Troubleshooting Hints - with Temperature Display

1. Check for missing or damaged connector seal at the Outside Air Temperature Sensor.
2. If "SC" or "OC" appears in the temperature display during operation, see the Symptom Table.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of after market electronic equipment which may affect the integrity of other systems (refer to General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis.
