On-Board Diagnostic System DescriptionS7RS0B7221007
NOTE
The diagnostic information as diagnostic
trouble code (DTC) can be known by using
SUZUKI scan tool. For further details, refer to
“DTC Check”.
HVAC control module detect s malfunctions, which may
occur in the following area.
• Outside air temperature sensor
• Inside air temperature sensor
• Evaporator temperature sensor
• Sunload sensor
• ECT sensor
• Temperature control actuator of HVAC unit
• Air flow control actuator of HVAC unit
• A/C refrigerant pressure sensor • HVAC control module
• VSS
• Serial Communication line
• CAN communication line
When HVAC control module detects malfunction, the
“AUTO” indicator lamp (1) flashes to warn and the
diagnostic trouble code (DTC) is stored in the memory of
the module. When diagnosing trouble, the DTC can be
checked according to “DTC Check”.

Step 7. Final confirmation test
Confirm if the problem symptom is troubleshoot and the A/C system is free from any abnormal conditions. If there
existed DTC, clear the DTC. Then , check if the DTC is still detected and if there is any other DTC.
Visual InspectionS7RS0B7224009
Check visually the following parts and systems.

NOTE
When DTC B1503, B1513 and B1514 are indicated together, it is possible that “ORN” wire circuit open.
Inspection item Correction
• Refrigerant ---- leakage and amount
• A/C pipe or hose ---- disconnection, looseness and deterioration
• A/C compressor drive belt ---- looseness and damage Refer to “Compressor Drive Belt Inspection and
Adjustment”.
• Battery ---- fluid level and corrosion of terminal
• Connectors of electric wire harn ess ---- disconnection and friction
• Fuses ---- burning
• Parts ---- installation and damage
• Other parts that can be checked visually

DTC Detecting Condition Trouble Area
Inside air temperature sensor signal voltage is higher than or lower than
specified value for specified time continuously. • Inside air temperature sensor circuit
• Inside air temperature sensor
• HVAC control module
Step
Action YesNo
1 Inside air temperature sensor signal circuit check
1) Disconnect inside air temperature sensor connector.
2) Check for proper connection to inside air temperature
sensor at “PNK/BLK” and “ORN” wire terminals.
3) If OK, measure voltage between “PNK/BLK” wire terminal of inside air temp erature sensor connector and
vehicle body ground with ignition switch turned ON.
Is voltage 4 – 6 V? Go to Step 5.
Go to Step 2.
