DTC B10FB-71; Air Intake Actuator Motor Lock: Notes

DTC DETECTION DESCRIPTION

System malfunction location	Air intake actuator motor lock
Detection condition	After the air intake actuator drive signal is output, the air intake actuator does not stop within the target air intake actuator opening angle range for a continuous 9 s or more.
Fail-safe function	Malfunction determined when ignition switched ON Air intake actuator drive signal is stopped right when the malfunction is determined. Malfunction already exists when ignition switched ON Nine seconds after the ignition is switched ON, the air intake actuator drive signal is output normally again. Afterwards, motor output is stopped during malfunction determination.
Possible cause	Connector or terminal malfunction Air intake actuator malfunction Blower unit (air intake link, air intake door) 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 Climate control unit terminal B-air intake actuator terminal A Climate control unit terminal D-air intake actuator terminal B Short to ground 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 B-air intake actuator terminal A Climate control unit terminal D-air intake actuator terminal B 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 terminal B-air intake actuator terminal A Climate control unit terminal D-air intake actuator terminal B Climate control unit malfunction
