Circuit description
The thermistor ASSY is installed at the front of the condenser. It is used to detect the ambient air temperature, to display the ambient air temperature on the multi display of the combination meter ASSY, and to control “AUTO” of the heater & air conditioner. The resistance of the thermistor ASSY varies along with change of the ambient air temperature. When the ambient air temperature is low, the resistance is high. In contrast, when the ambient air temperature is high, the resistance is small. The combination meter ASSY gives voltage output (5 V) to the thermistor ASSY, and reads variation of voltage along with resistance change of the thermistor ASSY.

The combination meter ASSY receives vehicle speed signals from the brake actuator ASSY via CAN communication. The combination meter ASSY displays the vehicle speed based on the received vehicle speed signals.
NOTE:
Even when the speed meter is normal, slight difference may be present between the reading value and the actual vehicle speed. There are two possible causes for this difference. One is an external cause resulting from the tire size, tire pressure, and tire wear. The other is an internal factor resulting from the allowable range of the reading. Therefore, before troubleshooting, you must first check if these causes are related to the error. The tire size, pressure, and wear (external causes) are checked visually. (Refer to ) The allowable range of reading (internal cause) is checked using a speed meter tester. (Refer to )
) The allowable range of reading (internal cause) is checked using a speed meter tester. (Refer to )Circuit figure

Description of functions
The combination meter ASSY uses the fuel sender gauge ASSY to detect the fuel level in the fuel tank. The fuel sender gauge ASSY has a variable resistor that changes its resistance depending on the fuel level. The fuel sender gauge ASSY receives voltage from the combination meter ASSY and adjusts its voltage based on the resistance that changes according to the fuel level in the fuel tank. The combination meter ASSY detects the voltage between the variable resistor and the resistor inside the combination meter ASSY, and drives the fuel receiver gauge.
