TROUBLE DIAGNOSIS
CHECKING DISCHARGE AIR
1. Press MODE switch four times and the DEF switch.
2. Each position indicator should change shape (on display).
3. Confirm that discharge air comes out according to the air distri-
bution table. Refer toAT C - 3 0 , "
Discharge Air Flow".
Mode door position is checked in the next step.
If NG, go to trouble diagnosis procedure forAT C - 6 3 , "
Mode Door
Motor Circuit".
If OK, continue the check.
NOTE:
Confirm that the compressor clutch is engaged (sound or visual
inspection) and intake door position is at fresh when the DEF or D/F
is selected.
CHECKING RECIRCULATION
1. Press recirculation ( ) switch one time. Recirculation indica-
tor should illuminate.
2. Press recirculation ( ) switch one more time. Recirculation
indicator should go off.
3. Listen for intake door position change (blower sound should
change slightly).
If NG, go to trouble diagnosis procedure forAT C - 7 7 , "
Intake Door
Motor Circuit".
If OK, continue next check.
NOTE:
Confirm that the compressor clutch is engaged (sound or visual
inspection) and intake door position is at fresh when the DEF or D/F is selected.
CHECKING TEMPERATURE DECREASE
1. Rotate temperature control dial (driver side) counterclockwise
until 18°C(60°F) is displayed.
2. Check for cold air at appropriate discharge air outlets.
If NG, listen for sound of air mix door motor operation. If OK, go to
trouble diagnosis procedure forAT C - 9 3 , "
Insufficient Cooling".Ifair
mix door motor appears to be malfunctioning, go toAT C - 7 1 , "
DIAG-
NOSTIC PROCEDURE FOR AIR MIX DOOR MOTOR (DRIVER)"
orAT C - 7 3 , "DIAGNOSTIC PROCEDURE FOR AIR MIX DOOR
MOTOR (PASSENGER)".
If OK, continue the check.

CHECKING TEMPERATURE INCREASE
1. Rotate temperature control dial clockwise (driver side) until 32°C
(90°F) is displayed.
2. Check for hot air at appropriate discharge air outlets.
If NG, listen for sound of air mix door motor operation. If OK, go to
trouble diagnosis procedure forATC-100, "
Insufficient Heating".If
air mix door motor appears to be malfunctioning, go toAT C - 7 1 ,
"DIAGNOSTIC PROCEDURE FOR AIR MIX DOOR MOTOR
(DRIVER)".
If OK, continue with next check.
CHECK A/C SWITCH
1. Press A/C switch when AUTO switch is ON, or in manual mode.
2. A/C switch indicator will turn ON.
lConfirm that the compressor clutch engages (sound or visual
inspection).
If NG, go to trouble diagnosis procedure forAT C - 8 7 , "
Magnet Clutch
Circuit".
If OK, continue with next check.
CHECKING AUTO MODE
1. Press AUTO switch.
2. Display should indicate AUTO.
lIf ambient temperature is warm, and selected temperature is
cool, confirm that the compressor clutch engages (sound or
visual inspection). (Discharge air and blower speed will
depend on ambient, in-vehicle, and set temperatures.)
If NG, go to trouble diagnosis procedure forAT C - 6 0 , "
Power Supply
and Ground Circuit for Front Air Control", then if necessary, trouble
diagnosis procedure forAT C - 8 7 , "
Magnet Clutch Circuit".
If all operational checks are OK (symptom cannot be duplicated), go
to malfunction simulation tests inAT C - 3 5 , "
How to Perform Trouble
Diagnosis for Quick and Accurate Repair"and perform tests as out-
lined to simulate driving conditions environment. If symptom appears, refer toAT C - 3 5 , "
How to Perform Trou-
ble Diagnosis for Quick and Accurate Repair",AT C - 3 5 , "SYMPTOM TABLE"and perform applicable trouble
diagnosis procedures.

BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
lWith ignition switch ON, CAN communicates with other control units normally.
lControl by BCM is being operated properly.
lWhen ignition switch is OFF, switching to sleep mode is possible.
lEven when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
lThis status shuts down CAN communication when ignition switch is turned OFF.
lIt transmits sleep request signal to IPDM E/R and combination meter.
lTwo seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
lWith ignition switch OFF, CAN communication is not active.
lWith ignition switch OFF, control performed only by BCM is active.
lThree seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
lBCM is activated with low current consumption mode.
lCAN communication is not active.
lWhen CAN communication operation is detected, it switches to CAN communication status.
lWhen a state of the following switches changes, it switches to CAN communication state:
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH) (double cab)
–Rear door switch (driver side, passenger side) No.1 (king cab)
–Rear door switch (driver side, passenger side) No.2 (king cab)
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Door lock assembly LH (key cylinder switch)
lWhen control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
lStatus of combination switch reading function is changed.
