Pinpoint Test D: The Windshield Wipers Operate In High Speed Only
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- D1 CHECK THE SCCM FRONT WIPER COMMAND LOW SPEED (F_WIP_SLO_SW) PID
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: DataLogger - SCCM.
- While monitoring the SCCM F_WIP_SLO_SW PID, place the wiper/washer switch into the windshield wiper LOW speed position.
- Does the PID read ON when the wiper/washer switch is in the LOW speed position?
- Yes : GO to D2.
- No
: INSTALL a new wiper/washer switch. TEST the system for normal operation.
If the concern is still present, GO to D8.
- D2 CHECK THE SCCM DTCs
- Enter the following diagnostic mode on the scan tool: Self Test - SCCM.
- Retrieve and record all SCCM DTCs.
- Are DTCs B1131:08 and B1131:02 both present?
- Yes : GO to D5.
- No
: If only DTC B1131:02 is present, GO to D5.
If only DTC B1131:08 is present, GO to D3.
For all other SCCM DTCs, REFER to the Steering Column Control Module (SCCM) DTC Chart .
- D3 CHECK THE WIPER PARK OPERATION
- Place the windshield wiper switch in the HIGH position.
- When the wiper blades are in the middle of the sweep pattern, place the windshield wiper switch in the OFF position.
- Do the windshield wipers complete the sweep and then park correctly?
- Yes : GO to D5.
- No : GO to D4.
- D4 CHECK THE WINDSHIELD WIPER MOTOR LOGIC GROUND CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: Windshield Wiper Motor C125.
- Measure the resistance between windshield wiper motor C125-3, circuit GD120 (BK/GN), harness side and ground
- Is the resistance less than 5 ohms?
- Yes : INSTALL a new windshield wiper motor. REFER to WIPER MOTOR .
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- D5 CHECK THE LIN CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: SCCM C2414A.
- Ignition ON.
- Measure the voltage between windshield wiper motor C125-4, circuit VDN05 (YE/GY), harness side and ground.
- Is any voltage present?
- Yes : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- No : GO to D6.
- D6 CHECK THE LIN CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Measure the resistance between windshield wiper motor C125-4, circuit VDN05 (YE/GY), harness side and ground.
- Is the resistance greater than 10, 000 ohms?
- Yes : GO to D7.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- D7 CHECK THE LIN CIRCUIT FOR AN OPEN
- Measure the resistance between windshield wiper motor C125-4, circuit VDN05 (YE/GY), harness side and SCCM C2414A-20, circuit VDN05 (YE/GY), harness side.
- Is the resistance less than 5 ohms?
- Yes : GO to D8.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- D8 CHECK FOR CORRECT SCCM OPERATION
- Ignition OFF.
- Disconnect: All SCCM Connectors.
- Check the SCCM connectors for the following conditions:
- corrosion
- pushed-out pins
- spread terminals
- Connect: All SCCM connectors.
- Connect: Windshield Wiper Motor C125.
- Make sure the electrical connectors seat correctly, then operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new SCCM. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
- No : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. TEST the system for normal operation.
