On-Board Diagnostic System DescriptionS6RW0D7221004
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 detects malfunctions, which may
occur in the following area.
• Inside air temperature sensor
• Evaporator temperature sensor
• Sunload sensor
• Temperature control actuator
• Air flow control actuator
• Temperature selector of HVAC control module
• Air flow selector of HVAC control module
• Blower speed selector of HVAC control module
• Back-up power supply circuit of HAVC control module
• Serial communication line between BCM and HVAC
control module• Received data from BCM as follows
– Outside air temperature sensor signal
– ECT sensor signal
– A/C refrigerant pressure sensor signal
– VSS signal
– Engine type signal
– Combination meter spec signal
– CAN communication circuit failure signal
When HVAC control module detects malfunction, the “A/
C” indicator light (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”.

DTC Troubleshooting
DTC B1511: Temperature Control Actuator (Position Sensor) and/or Its Circuit MalfunctionS6RW0D7224013
Wiring DiagramStep Action Yes No
1Was “Air Conditioning System Check” performed?Go to Step 2. Go to “Air Conditioning
System Check”.
2Wire harness check
1) Turn ignition switch to OFF position.
2) Disconnect connectors from sunload sensor and HVAC
control module.
3) Check for proper connection to each signal circuit
terminal and ground circuit terminal of sunload sensor
and HVAC control module connectors.
4) If OK, check that sunload sensor circuit is as follows.
• Wiring harness resistance of each sunload sensor
signal circuit and ground circuit is less than 3 Ω
• Insulation resistance of each sunload sensor signal
circuit and ground circuit between sunload sensor
connector and vehicle body ground is Infinity
• Circuit voltage of each sunload sensor signal circuit
and ground circuit is 0 – 1 V with ignition switch turned
ON
Are they in good condition?Go to Step 3. Sunload sensor power
supply circuit and/or
signal circuit are open,
short or high resistance.
3Sunload sensor power supply voltage check
1) Connect connector to HVAC control module with ignition
switch turned OFF.
2) Turn ignition switch to ON position.
3) Measure voltage between signal terminal and ground
terminal of sunload sensor connector.
Is voltage 4.5 – 5.5 V?Go to Step 4. Substitute a known-
good HVAC control
module and recheck.
4Sunload sensor check
1) Check sunload sensor for performance referring to
“Sunload Sensor Inspection”.
Is it in good condition?Substitute a known-
good HVAC control
module and recheck.Replace sunload
sensor.

The air bag system is designed to activate only in severe
frontal “a” and sideward “b” collisions. It is not designed
to activate in rear impacts, rollovers, or minor frontal and
sideward collisions, since it would offer no protection in
those types of accidents.

The circuit diagram is designed so the current flows from the top of the diagram (power source) to the bottom of the
diagram (ground) as if giving an image of water flow.
[A]: Fuse No.
[B]: Circuit jumping page / direction
NOTE
This means “Jump to the page directed with the arrow(s) by their number.
(For example:” Two arrows directing left” means” Jump to two pages before”.)
You will find the same symbol with the arrows directing opposite in the referenced page. The circuit
continues between the symbols.

[C]: Circuit jumping point / direction
NOTE
The circuit continues to the same symbol with opposite direction within the page.
You will find the other symbol in the direction of the arrow.
