- Instrument Cluster for schematic and connector information.
Normal Operation and Fault Conditions
See Low Washer Fluid Level. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
Possible Sources
- Wiring, terminals or connectors
- Low washer fluid switch
- IPC
Visual Inspection and Pre-checks
- Verify the washer fluid reservoir is full and the ignition has been cycled at least once prior to beginning the pinpoint test for an always on condition or the washer fluid is or has been reported low for a never on condition.
- BN1 CHECK THE MESSAGE CENTER OPERATION
- Ignition ON.
- Close all doors, liftgate and hood.
- Clear all message center warnings by pressing the OK button for each warning present.
- Monitor the door ajar message center warning indicator.
- Open the driver door.
- Clear the message center popup warning.
- Monitor the door ajar message center warning indicator.
Is the door ajar message center warning indicator off with the door closed then does the message center warning indicator turn on with the door open?
Yes If the low washer fluid level message center indicator is inoperative, GO to BN2 If the low washer fluid level message center indicator is always on, GO to BN5 No GO to Pinpoint Test A - BN2 CHECK THE WINDSHIELD WASHER FLUID INDICATOR OPERATION
- Ignition OFF.
- Disconnect Windshield Washer Fluid Level Switch C138.
- Ignition ON.
- Wait one minute.
- Observe the windshield washer fluid level message center indicator.
Is the windshield washer fluid level message center indicator on?
Yes REMOVE the fused jumper wire. INSTALL a new windshield washer fluid level switch or reservoir as necessary. No REMOVE the fused jumper wire. GO to BN3 - BN3 CHECK THE WINDSHIELD WASHER FLUID LEVEL SWITCH GROUND CIRCUIT FOR AN OPEN AT THE WINDSHIELD WASHER FLUID LEVEL SWITCH
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C138-2 Ground
Is the resistance less than 3 ohms?
Yes GO to BN4 No REPAIR the circuit. - BN4 CHECK THE WINDSHIELD WASHER FLUID LEVEL INPUT CIRCUIT FOR AN OPEN
- Disconnect IPC C220.
Is the resistance less than 3 ohms?
Yes GO to BN7 No REPAIR the circuit. - BN5 CHECK THE WINDSHIELD WASHER FLUID INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect Windshield Washer Fluid Level Switch C138.
- Ignition ON.
- Wait one minute.
- Observe the windshield washer fluid level message center indicator.
Did the windshield washer fluid level message center indicator turn on?
Yes INSTALL a new windshield washer fluid level switch. REFER to: Windshield Washer Fluid Level Sensor No GO to BN6 - BN6 CHECK THE WINDSHIELD WASHER FLUID INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect IPC C220.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C220-11 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to BN7 No REPAIR the circuit. - BN7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the IPC connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present
Is the concern still present?
Yes CHECK On-Line Automotive Service Information System (OASIS) for any applicable service articles: TSB, GSB, SSM or FSA If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
