| 1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle |
| 2 | Verify the fault is present. Does the system operate normally? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3 |
| 3 | Turn OFF the ignition. Disconnect the washer fluid level switch connector. Turn ON the ignition. Is the check washer fluid message/indicator displayed on the driver information center (DIC)/instrument panel cluster (IPC)? | Go to Step 6 | Go to Step 4 |
| 4 | Turn OFF the ignition. Connect a fused jumper wire from the washer fluid level switch signal circuit terminal in the washer fluid level switch connector to ground. Turn ON the ignition. Is the check washer fluid message displayed on the DIC? | Go to Step 5 | Go to Step 7 |
| 5 | Turn OFF the ignition. Connect a fused jumper wire across the washer fluid level switch harness connector terminals. Turn ON the ignition. Is the check washer fluid message displayed on the DIC? | Go to Step 9 | Go to Step 8 |
| 6 | Test the washer fluid level switch signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 13 | Go to Step 11 |
| 7 | Test the washer fluid level switch signal circuit for an open or high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 13 | Go to Step 11 |
| 8 | Test the washer fluid level switch ground circuit for an open or high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 13 | Go to Step 11 |
| 9 | Inspect for poor connections at the washer fluid level switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 13 | Go to Step 10 |

Check Washer Fluid Message
The Check Washer Fluid message is controlled by the instrument panel cluster using an input from the washer fluid level switch. The washer fluid level signal circuit is supplied ignition voltage through a resistor then monitored within the instrument cluster. The washer fluid level switch is normally open so the instrument cluster detects ignition voltage on the washer fluid level signal circuit whenever the washer fluid level is not low. When the washer fluid reaches the point where the driver should be informed that the washer fluid is low, the washer fluid level switch closes. When the washer fluid level switch is closed the washer fluid level signal circuit voltage is pulled low, and the instrument panel displays the Check Washer Fluid message on the driver information center. In order to prevent the Check Washer Fluid message from being displayed while sloshing is occurring in the washer fluid container, the instrument cluster is programed with a 1 minute delay before changing states of the Check Washer Fluid message during an ignition cycle.
