Diagnosis Procedure

AMBIENT SENSOR


Diagnosis Procedure

1.CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND
1. Disconnect ambient sensor connector.
2. Turn ignition switch ON.
3. Check voltage between ambient sensor harness connector and ground.





Is the inspection result normal?
YES - GO TO 2.
NO - GO TO 4.
2.CHECK CIRCUIT CONTINUITY BETWEEN AMBIENT SENSOR AND UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF.
2. Disconnect unified meter and A/C amp. connector.
3. Check continuity between ambient sensor harness connector and unified meter and A/C amp. harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair harness or connector.
3.CHECK AMBIENT SENSOR
