DTC B11F0-12; B11F0-13; Air Intake Actuator (Potentiometer) Circuit Short To Power Supply Or Open: Notes

DTC DETECTION DESCRIPTION

System malfunction location	B11F0:12: Air intake actuator (potentiometer) circuit short to power supply B11F0:13: Air intake actuator (potentiometer) circuit open
Detection condition	Malfunction in wiring harness between air intake actuator and climate control unit
Fail-safe function	Malfunction determined when ignition switched ON The air intake actuator is operated in the fresh air side for 7 s after a malfunction is determined and then the drive signal is stopped. Manual operation using REC switch/FRESH switch is not available. Malfunction already exists when ignition switched ON Air intake actuator drive signal is stopped. Manual operation using REC switch/FRESH switch is not available.
Possible cause	Connector or terminal malfunction Air intake actuator malfunction Open circuit in wiring harness between the following terminals: Climate control unit terminal L-air intake actuator terminal C Climate control unit terminal G-air intake actuator terminal D Climate control unit terminal R-air intake actuator terminal E Short to power supply in wiring harness between the following terminals: Climate control unit terminal L-air intake actuator terminal C Climate control unit terminal G-air intake actuator terminal D Climate control unit terminal R-air intake actuator terminal E Climate control unit malfunction
