Error Code 05 (Sunload Sensor)

  1. Disconnect negative battery cable. Unplug wiring harness connectors at sunload sensor and EATC control panel. Check wiring and connectors for continuity, shorts and opens. See WIRING DIAGRAMS  . Repair as necessary.
  2. Sensor is a photodiode and can be checked with an ohmmeter. With harness disconnected, there should be some unspecified resistance present across sensor terminals, depending on amount of light available. If resistance is zero ohms, replace sensor.
