Low Washer Fluid Indicator Malfunction

  1. Verify the washer fluid reservoir is filled up.
  2. Ignition OFF, disconnect the harness connector X1 at the B118 Windshield Washer Fluid Level Sensor.
  3. Test for less than 5 ohms between the ground terminal B and ground.
  4. If greater than the specified value, test the ground circuit for a short to voltage or an open/high resistance.
  5. Ignition OFF, disconnect the harness connector X1 at the P16 Instrument Cluster.
  6. Test for less than 5 ohms between the signal circuit terminal A at the B118B Windshield Washer Fluid Level Switch harness connector and signal terminal 15 at the P16 Instrument Cluster harness connector.
  7. If greater than the specified value, test the signal circuit for a short to voltage or an open/high resistance.
  8. Reconnect all harness connectors.
  9. Ignition ON, command the Driver Information Center Segment test ON and OFF with the scan tool, verify that the low washer fluid indicator display reacts to ON and OFF positions.
  10. If the low washer fluid indicator display stays always ON or always OFF, replace the P16 Instrument Cluster.
  11. If the low washer fluid indicator display changes between ON and OFF, test or replace the B118B Windshield Washer Fluid Level Switch.
  1. Ignition OFF, remove the B118 Windshield Washer Fluid Level Sensor.
  2. Install a wire at terminal A and terminal B. Observe the resistance while moving the level switch.
  3. The resistance should be changing between less than 5 ohms to infinite resistance while moving the level switch.
  4. If not the specified range, replace the B118B Windshield Washer Fluid Level Switch.
