DTC CHECK (SENSOR CHECK)







a. Perform an indicator check. After the indicator check is completed, the system enters the DTC check mode automatically.
b. Read the code displayed on the panel. Refer to the list of codes when reading the trouble codes. (Trouble codes are output at the driver side temperature display.)

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









HINT:
- If the buzzer sounds when a trouble code is being read, it means the trouble indicated by that trouble code continues to occur.
- If the buzzer does not sound when a trouble code is being read, it means the trouble indicated by that trouble code occurred earlier (such as poor connector contacts, etc.).
