Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the B10B Light/Sunload Ambient Sensor.
  2. Ignition OFF, test for less than 60 Ω between the low reference circuit terminal 4 and ground.
  3. If greater than the specified range, test the low reference circuit for an open/high resistance.
  4. Ignition ON, test for B+ between the control circuit terminal 1 and ground.
  5. If less than the specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  6. If all circuits test normal, replace the B10B Light/Sunload Ambient Sensor.
