Dtc B1513: Temperature Control Actuator And/Or Its Circuit Malfunction - Suzuki Grand Vitara 2011 Manual

7B-45 Air Conditioning System:
Step
10 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?
11 Position sensor ground circuit check
1) Connect HVAC control module connector with ignition
switch turned OFF.
2) Measure resistance between "BLK/RED" wire terminal of
air flow control actuator connector and vehicle body
ground.
Is resistance below 5
12 Position sensor ground circuit check
1) Measure resistance between "G52-13" terminal of HVAC
control module connector and vehicle body ground.
Is resistance below 5
13 Air flow control actuator check
1) Check air flow control actuator referring to "Air Flow
Control Actuator Inspection".
Is it in good condition?
