Fail-safe
INFOID:0000000012200024
FAIL-SAFE FUNCTION
If a communication error exists between the A/C auto amp. and multi display unit for 2 seconds or longer, air
conditioning is controlled under the following conditions:
DTC Index
INFOID:0000000012200025
*: Perform self-diagnosis under sunshine. When performing indoors, aim a light (more than 60 W) at sunload
sensor, otherwise self-diagnosis indicates even though the sunload sensor is functioning normally.
A/C display
: OFF
Set temperature
: Setting before communication error occurs
Air outlet
: Automatic control
Air flow
: Automatic control
Air inlet
: Fresh air intake (FRE)
A/C switch
: ON
