  1. Remove glove box. Unplug solar sensor harness connector. Cover sensor with cloth. Connect ohmmeter positive lead to sensor terminal No. 1 (Blue wire), and negative lead to sensor terminal No. 2 (Green/Red wire). Measure and record resistance between sensor terminals.
  2. Remove cloth. Subject sensor to bright light. Again measure resistance between sensor terminals. See SOLAR SENSOR SPECIFICATIONS  table. If resistance is not as specified, replace sensor.
