ISSUE: Corporate, municipal, or police fleets may have had their Ford Motor Company vehicle modified to flash the brake lamps whenever the "police lights" or other aftermarket lights are turned on. These added "police lights" have the potential to disable the brake shift interlock system. The brake shift interlock feature prevents the vehicle from being shifted from park unless the brake pedal is depressed. Disabling of the brake shift interlock feature may enable the operator to inadvertently apply the accelerator instead of the brake pedal when shifting from Park to Drive or Reverse gears.

ACTION: As appropriate, dealers should advise owners (including corporate, municipal, and police agencies) that any vehicle that has been modified with a connection to the brake circuit, or that electrically interfaces with the brake lamps in that manner, should be disconnected IMMEDIATELY and the emergency lighting system should be modified in a manner that does not interfere with normal service operation or the brake shift interlock. In addition, if the high-mount stop lamp flashes when the "police lights" are on, the modification does not conform with the Federal Motor Vehicle Safety Standards (FMVSS) 108 which requires that the high-mount stop lamp only illuminate when applying the brakes.

Installation of warning lights should only be performed with a completely separate electrical system, without connection to any existing vehicle wiring. Connection of aftermarket electrical equipment into the brake lamp circuit or any other circuit which is connected to the Powertrain Control Module (PCM), anti-lock brake computer, air bag system, or any other vehicle system, will cause vehicle malfunction.

ISSUE: The Brake Shift Interlock may be inoperative on some vehicles, not allowing the operator to move the shift lever from the Park position. Stop Lamp operation may also be affected. This may be caused by a deformed Brake Pedal Position Switch electrical connector.

ACTION: Restore Brake Pedal Position Switch operation by installing an updated electrical connector and pigtail. Refer to the following Service procedure for details.

SERVICE PROCEDURE
1. Verify the condition.
2. Remove LH instrument panel insulator. Refer to Workshop Manual Section 501-05.
3. Inspect the Brake Pedal Position Switch electrical connector (2000/2001 - C2002: 2002 - C27 for deformation. Refer to Wiring Diagrams, Section 90 for additional details.
4. If no deformation is found, refer to Workshop Manual, Sections 307-05 & 417-01, for normal diagnostic information.
5. If deformation is found, continue with the following procedure.
6. Disconnect the battery ground cable.
7. Disconnect the Brake Pedal Position Switch electrical connector.
8. Remove the deformed connector by cutting off 4 inches of wire from the harness.
9. Strip approximately 1/4" from the remaining harness and twist the end of each wire.
10. Obtain the repair kit part number 2W1Z-14A411-AAA.
11. The repair kit pigtail wiring comes in 1 piece with connectors.
12. Strip approximately 1/4" of insulation from the repair pigtail and twist the end of each wire.
13. Since the switch is polarity sensitive, match evenly the wire color (LG light green to LG, LG/RD light green with red strip with LG/RD).
14. Use crimp connectors that are found in the repair kit.
15. Evenly position the crimp connectors over the wire repair.
16. To crimp the connectors, use the proper wire crimp tool.
17. Use a heat gun to heat the repaired area until adhesive flows out of both ends of the heat shrink.
18. Reconnect the Brake Pedal Position Switch.
19. Replace the LH instrument panel insulator.
20. Reconnect battery ground cable.
21. Test and verify the Brake Pedal Position Switch operates properly.
