1. Using a scan tool, monitor the SCCM wiper/washer switch PIDs:
   • F_WIP_INT_D1
   • F_WIP_INT_D2
   • F_WIP_INT_D3
   • F_WIP_INT_D4
   • F_WIP_INT_D5
2. Cycle the multifunction switch from off through each of the auto/intermittent sensitivity settings.

Do the PIDs correspond correctly with each setting selection? 

• Yes: GO to 6  .
• No: INSTALL a new wiper/washer switch. REFER to Wiper and Washer Switch .

  If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) .

1. Ignition OFF.
2. Inspect the windshield glass for any cracks, pits or other visible damage around the area of the rain sensor.

Is any windshield damage present near the area of the rain sensor? 

• Yes: INSTALL a new windshield glass. REFER to WINDSHIELD GLASS .
• No: GO to 7  .

1. Ignition ON.
2. Turn the multifunction switch to the low speed wiper setting and while applying water to the windshield surface. Observe the wipe quality, especially around the area or the rain sensor.

Is any streaking present on the windshield around the area of the rain sensor? 

• Yes: GO to 8  .
• No: GO to  10.

1. Ignition OFF.
2. Clean the windshield glass with glass cleaner.
3. Clean the wiper blades with isopropyl alcohol swabs. Wipe the entire length of the wiper blades.
4. Ignition ON.
5. Place the multifunction switch to the low speed wiper setting and while applying water to the windshield surface. Observe the wipe quality, especially around the area or the rain sensor.

Was there noticeable improvement in the wipe quality after cleaning the glass and the wiper blades? 

• Yes: GO to 9  .
• No: INSTALL new wiper blades. GO to 9  .

1. Place the multifunction switch to the auto/ intermittent 5 setting (most sensitive to moisture) while applying water on the windshield above the rain sensor.

Do the wipers operate when water is applied to the windshield surface? 

• Yes: The system is operating correctly at this time. The concern may have been caused by poor wipe quality on the windshield around the rain sensor.
• No: GO to 10  .

1. Ignition OFF.
2. Lightly press the rain sensor against the windshield and release the rain sensor clips.

Does the rain sensor remain adhered to the windshield? 

• Yes: ATTACH the retaining clips. GO to 11  .
• No: The sensor gel-type lens is missing or damaged. INSTALL a new rain sensor. REFER to Rain Sensor .

1. From the outside of the vehicle, inspect the area of the windshield glass where the rain sensor is mounted. The rain sensor contact area should appear black, with no bubbles, air pockets or contaminants between the windshield glass and the rain sensor.

Does the rain sensor contact area appear black, with no bubbles, air pockets or contaminants between the windshield glass and the rain sensor? 

• Yes: ATTACH the retaining clips. GO to 12  .
• No: REMOVE and INSTALL the rain sensor correctly. REFER to Rain Sensor . TEST the system for normal operation. If the concern is still present, GO to  15.

1. Ignition OFF.
2. Disconnect: Rain Sensor.
3. Ignition ON.
4. Measure:

   Rain Sensor			Ground
   C914			Chassis Ground
   Pin	Circuit	Measurement	Pin	Circuit
   1	CBB45 (YE)		-	-

Is the voltage greater than 11 volts? 

• Yes: GO to 13  .
• No: VERIFY BJB fuse 45 (5A) is OK. If OK, REPAIR the circuit.

  If not OK, REFER to the appropriate OEM WIRING DIAGRAMS to identify the possible causes of the circuit short.

1. Ignition OFF.
2. Measure:

   Rain Sensor			Ground
   C914			Chassis Ground
   Pin	Circuit	Measurement	Pin	Circuit
   3	GD233 (BK)		-	-

Is the resistance less than 3 ohms? 

• Yes: GO to 14  .
• No: REPAIR the circuit.

1. Disconnect: SCCM C2414A.
2. Measure:

   Rain Sensor			SCCM
   C914			C2414A
   Pin	Circuit	Measurement	Pin	Circuit
   2	VDN05 (YE/GY)		20	VDN05 (YE/GY)

Is the resistance less than 3 ohms? 

• Yes: GO to 15  .
• No: REPAIR the circuit.

1. Connect: Windshield Wiper Motor.
2. Inspect the rain sensor connector.
3. Repair:
   • corrosion (replace connector or terminals - clean module pins)
   • damaged or bent pins - replace terminals/pins
   • pushed-out pins - replace pins as necessary
4. Reconnect the rain sensor connector. Make sure it seats and latches correctly.
5. Ignition ON.
6. Turn the wiper/washer switch to the auto/intermittent 5 position (most sensitive to moisture) while applying water to the windshield surface. Observe the wiper operation.

Do the wipers operate when water is applied to the windshield surface? 

• Yes: 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.
• No: 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 rain sensor. REFER to Rain Sensor .
