Pinpoint Test A: Both High Beams Are Inoperative

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. 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 damage the connector.
  1. A1 CHECK THE HIGH BEAM INDICATOR 
    • Ignition OFF.
    • Place the headlamp switch in the HEADLAMPS ON position.
    • Place the multifunction switch in the HIGH BEAM position.
    • Does the high beam indicator illuminate? 
    • Yes:  VERIFY the SJB fuse 23 (15A) is OK. If OK:

      For Fusion or MKZ, GO to  A5.

      For Milan, GO to  A6.

      If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short.

    • No:  GO to  A2.
  2. A2 BYPASS THE MULTIFUNCTION SWITCH 
    • Place the headlamp switch in the OFF position.
    • Disconnect: Multifunction Switch C202.
    • Place the headlamp switch in the HEADLAMPS ON position.
    • Connect a fused jumper wire between the multifunction switch C202-6, circuit CLF17 (WH/OG), harness side and the multifunction switch C202-8, circuit GD116 (BK/VT), harness side.

    • Do the high beams illuminate? 
    • Yes:  REMOVE the jumper wire. INSTALL a new multifunction switch. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.
    • No:  REMOVE the jumper wire. GO to  A3.
  3. A3 CHECK FOR VOLTAGE TO THE MULTIFUNCTION SWITCH 
    • Measure the voltage between the multifunction switch C202-6, circuit CLF17 (WH/OG), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  REPAIR circuit GD116 (BK/VT) for an open. TEST the system for normal operation.
    • No:  GO to  A4.
  4. A4 CHECK THE HIGH BEAM REQUEST INPUT CIRCUIT FOR AN OPEN 
    • Disconnect: SJB C2280b.
    • Measure the resistance between the multifunction switch C202-6, circuit CLF17 (WH/OG), harness side and the SJB C2280b-27, circuit CLF17 (WH/OG), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to  A7.
    • No:  REPAIR circuit CLF17 (WH/OG) for an open. TEST the system for normal operation.
  5. A5 CHECK THE SJB HIGH BEAM OUTPUT CIRCUIT FOR AN OPEN (FUSION OR MKZ) 
    • Place the headlamp switch in the OFF position.
    • Disconnect: SJB C2280e.
    • Connect a fused jumper wire between the SJB C2280e-1, circuit CDC34 (WH/OG), harness side and the SJB C2280e-2, circuit CLF08 (YE/VT), harness side.

    • Ignition ON.
    • Do the high beams illuminate? 
    • Yes:  REMOVE the jumper wire. GO to  A7.
    • No:  REMOVE the jumper wire. REPAIR circuit CLF08 (YE/VT) for an open. TEST the system for normal operation.
  6. A6 CHECK THE SJB HIGH BEAM OUTPUT CIRCUIT FOR AN OPEN (MILAN) 
    • Place the headlamp switch in the OFF position.
    • Disconnect: SJB C2280e.
      NOTE: An assistant may be required to listen for the high beam shutters activating for this step.
    • Connect a fused jumper wire between the SJB C2280e-1, circuit CDC34 (WH/OG), harness side and the SJB C2280e-2, circuit CLF08 (YE/VT), harness side.

    • Ignition ON.
    • Do the high beam shutters in the headlamps operate? 
    • Yes:  REMOVE the jumper wire. GO to  A7.
    • No:  REMOVE the jumper wire. REPAIR circuit CLF08 (YE/VT) for an open. TEST the system for normal operation.
  7. A7 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the SJB connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new SJB. REFER to INSTALLATION . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
