Dtc B1513: Temperature Control Actuator (Motor) And/Or Its Circuit Malfunction - Suzuki SX4 Service Manual

Step
5 Position sensor of temperature control actuator power
supply voltage check
1) Turn ignition switch to OFF position.
2) Disconnect connector from temperature control actuator.
3) Turn ignition switch to ON position.
4) Measure voltage between.
• Position sensor power supply terminal and position
sensor ground terminal of air flow control actuator
connector
• Position sensor signal terminal and position sensor
ground terminal of air flow control actuator connector
Is voltage 4.5 – 5.5 V?

DTC Troubleshooting
Step
1 Was "Air Conditioning System Check" performed?
2 DTC check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch to ON position and check DTC.
Is DTC B1511 detected together?
3 Visual Check
Check if there is any obstruction in operating range of
actuator linkage and if actuator linkage operates smoothly.
Is it in good condition?
