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.
NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
  1. E1 CHECK THE IGNITION SWITCH 
    • Carry out the Ignition Switch Component Test. Refer to COMPONENT TESTING.
    • Is the ignition switch OK? 
    1. YES  : Go to  E2.
    2. NO  : INSTALL a new ignition switch. REFER to Ignition Switch . TEST the system for normal operation.
  2. E2 CHECK CIRCUIT 1522 (DG) FOR A SHORT TO VOLTAGE 
    • Disconnect: SJB Fuse 20 (10A)
    • Key in ON position.
    • Measure the voltage between SJB fuse 20 (10A), circuit 1522 (DG), input side and ground.
    • Is any voltage present? 
    1. YES  : REPAIR circuit 1522 (DG). CLEAR the DTCs. REPEAT the self-test.
    2. NO  : Go to  E3.
  3. E3 CHECK CIRCUITS 1000 (RD/BK) AND 32 (RD/LB) FOR A SHORT TO VOLTAGE 
    • Disconnect: SJB Fuse 21 (10A)
    • Measure the voltage between:
      • SJB fuse 20 (10A), circuit 1000 (RD/BK), output side and ground.
      • SJB fuse 21 (10A), circuit 32 (RD/LB), output side and ground.
    • Is any voltage present? 
    1. YES  : If voltage is present at SJB fuse 20 (10A), REFER to INFORMATION AND ENTERTAINMENT SYSTEMS article to diagnose the audio system.

      If voltage is present at SJB fuse 21 (10A), REFER to STARTING SYSTEM article to diagnose the starting system.

    2. NO  : Go to  E4.
  4. E4 CHECK FOR CORRECT SJB OPERATION 
    • Key in OFF position.
    • Check SJB C2280a for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect: SJB C2280a
    • Make sure the connector seats correctly, then 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. REPEAT the self-test.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
