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
