    • Measure the voltage between multi-function switch C2081-3, circuit 950 (WH/BK), harness side and ground.
    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  A3.
    2. NO  : VERIFY the smart junction box (SJB) fuse 25 (20A) is OK. If OK, go to  A2 .
  2. A2 CHECK CIRCUIT 950 (WH/BK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: SJB C2280b
      • Fig 2: Checking Circuit For Open

    • Measure the resistance between multi-function switch C2081-3, circuit 950 (WH/BK), harness side and SJB C2280b-20, circuit 950 (WH/BK), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  A6.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  3. A3 CHECK MULTI-FUNCTION SWITCH CIRCUIT 57 (BK) FOR AN OPEN 
    • Key in OFF position.
      • Fig 3: Checking Circuit For Open
      GF0023841Courtesy of FORD MOTOR CO.
    • Measure the resistance between multi-function switch C2081-5, circuit 57 (BK), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  A4.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  4. A4 CHECK THE MULTI-FUNCTION SWITCH 
    • Carry out the multi-function switch component test. Refer to COMPONENT TESTING article.
    • Did the multi-function switch pass the component test? 
    1. YES  : Go to  A5.
    2. NO  : INSTALL a new multi-function switch. REFER to STEERING COLUMN SWITCHES article. TEST the system for normal operation.
  5. A5 CHECK THE WINDSHIELD WIPER MOTOR CIRCUIT 57 (BK) FOR AN OPEN 
    • Disconnect: Windshield Wiper Motor C125
      • Fig 4: Checking Circuit For Open
      GF0023842Courtesy of FORD MOTOR CO.
    • Measure the resistance between windshield wiper motor C125-3, circuit 57 (BK), harness side and ground.
    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new windshield wiper motor. REFER to Wiper Motor - Windshield .
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  6. A6 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB connectors.
    • Check for:
      • corrosion.
      • 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 article. 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. CLEAR the DTCs. REPEAT the self-test.
