Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Inspect ambient temperature sensor. (See AMBIENT TEMPERATURE SENSOR INSPECTION.) • Is it okay? | Yes | Go to the next step.
No | Replace ambient temperature sensor. (See AMBIENT TEMPERATURE SENSOR REMOVAL/INSTALLATION.)
2 | • Disconnect front climate control unit connector (16-pin) and ambient temperature sensor connector. • Is there open circuit between following terminals of front climate control unit connector (16-pin) and ambient temperature sensor connector? ― 2I—B ― 2P—A | Yes | Repair wiring harness.
No | Go to the next step.
3 | • Is there short circuit to ground between terminal 2I of front climate control unit connector (16-pin) and terminal B of ambient temperature sensor connector? | Yes | Repair wiring harness.
No | Connect front climate control unit connector, then go to the next step.
4 | • Turn ignition switch to ON position. • Measure voltage at terminal 2I of front climate control unit connector (16-pin). • Is voltage approx. 5 V? | Yes | This system is normal at present. (Erase the past failure from memory.)
No | Inspect the connection of the front climate control unit connector.
