:

The buzzer sounds when the display trouble code changes.
Codes are displayed in order from the smaller to the larger numbers.
To cancel the check mode, press the OFF switch.
