Diagnostic Aids

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 1996 Ford RV Cutaway, 1996 Ford Pickup, 1996 Ford F-Super Duty, 1996 Ford Econoline, and 1996 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: DTC 0563 may be a temporary condition with a 24-volt jump start. DTC 0562 may be a temporary condition at crank only.

  1. 1) DTC 0560, 0562 Or 0563: Check Battery Voltage
    Turn ignition on. Measure voltage across battery terminals. If voltage is more than 9.5 volts, go to step  12) (Econoline), or go to next step (Pickup). If voltage is 9.5 volts or less, service discharged battery.

  2. 2) Check For Battery Voltage

    Measure voltage between negative battery terminal and output terminal (Yellow wire) of fuse No. 9 at power distribution center. If battery voltage is present, go to next step. If battery voltage is not present, locate and repair open circuit in Yellow wire.

  3. 3) Check Fuse

    Remove and inspect fuse No. 9 at power distribution center. If fuse is okay, go to next step. If fuse is blown, locate and repair short to ground and replace fuse.

  4. 4) Check Circuit No. 37

    Turn ignition off. Remove PCM relay from power distribution center. Measure resistance between non-powered side of No. 9 fuse holder and Yellow wire at PCM relay connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, locate and repair open in Yellow wire.

  5. 5) Check Ignition Feed To Diode

    Remove diode from power distribution center. Turn ignition on. Measure voltage between negative battery terminal and ignition feed side of diode connector. If battery voltage is present, go to next step. If battery voltage is not present, locate and repair open in Red/Light Green wire or replace defective ignition switch.

  6. 6) Check Diode

    Turn ignition off. Using an ohmmeter, check diode continuity. Ensure continuity exists in one direction only. Replace diode as necessary. If diode is okay, go to next step.

  7. 7) Check Black/Yellow Wire

    Measure resistance of Black/Yellow wire between PCM relay connector and non-powered side of diode connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open circuit in Black/Yellow wire.

  8. 8) Check Ground Circuit

    Turn ignition off. Measure resistance between negative battery terminal and circuit No. 57 (Black wire) at PCM relay connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open circuit in Black wire.

  9. 9) Check Circuit No. 361

    Disconnect PCM 104-pin connector, and inspect for damaged pins, corrosion and loose wires. Repair as necessary. Install Breakout Box (014-00950), leaving PCM disconnected. Measure resistance of Red wire between PCM relay connector and test pins No. 71 and 97 at breakout box. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, locate and repair open in Red wire between PCM relay and PCM connector.

  10. 10) Check PWR GND Circuit

    Measure resistance between negative battery terminal and test pins No. 25, 51, 76, 77 and 103 at breakout box. If each reading is less than 5 ohms, go to next step.

  11. 11) Check PCM Relay

    Install PCM relay. Turn ignition on. Measure resistance between non-powered side of fuse No. 9 (Yellow wire) and test pins No. 71 and 97 at breakout box. If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or more, replace PCM relay.

  12. 12) Check Voltage At PCM Relay

    Turn ignition off. Remove PCM relay from power distribution box. Measure voltage between PCM relay cavity (Yellow wire) and negative battery terminal. If battery voltage is present, go to step  5). If battery voltage is not present, repair open in Yellow wire between PCM relay and starter relay.

  13. 13) Check Circuit 16 (Red/Light Green Wire)

    Turn ignition off. Measure resistance between non-power side of diode connector (Red/Light Green wire) and PCM relay cavity. If resistance is less than 5 ohms, go to step  8). If resistance is 5 ohms or more, repair open in Red/Light Green wire between diode and relay.

  14. 14) Check PCM Relay

    Turn ignition off. Ensure breakout box is installed, PCM is disconnected and PCM relay is installed. Turn ignition on. Measure voltage between negative battery terminal and breakout box test pins No. 71 and 97. If battery voltage is present and fault is still present, replace PCM. If battery voltage is not present, replace PCM relay.
