A/C switch Switches the compressor control switch indicator between ON
⇔ OFF with each press while front
blower fan is activated. The circuit used by the BCM to detect an A/C ON request is grounded.
NOTE:
When front blower fan is OFF, the compressor control cannot be activated.
Blower control dial (with
OFF switch) • Blower fan speed is manually controlled with the dial for varying blower speed. When ON, the circuit
used by the BCM to detect a fan ON request signal is grounded.
• Turns air conditioning system OFF.
NOTE:
When blower control dial is turned to any ON position the air conditioning system is activated. (Com-
pressor control state returns to the previous state before air conditioning system was turned OFF.)
DEF switch Switches DEF mode (switch indicator) between ON
⇔ OFF with each press.
• When DEF mode is turned ON, the air conditioning system changes to the following state.
- Air inlet: Fresh air intake
- Air outlet: DEF
- Blower fan: Manual setting.
- Compressor: ON
• When DEF mode is turned OFF, the air conditioning system state returns to the previous state be-
fore DEF mode was selected, but the following state is continued:
- Air inlet: Fresh air intake
- Compressor: ON
NOTE:
When front blower fan is OFF, DEF cannot be activated.

MAX A/C switch Switches the MAX A/C and compressor control switch indicators between ON
⇔ OFF with each press
while front blower fan is activated.
• When MAX A/C mode is turned ON, the air conditioning system changes to the following state.
- Air inlet: Recirculation air intake
- Air outlet: Manual setting
- Blower fan: Manual setting.
- Compressor: ON
• When MAX A/C mode is turned OFF, the air conditioning system state returns to the previous state
before MAX A/C mode is selected. But, the following state is changed:
- Air inlet: Fresh air intake
- Compressor: ON
NOTE:
When front blower fan is OFF, the compressor control cannot be activated.
MODE switches Selects air outlet from VENT, B/L, FOOT, and D/F.
NOTE:
When the air conditioning system is OFF, the air outlet can still be selected.
REC switch • Air inlet is selected to fresh air intake (REC) by pressing this switch.
- REC indicator: ON
NOTE:
• When the air conditioning system is OFF, the air inlet can still be selected.
• When D/F mode or DEF is selected, the REC button is disabled.
Temperature control dial • Selects desired temperature between full cold and full hot.
- Clockwise rotation: Temperature increases.
- Counterclockwise rotation: Temperature decreases.

DIAGNOSIS SYSTEM (BCM)
DIAGNOSIS SYSTEM (BCM)
CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009958322
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
CAN Diag Support Mntr The result of transmit/receive diagnosis of CAN communication is displayed.
