| Description |
| • |
Overdrive clutch control solenoid valve is a PWM (Pulse Width Modulation) type. |
| • |
When TCM supplies current to solenoid valve, hydraulic pressure of OD clutche and LR brake are controlled by solenoid valve. |

Description and operation Description The mode control actuator is located at the heater unit. It adjusts position of mode door by operating mode control actuator based on signal of A/C control unit. Pressing mode select switch makes the mode control actuator shift in order of Vent → Bi-Level → Floor → Mix.
Repair procedures Inspection 1. Measure the resistance between the terminals. 2. The measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor) Replacement 1.
