Check Outside Temperature Indicator

CHECK STEP FOR OUTSIDE TEMPERATURE INDICATOR

Step	Check	Yes	No
1 CHECK AIR CONDITIONER TYPE.	Is the vehicle equipped with auto A/C?	Go to step 6.	Go to step 2.
2 CHECK POWER SUPPLY FOR AMBIENT SENSOR. Turn the ignition switch to OFF. Disconnect the connector from the combination meter. Turn the ignition switch to ON. Measure the voltage between the combination meter terminal and chassis ground. Connector & terminal (i10) No. 11 (+) - Chassis ground (-):	Is the voltage 4 V or more?	Go to step 3.	Except for STI model: Replace the combination meter print circuit. STI model: Replace the meter main assembly.
3 CHECK HARNESS BETWEEN AMBIENT TEMPERATURE SENSOR AND COMBINATION METER. Turn the ignition switch to OFF. Disconnect the connector from ambient sensor. Measure the resistance between the ambient temperature sensor harness connector terminal and combination meter harness connector terminal. Connector & terminal (F78) No. 1 - (i10) No. 11: (F78) No. 2 - (i10) No. 8:	Is the resistance less than 10 Ω?	Go to step 4.	Repair the wiring harness.
4 CHECK AMBIENT SENSOR. Remove the ambient temperature sensor. Check the ambient temperature sensor. <Ref. to INSPECTION , Ambient Sensor.>	Is the ambient temperature sensor OK?	Go to step 5.	Replace the ambient sensor.
5 CHECK OUTSIDE TEMPERATURE INDICATOR. Connect the combination meter harness connector. Connect a resistor (2.2 kΩ) between the terminals of ambient sensor harness connector. Turn the ignition switch to ON and check the outside temperature indicator display.	Is the outside temperature indicator indicating 25°C (77°F)?	Repair the poor contact of ambient temperature sensor harness connector.	Except for STI model: Replace the combination meter print circuit. STI model: Replace the meter main assembly.
6 CHECK POWER SUPPLY FOR COMBINATION METER. Turn the ignition switch to OFF. Disconnect the connector from the auto A/C control module. Turn the ignition switch to ON. Measure the voltage between the auto A/C control module terminal and chassis ground. Connector & terminal (B282) No. 11 (+) - Chassis ground (-):	Is the voltage 4 V or more?	Go to step 7.	Replace the auto A/C control module.
7 CHECK HARNESS BETWEEN AUTO A/C CONTROL MODULE AND COMBINATION METER. Turn the ignition switch to OFF. Disconnect the connector from the combination meter. Measure the resistance between the auto A/C control module harness connector terminal and combination meter harness connector terminal. Connector & terminal (B282) No. 11 - (i10) No. 12:	Is the resistance less than 10 Ω?	Go to step 8.	Repair the wiring harness.
8 CHECK POWER SUPPLY FOR AMBIENT SENSOR. Turn the ignition switch to ON. Measure the voltage between the auto A/C control module terminal and chassis ground. Connector & terminal (B283) No. 9 (+) - Chassis ground (-):	Is the voltage 4 V or more?	Go to step 9.	Replace the auto A/C control module.
9 CHECK HARNESS BETWEEN AMBIENT TEMPERATURE SENSOR AND COMBINATION METER. Turn the ignition switch to OFF. Disconnect the connector from the ambient sensor. Measure the resistance between ambient temperature sensor harness connector terminal, combination meter harness connector terminal and auto A/C control module harness connector terminal. Connector & terminal (F78) No. 1 - (i10) No. 11: (F78) No. 1 - (B283) No. 9: (F78) No. 2 - (i10) No. 8:	Is the resistance less than 10 Ω?	Go to step 10.	Repair the wiring harness.
10 CHECK AMBIENT SENSOR. Remove the ambient temperature sensor. Check the ambient temperature sensor. <Ref. to INSPECTION , Ambient Sensor.>	Is the ambient temperature sensor OK?	Go to step 11.	Replace the ambient sensor.
11 CHECK OUTSIDE TEMPERATURE INDICATOR. Connect the combination meter and auto A/C control module harness connector. Connect a resistor (2.2 kΩ) between the terminals of ambient sensor harness connector. Turn the ignition switch to ON and check the outside temperature indicator display.	Is the outside temperature indicator indicating 25°C (77°F)?	Repair the poor contact of ambient temperature sensor harness connector.	Except for STI model: Replace the combination meter print circuit. STI model: Replace the meter main assembly.
