Pinpoint Test
- CHECK FOR Steering Column Control Module (SCCM) Diagnostic Trouble Codes (DTCs)
- Ignition ON.
- Using a scan tool, perform Steering Column Control Module (SCCM) self-test.
- Are any Steering Column Control Module (SCCM) Diagnostic Trouble Codes (DTCs) present?
- Yes: REFER to DTC CHART: STEERING COLUMN CONTROL MODULE (SCCM) .
- No: GO to 2 on page 2.
- CHECK THE WIPER/WASHER SWITCH Parameter Identifications (PIDs)
- Using a scan tool, view Steering Column Control Module (SCCM) Parameter Identifications (PIDs).
- Make sure the wiper/washer switch is in the OFF position.
- Verify the status of each of the following Steering Column Control Module (SCCM) Parameter Identifications (PIDs) is displayed as OFF:
- Front Wiper Select Switch A (F_WIP_INT_D1)
- Front Wiper Select Switch B (F_WIP_INT_D2)
- Front Wiper Select Switch C (F_WIP_INT_D3)
- Front Wiper Intermittent Data 4 (F_WIP_INT_D4)
- Front Wiper Intermittent Data 5 (F_WIP_INT_D5)
- Front Wiper Command Low Speed (F_WIP_SLO_SW)
- Front Wiper Command High Speed (F_WIPE_FAST_SW)
- Washer Switch Front (F_WASH_SW)
- Single Wipe Stroke (WIPE_SINGLE)
- Rear Wiper Off Switch (R_WIPE_OFF_SW)
- Rear Wiper Delay 1 (R_WIPE_DEL1)
- Rear Wiper Delay 2 (R_WIPE_DEL2)
- Washer Switch Rear (R_WASH_SW)
- Are all of the Parameter Identifications (PIDs) displayed as OFF?
- Yes: GO to 3 on page 2.
- No:
INSTALL a new wiper/washer switch. REFER to WIPER AND WASHER SWITCH . TEST the system for normal operation.
If the concern is still present, INSTALL a new Steering Column Control Module (SCCM). REFER to STEERING COLUMN CONTROL MODULE (SCCM) .
- CHECK FOR CORRECT WINDSHIELD WIPER MOTOR OPERATION
- Ignition OFF.
- Disconnect and inspect the windshield wiper motor connector.
- Repair:
- corrosion (replace connector or terminals - clean module pins)
- damaged or bent pins - replace terminals/pins
- pushed-out pins - replace pins as necessary
- Reconnect the windshield wiper motor connector. Make sure it seats and latches correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes: CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW the Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (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.
