- Cycle the wiper/washer switch from off to the high speed setting and then back to off.
Do the Parameter Identifications (PIDs) correspond correctly with each setting selection?
Yes GO to A8 No INSTALL a new wiper/washer switch. Refer to: Steering Column Multifunction Switch LH . TEST the system for normal operation. If the concern is still present, INSTALL a new SCCM. Refer to: Steering Column Control Module (SCCM) . Refer to: Steering Column Control Module (SCCM) - Vehicles With: Adaptive Steering . - A8 CHECK FOR VOLTAGE TO THE WINDSHIELD WIPER MOTOR
- Ignition OFF.
- Disconnect Windshield Wiper Motor C125 .
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C125-8 Ground
Is the voltage greater than 11 volts?
Yes GO to A10 No VERIFY the BJB fuse 77 (30A) is OK. If OK, GO to A9
If not OK, REFER to the OEM Wiring Diagrams to identify the possible cause of the circuit short. - A9 CHECK THE WIPER RELAY VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect BJB C1035A .
Is the resistance less than 3 ohms?
Yes INSTALL a new BJB relay module. No REPAIR the circuit. - A10 CHECK THE WINDSHIELD WIPER MOTOR GROUND CIRCUIT FOR AN OPEN
Is the voltage greater than 11 volts?
Yes GO to A11 No REPAIR the circuit. - A11 CHECK THE FAIL-SAFE HIGH SPEED WIPER GROUND CIRCUIT CONTROLNOTE: This pinpoint test step uses a test lamp to simulate normal circuit loads. Use only a Rotunda Test Lamp (SGT27000) or 250-300mA incandescent bulb test lamp. To avoid connector terminal damage, use the Rotunda Flex Probe kit for the test lamp probe connection to the vehicle. Do not use the test lamp probe directly on any connector.
- Ignition OFF.
- Disconnect Windshield Wiper Motor C125 .
- Ignition ON.
- Place the wiper/washer switch to the high speed setting and then off.
- Ignition OFF.
Does the test lamp illuminate when the wiper washer switch is in the high speed setting?
Yes GO to A13 No GO to A12 - A12 CHECK THE FAIL-SAFE HIGH SPEED WIPER GROUND CIRCUIT FOR AN OPENNOTE: If steps A2-A11 did not identify the cause of the concern, a double fault may be present. After the fail-safe ground is diagnosed and repaired, it is necessary to check all operation modes and diagnose any symptom still present.
- Disconnect SCCM C226A .
Is the resistance less than 3 ohms?
Yes INSTALL a new wiper/washer switch. Refer to: Steering Column Multifunction Switch LH . TEST the system for normal operation. If the concern is still present, GO to A14 No REPAIR the circuit. - A13 CHECK FOR CORRECT WINDSHIELD WIPER MOTOR OPERATION
- Disconnect and inspect the windshield wiper motor connector.
- Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the windshield wiper motor 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 OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new windshield wiper motor. Refer to: Windshield Wiper Motor . No The system is operating correctly at this time.
