CONSULT-III performs the following functions via CAN communication with A/C auto amp.

Diagnostic mode
Description
Self diagnostic result
Displays the diagnosis results judged by A/C auto amp.
Data monitor
Displays the input/output signal of A/C auto amp.
Active test
The signals used to activate each device are forcibly supplied from A/C auto amp.
Work support
Changes the setting for each setting function.
  • Temperature setting trimmer
  • Inlet port memory function (FRE)
  • Inlet port memory function (REC)
  • Foot position setting trimmer
ECU identification
Displays the part number of A/C auto amp.

NOTE:
Diagnosis should be performed with engine running. Door motor operation speeds become slower and NO results may be returned even for normal operation if battery voltage drops below 12 V during self-diagnosis.
 
 SELF-DIAGNOSIS RESULTS

Refer to DTC Index.

 WORK SUPPORT

Work item
Description
Refer to
TEMP SET CORRECT
(Temperature setting trimmer)
If the temperature felt by the customer is different than the air flow temperature controlled by the temperature setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.
Temperature Setting Trimmer
FRE MEMORY SET
[Inlet port memory function (FRE)]
  • If the ignition switch is turned to the OFF position while the FRE switch is set to ON (fresh air intake), “Perform the memory” or “Do not perform the memory” of FRE switch ON (fresh air intake) condition can be selected.
  • If “Perform the memory” was set, the FRE switch will be ON (fresh air intake) when turning the ignition switch to the ON position again.
  • If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the ignition switch to the ON position again.
Inlet Port Memory Function (FRE)
REC MEMORY SET
[Inlet port memory function (REC)]
  • If the ignition switch is turned to the OFF position while the REC switch is set to ON (recirculation), “Perform the memory” or “Do not perform the memory” of REC switch ON (recirculation) condition can be selected.
  • If “Perform the memory” was set, the REC switch will be ON (recirculation) when turning the ignition switch to the ON position again.
  • If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the ignition switch to the ON position again.
Inlet Port Memory Function (REC)
BLOWER SET
(Foot position setting trimmer)
In FOOT mode, the air blowing to DEF can change ON/OFF.
Foot Position Setting Trimmer

NOTE:
When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10 V or less, the setting of WORK SUPPORT may be cancelled.
