WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: The Flex Probe Kit must be used for all test connections. Use of standard multimeter probes may damage wiring terminals.
  1. F1 CHECK THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE POWER 
    • Key in OFF position.
    • Disconnect: ABS Module C135.
    • Key in ON position.
    • Measure the voltage between ground and:
      • ABS module C135-8, circuit 298 (VT/OG), harness side.
      • ABS module C135-13, circuit 601 (LB/PK), harness side.
      • ABS module C135-14, circuit 483 (RD), harness side.
    • Are the voltages greater than 10 volts? 

    Yes  : GO to F2.

    No  : VERIFY BJB fuse 109 (20A) is OK. If OK, REPAIR circuit 483 (RD) for an open. TEST the system for normal operation.

    VERIFY BJB fuse 106 (40A) is OK. If OK, REPAIR circuit 601 (LB/PK) for an open. TEST the system for normal operation.

    VERIFY CJB fuse 4 (10A) is OK. If OK, REPAIR circuit 298 (VT/OG) for an open. TEST the system for normal operation.

  2. F2 CHECK THE ABS MODULE GROUNDS 
    • Measure the resistance between ground and:
      • ABS module C135-15, circuit 57 (BK), harness side.
      • ABS module C135-12, circuit 57 (BK), harness side.

    • Are the resistances less than 5 ohms? 

    Yes  : REFER to MODULE COMMUNICATIONS NETWORK .

    No  : REPAIR circuit 57 (BK) for an open. CLEAR the DTCs. TEST the system for normal operation.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
