DTC 06, 10, 12, 18, 21

A/C amplifier (sensor ground) system inspection

POSSIBLE CAUSE

•  Connector or terminal malfunction

•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and evaporator temperature sensor connector terminal A

•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and ambient temperature sensor connector terminal A

•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and cabin temperature sensor connector terminal A

•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and air mix actuator connector terminal A (L.H.D.), C (R.H.D.)

•  Open circuit in wiring harness between A/C amplifier connector terminal 2N and airflow mode actuator connector terminal C

DTC 06, 10, 12, 18, 21	A/C amplifier (sensor ground) system inspection
POSSIBLE CAUSE	• Connector or terminal malfunction • Open circuit in wiring harness between A/C amplifier connector terminal 2N and evaporator temperature sensor connector terminal A • Open circuit in wiring harness between A/C amplifier connector terminal 2N and ambient temperature sensor connector terminal A • Open circuit in wiring harness between A/C amplifier connector terminal 2N and cabin temperature sensor connector terminal A • Open circuit in wiring harness between A/C amplifier connector terminal 2N and air mix actuator connector terminal A (L.H.D.), C (R.H.D.) • Open circuit in wiring harness between A/C amplifier connector terminal 2N and airflow mode actuator connector terminal C

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	INSPECT SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • Disconnect the A/C amplifier connector (16-pin) and the evaporator temperature sensor connector. • Is there continuity between A/C amplifier connector (16-pin) terminal 2N and evaporator temperature sensor connector terminal A?	Yes	Inspect the connection at the A/C amplifier connector (16-pin).
1		No	Repair the wiring harness.
