Refer to “A/C System Caution”.
Precautions in Diagnosing TroubleS7RS0B7220002
• Do not disconnect couplers from HVAC control module, battery cable from battery, HVAC control module ground 
wire harness from body or main fuse before confirming diagnostic information (diagnostic trouble code) stored in 
HVAC control module memory.
• Diagnostic information (diagnostic trouble code) stored in  HVAC control module can be checked by display of HVAC 
control module. Also, it can be checked by using SU ZUKI scan tool. Before checking diagnostic information 
(diagnostic trouble code), read this manual and operator's manual for SUZUKI scan tool to know how to read 
diagnostic information (diagnostic trouble code).
• When trouble is diagnosed using diagnostic information  (diagnostic trouble code) on display of HVAC control 
module, keep in your mind that each diagnostic inform ation (diagnostic trouble code) has priority, and only 
diagnostic information (diagnostic troub le code) which has the highest priority is indicated. Therefore, after 
troubleshooting the malfunction, make  sure if there exists any other diagnostic information (diagnostic trouble 
code).
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” before inspection.
Precautions on Servicing A/C SystemS7RS0B7220003
Refer to “Precautions on  Servicing A/C System”.
General Description
Auto A/C System DescriptionS7RS0B7221001
The automatic type air conditioning system (auto A/C) is pr ovided with the function to automatically control the inside 
air temperature, fan speed, air flow outl et direction and air intake position by HVAC control module in addition to 
functions of the manual type air conditioning system (manua l A/C). Once the inside air temperature is set using the 
temperature selector, HVAC control module automatically controls  the inside air temperature at the constant level at all 
times based on the inside air temperature, outside ai r temperature, amount of sunlight and engine coolant 
temperature detected respectively by the inside air te mperature sensor, outside air temperature sensor, sunload 
sensor and ECT sensor. At this time, “FULL AUTO A/ C” appears on the display of HVAC control module.
With the air intake selector pushed in the above state, it is possible to select any position of the air intake actuator.
Then, “FULL AUTO A/C” on the display changes to “AUTO A/C”.

3) Light over sunload sensor vertically with an incandescent lamp approximately 100 W apart from 
about 100 mm (3.94 in.).
NOTE
If sunload sensor is not lighted over with an 
incandescent lamp, DTC  B1504 is detected 
as current DTC even though there is not any 
malfunction.
 
4) Turn ignition switch to ON position.
5) Erase DTC according to instructions displayed on  SUZUKI scan tool.
NOTE
To know how to use SUZUKI scan tool, refer 
to operator’s manual for SUZUKI scan tool.
 
6) After completing the clearance, turn ignition switch to OFF position, and then di sconnect SUZUKI scan 
tool from DLC.
Not Using SUZUKI Scan Tool 1) Turn ignition switch to ON position.
2) Set temperature selector to 25  °C (77  °F). 3) Push AUTO switch (1) and 
MODE (air flow) selector 
(2) at the same time to  have history DTC displayed.
4) Push MODE (air flow) selector (2) and OFF switch  (3) at the same time while history DTC is displayed.
5) Check that “CL” (4) appears on display. “CL” means  that DTC has been cleared.
