The Airconditioner Control Module sets DTC B1245 when the feedback signal of driver temperature actuator(Air mix actuator) has been detected below 0.1V for 0.3 seconds.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Monitoring the Voltage | 1. Poor connection in wiring harness 2. Open in signal(Feedback signal) circuit 3. Open in power circuit 4. Short to ground in signal(Feedback signal) circuit 5. Short to ground in power circuit 6. Faulty driver temperature actuator(Air mix potentiometer) 7. Faulty A/C control Module |
