When I start the car, press brake pedal, and go to put car into gear, the shifter is locked. Sometimes it will let me put it into gear after a while. Do you think this is the saftey switch and how do I replace. There are two electrical components on the breake pedal -- which one would be the safety switch?
Do you
have the same problem?

PINPOINT TEST A (SABLE & TAURUS) Possible Cause Fuse No. 17 (15-amp) or fuse No. 32 (10-amp). Ignition/shifter interlock cable. Brake Pedal Position (BPP) switch connections. Wiring harness. Shift interlock actuator. Diagnostic Procedure 1. Apply the brake pedal and view the brakelights. Do the brakelights illuminate? If so, go to step 7 . If not, go to next step. 2. Measure resistance in fuse No. 17 (15-amp). Is the resistance of the fuse 5 ohms or less? If so, go to step 4 . If not, go to next step. 3. Ensure ignition switch is in OFF position. Disconnect Brake Pedal Position (BPP) switch harness connector. Measure the resistance in Light Green/Red wire between BPP switch harness connector and ground. Is the resistance less than 10 k/ohms? If so, repair short to ground in Light Green/Red wire and test the system for normal operation. If not, go to next step. 4. Measure the resistance in Light Green/Red wire between output side of fuse No. 17 and BPP switch harness connector. Is the resistance less than 5 ohms? If so, go to next step. If not, repair open in Light Green/Red wire and test the system for normal operation. 5. Measure the resistance between BPP switch terminals No. 1 and 2 (component side), while open (OFF) and closed (ON). Is the resistance of the switch greater than 10 k/ohms while OFF, and 5 ohms or less while ON? If so, go to next step. If not, replace BPP switch and test the system for normal operation. See BRAKE PEDAL POSITION SWITCH under REMOVAL & INSTALLATION. 6. Disconnect shift interlock actuator harness connector. Measure the resistance in Red/Light Green wire between shift interlock actuator harness connector and ground. See Fig. 16 . Is the resistance less than 10 k/ohms? If so, repair short to ground in Red/Light Green wire and test the system for normal operation. If not, go to next step. 7. Measure the resistance in Red/Light Green wire between shift interlock actuator harness connector and BPP switch harness connector. Is the resistance less than 5 ohms? If so, go to next step. If not, repair open in Red/Light Green wire and test the system for normal operation. 8. Measure the voltage in Orange wire between shift interlock actuator harness connector and ground. See Fig. 18 . Does battery voltage exist? If so, go to step 12 . If not, go to next step. 9. Turn ignition switch to OFF position. Measure resistance in fuse No. 32 (10-amp). Is the resistance less than 5 ohms? If so, go to step 11 . If not, go to next step. 10. Measure the resistance in Orange wire between shift interlock actuator harness connector terminal No. 3 and ground. See Fig. 19 . Is resistance less than 10 k/ohms? If so, repair short to ground in NOTE: For circuit reference, see CONNECTOR IDENTIFICATION and WIRING DIAGRAMS . For identification of circuits related to this system, but not shown, see POWER DISTRIBUTION article in WIRING DIAGRAMS. Page 1 of 2 SHIFT INTERLOCK SYSTEMS -2001 Ford Taurus SE
