Pinpoint Test AF : U3011:13

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  1. AF1 CHECK FOR OTHER SASM (STEERING ANGLE SENSOR MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the SASM self-test.

    Is DTC U3003:1C present? 

    Yes  GO to Pinpoint Test AD 
    No  GO to  AF2

  2. AF2 CHECK FOR OTHER BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the BCM self-test.

    Are any Diagnostic Trouble Codes (DTCs) present in the BCM? 

    Yes  DIAGNOSE all Diagnostic Trouble Codes (DTCs). Refer to: Body Control Module (BCM) .
    No  GO to  AF3

  3. AF3 CHECK THE SASM (STEERING ANGLE SENSOR MODULE) IGNITION VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

    • Ignition OFF.

    • Disconnect SASM-clockspring C218A .

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 C2280A-5

    Is the resistance less than 3 ohms? 

    Yes  GO to  AF4
    No  VERIFY BCM fuse 20 (7.5A) is OK. If OK, REPAIR the affected circuit for high resistance or an open. If not OK, REFER to the OEM Wiring Diagrams to identify the cause of the circuit short.

  4. AF4 VERIFY ALL WIRING CONNECTIONS

    • Ignition OFF.

    • Disconnect all SASM-clockspring electrical connectors.

    • Disconnect all BCM electrical connectors.

    • Disconnect all in-line connectors between the SASM-clockspring and the BCM.

    • Using a good light source, inspect disconnected electrical connectors for the following:

      • corrosion - install new connector or terminal and clean the module pins
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary
      • spread terminals - install new terminals as necessary

    Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals? 

    Yes  GO to  AF5
    No  REPAIR the connector or terminals. Refer to Connector Repair Procedures for schematic and connector information.

  5. AF5 CHECK FOR CORRECT SASM (STEERING ANGLE SENSOR MODULE) OPERATION

    • Connect all in-line connectors between the SASM-clockspring and the BCM. Make sure they seat and latch correctly.

    • Connect all BCM electrical connectors. Make sure they seat and latch correctly.

    • Connect all SASM-clockspring electrical connectors. Make sure they seat and latch 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 SASM-clockspring assembly. Refer to: Clockspring - Vehicles With: Adaptive Steering .
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
