Pinpoint Test

1. Ignition ON.
2. Using a scan tool, perform SCCM self-test.

Are any SCCM DTCs present? 

• Yes: For B1131:02 or B1131:08, GO to  4.

  For all other SCCM DTCs  , REFER to DTC CHART: STEERING COLUMN CONTROL MODULE (SCCM) for diagnosis.

• No: GO to 2  .

1. Ignition ON.
2. Using a scan tool, view SCCM PID.
3. While monitoring the SCCM PID F_WIP_SLO_SW, place the wiper/washer switch into the windshield wiper LOW position.

Does the PID read ON when the wiper/washer switch is in the LOW position? 

• Yes: GO to 3  .
• 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. Disconnect: Windshield Wiper Motor.
3. Measure:

   Windshield Wiper Motor			Ground
   C125			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   6	GD120 (BK/GN)		-	-

Is the resistance less than 3 ohms? 

• Yes: GO to 4  .
• No: REPAIR the circuit.

1. Ignition OFF.
2. Disconnect: Windshield Wiper Motor (if not previously disconnected).
3. Ignition ON.
4. Measure:

   Windshield Wiper Motor			Ground
   C125			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   8	CRW03 (VT/WH)		-	-

Is the voltage greater than 11 volts? 

• Yes: GO to  9.
• No: GO to 5  .

1. Ignition OFF.
2. Disconnect: Front Wiper Relay.
3. Measure:

   Front Wiper Relay			Ground
   Front Wiper Relay Socket			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   3	SBB04 (GN/RD)		-	-

Is the voltage greater than 11 volts? 

• Yes: GO to 6  .
• No: VERIFY BJB fuse 4 (30A) 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. Measure:

   Front Wiper Relay			Ground
   Front Wiper Relay Socket			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   2	CDC64 (WH/BU)		-	-

Is the voltage greater than 11 volts? 

• Yes: GO to 7  .
• No: REPAIR the circuit.

1. Ignition OFF.
2. Measure:

   Front Wiper Relay			Ground
   Front Wiper Relay Socket			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   1	GD120 (BK/GN)		-	-

Is the resistance less than 3 ohms? 

• Yes: GO to 8  .
• No: REPAIR the circuit.

1. Carry out the Relay-Micro ISO component test.

   Refer to RELAY - MICRO ISO for schematic and connector information.

Did the wiper relay pass the component test? 

• Yes: REPAIR circuit CRW03 (VT/WH) for an open.
• No: INSTALL a new front wiper relay.

1. Ignition OFF.
2. Inspect the windshield wiper motor 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 windshield wiper motor connector. Make sure it seats and latches correctly.
5. Connect: Front Wiper Relay (if previously disconnected).
6. Operate the system and verify the concern is still present.

Is the concern still present? 

• Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs  address this concern, INSTALL a new windshield wiper motor. REFER to Wiper Motor - Windshield .
• 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.
