DIAGNOSTIC TROUBLE CODE CHART

If malfunction code is displayed during the DTC check, check the circuit listed for that code in the table below. Proceed to the page given for that circuit.

DTC No.	Detection Item	Trouble Area	Memory	Diagnosis Note	See page
11 *1	Room Temperature Sensor Circuit	- Front room temperature sensor - Harness or connector between front room temperature sensor and A/C amplifier - A/C amplifier	○ (8.5 min. or more)	If the room temperature is approx. -20°C(-4°F) or less, DTC 11 may be output even though the system is normal.
12 *2	Ambient Temperature Sensor Circuit	- Ambient temperature sensor - Harness or connector between ambient temperature sensor and A/C amplifier - A/C amplifier	○ (8.5 min. or more)	If the ambient temperature is approx. -50°C(-58°F) or less, DTC 11 may be output even though the system is normal.

14	Engine Coolant Temperature Communication Circuit	- Engine coolant temperature sensor - Harness or connector between engine coolant temperature sensor and ECM - Harness or connector between ECM and A/C amplifier - ECM - A/C amplifier	-	-
17	Rear Evaporator Temperature Sensor Circuit	- Rear evaporator temperature sensor - Harness or connector between Rear evaporator temperature sensor and rear A/C amplifier - A/C amplifier	Rear A/C amplifier communication data	-
18	Emission Gas Sensor Circuit	- Exhaust gas sensor - Harness or connector between exhaust gas sensor and A/C amplifier - A/C amplifier	-	-
19 *1	Rear Room Temperature Sensor Circuit	- Rear room temperature sensor - Harness or connector between rear room temperature sensor and rear A/C amplifier - Rear A/C amplifier	Rear A/C amplifier communication data	If the room temperature is approx. -20°C(-4°F) or less, DTC 11 may be output even though the system is normal.
21 *3	Solar Sensor Circuit	- Solar sensor - Harness or connector between solar sensor and A/C amplifier - A/C amplifier	○ (8.5 min. or more)	If the check is being performed in a dark place, DTC 21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as an inspection light, on the solar sensor. If DTC 21 is still displayed, there could be trouble in the solar sensor circuit.

HINT:

• *1: If the room temperature is approx. -20°C (-4°F) or less, DTC 11 may be output even though the system is normal.

• *2: If the ambient temperature is approx. -50°C (-58°F) or less, a DTC may be output even though the system is normal.

• *3: If the check is being performed in a dark place, DTC 21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC 21 is still displayed, there could be trouble in the solar sensor circuit.

• *4: Compressor lock (DTC 22) is indicated only for a current malfunction.
