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 shorted or open circuits. Repair as necessary.
  2. Sensor is a photo diode 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.
