Pinpoint Test

1. Close all doors, hood and liftgate.
2. Ignition ON.
3. NOTE: If multiple warnings are present, the message center cycles through each of the warning indicators. Allow the message center to cycle through each display while determining whether the door ajar message center warning indicator is active.

   Open the driver door while monitoring the door ajar message center warning indicator.

Does the driver door ajar message center warning indicator turn off with the driver door closed and illuminate with the driver door open? 

1. Yes: If the WASHER FLUID LEVEL LOW message is never on, GO to 2  .

   If the WASHER FLUID LEVEL LOW message is always on, GO to  5  .

2. No: INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) .

1. Ignition OFF.
2. Disconnect: Washer Fluid Level Switch.
3. Connect a fused jumper wire:

   Washer Fluid Level Switch			Ground
   C138			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   1	CMC20 (VT)		-	Ground

4. Ignition ON.
5. Wait one minute.
6. Observe the low washer fluid message center indicator.

Is the low washer fluid message center indicator on? 

1. Yes: REMOVE the jumper wire. GO to 3  .
2. No: REMOVE the jumper wire. GO to  4  .

1. Measure:

   Washer Fluid Level Switch			Washer Fluid Level Switch
   C138			C138
   Pin	Circuit	Measurement / Action	Pin	Circuit
   1	CMC20 (VT)		2	GD123 (BK/GY)

Is the voltage approximately 5 volts or greater? 

1. Yes: INSTALL a new washer fluid level switch or reservoir as necessary.
2. No: REPAIR the circuit.

1. Ignition OFF.
2. Disconnect: IPC.
3. Measure:

   IPC			Washer Fluid Level Switch
   C220			C138
   Pin	Circuit	Measurement / Action	Pin	Circuit
   8	CMC20 (VT)		1	CMC20 (VT)

Is the resistance less than 3 ohms? 

1. Yes: GO to  7  .
2. No: REPAIR the circuit.

1. Ignition OFF.
2. Disconnect: Washer Fluid Level Switch.
3. Ignition ON.
4. Wait one minute.
5. Observe the low washer fluid message center indicator.

Did the low washer fluid message center indicator turn off? 

1. Yes: INSTALL a new washer fluid level switch or reservoir as necessary.
2. No: GO to 6  .

1. Ignition OFF.
2. Disconnect: IPC.
3. Measure:

   IPC			Ground
   C220			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   8	CMC20 (VT)		-	Ground

Is the resistance greater than 10, 000 ohms? 

1. Yes: GO to 7  .
2. No: REPAIR the circuit.

1. Disconnect and inspect the IPC connector.
2. 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
3. Reconnect the IPC connector. Make sure it seats and latches correctly.
4. Operate the system and determine if the concern is still present

Is the concern still present? 

1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) .
2. 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.
