While measuring the resistance, disconnect the following components one at a time, in order. Stop disconnecting components if the measured resistance rises above 200 ohms.
In-vehicle temperature and humidity sensor C233 Driver side temperature door actuator C2091 Air distribution door actuator C232 Passenger temperature door actuator C2092 Air inlet door actuator C289
Did the resistance rise above 200 ohms?
Yes | INSTALL a new sensor or actuator (the last one to be disconnected). Refer to the appropriate section in Group 412 for the procedure. When installing an actuator, CONNECT the actuator electrical connector before the FCIM. This allows the actuator to be calibrated when the FCIM is connected. | |
