WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. G1 CHECK THE HIGH BEAM OPERATION 
    • Key in OFF position.
    • Place the headlamp switch in the HEADLAMPS ON position.
    • Place the multifunction switch in the HIGH BEAM position.
    • Do the high beams illuminate? 
    1. YES  : Go to  G2.
    2. NO  : Go to Pinpoint Test B .
  2. G2 CHECK THE INPUT FROM THE MULTIFUNCTION SWITCH 
    • Place the headlamp switch in the OFF position.
    • Disconnect: SJB C2280b
    • Place the multifunction switch in the FLASH-TO-PASS position.

    • Measure the resistance between the SJB C2280b-40, circuit 1395 (RD/PK), harness side and the SJB C2280b-4, circuit 1396 (VT/WH), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  G4.
    2. NO  : Go to  G3.
  3. G3 CHECK CIRCUIT 1395 (RD/PK) FOR AN OPEN 
    • Disconnect: Multifunction Switch C202
      • Fig 2: Measuring Resistance Between Multifunction Switch C202-9 And SJB C2280B-40

    • Measure the resistance between the multifunction switch C202-9, circuit 1395 (RD/PK), harness side and the SJB C2280b-40, circuit 1395 (RD/PK), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES . TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  4. G4 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? 
    1. YES  : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
