Pinpoint Test J: Brake Shift Interlock Inoperative

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
  1. J1 CHECK FOR FEM DTCs 
  2. J2 CHECK FOR VOLTAGE ON CIRCUIT 7S-TA33 (YE/VT) 
    • Key in OFF position.
    • Disconnect: Brake Shift Interlock C322.
    • Key in ON position.
    • Press and hold the brake pedal.
    • Measure the voltage between brake shift interlock C322 pin 2, circuit 7S-TA33 (YE/VT), harness side and ground.

    • Is the voltage greater than 10 volts? 
      1. Yes  : GO to  J5.
      2. No  : GO to J3.
  3. J3 CHECK CIRCUIT 75-TA33 (YE/VT) FOR SHORT TO GROUND 
    • Disconnect: FEM C201f.
    • Measure the resistance between brake shift interlock C322 pin 2, circuit 7S-TA33 (YE/VT), harness side and ground.

    • Is the resistance greater than 10,000 ohms? 
      1. Yes  : GO to J4.
      2. No  : REPAIR the circuit. TEST the system for normal operation.
  4. J4 CHECK CIRCUIT 7S-TA33 (YE/VT) FOR OPEN 
    • Measure the resistance between brake shift interlock C322 pin 2, circuit 7S-TA33 (YE/VT), harness side and FEM C201f pin 15, circuit 7S-TA33 (YE/VT), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : INSTALL a new FEM. REFER to MODULE COMMUNICATIONS NETWORK .
    2. No  : REPAIR the circuit. TEST the system for normal operation.
  5. J5 CHECK CIRCUIT 31-TA33 (BK) FOR AN OPEN 
    • Measure the resistance between brake shift interlock C322 pin 1, circuit 31-TA33 (BK), harness side and ground.
