Dtc B1513: Temperature Control Actuator And/Or Its Circuit Malfunction - Suzuki Swift Sport 2004 Service & Repair Manual

Step
8 Position sensor signal circuit check
1) Measure resistance between "WHT/BLU" wire terminal
of air flow control actuator connector and vehicle body
ground.
Is resistance infinity?
9 Position sensor signal circuit check
1) Measure voltage between "WHT/BLU" wire terminal of
air flow control actuator connector and vehicle body
ground with ignition switch turned ON.
Is voltage 0 V?
10 Position sensor ground circuit check
1) Connect HVAC control module connector with ignition
switch turned OFF.
2) Measure resistance between "ORN" wire terminal of air
flow control actuator connector and vehicle body ground.
Is resistance below 5
11 Position sensor ground circuit check
1) Measure resistance between "G52-3" terminal of HVAC
control module connector and vehicle body ground.
Is resistance below 5
12 Air flow control actuator check
1) Check air flow control actuator referring to "Air Flow
Control Actuator Inspection".
Is it in good condition?
