Doors Do Not Lock Or Unlock Using Remote Transmitter (Explorer & Mountaineer)

WARNING: This page is about a different car, the 1997 Mercury Mountaineer, 1997 Ford Ranger, and 1997 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If vehicle is within 1/2 mile from radio or television towers, remote transmitter operating range may be reduced.

Turn ignition off. Check remote transmitter functions while standing 10 feet from vehicle. If remote transmitter functions do not operate, go to next step. If remote transmitter functions operate, system is operating properly at this time.
Check remote transmitter functions while standing next to or inside of vehicle. If remote transmitter still will not operate, go to next step. If remote transmitter functions operate, go to step 4).
Check all other remote transmitter functions while standing next to or inside of vehicle. If all other remote transmitter functions operate, go to next step. If all other remote transmitter functions do not operate, go to step 6).
Check antenna connection at RAP module. Reconnect antenna or repair faulty connection. Test range with remote transmitter. If range has not improved, go to next step. If range has improved, repair is complete. Retest system.
Turn ignition off. Disconnect antenna from RAP module. Measure resistance in antenna. If resistance is less than 10 ohms, antenna is okay. Reconnect antenna and go to next step. If resistance is greater than 10 ohms, replace antenna and repeat step 1).
Turn ignition off. Connect NGS tester following manufacturers instructions. Turn ignition on. Enter RAP and FUNCTION TESTS. Select TRANSMITTER TIC/DATA. When display comes up, different 8 digit letter or number codes should appear to right of TIC 1 and TIC 2 symbols. TIC 1 is stored for transmitter No. 1. TIC 2 is stored for transmitter No. 2. If one transmitter is stored and displayed next to TIC 1, go to next step. If one transmitter is not stored and displayed next to TIC 1, turn ignition off. Reprogram all remote transmitters. See REMOTE TRANSMITTER under PROGRAMMING. After re-programming, retest system for normal operation.
With ignition off, press and release UNLOCK button on transmitter several times. Transmission received contains TIC for transmitter being operated and DATA for which button has been pressed. If an 8 digit letter or number code does not appear under LAST TIC RECEIVED, and UNLOCK does not appear under LAST DATA RECEIVED, go to next step. If an 8 digit letter or number code appears under LAST TIC RECEIVED, and UNLOCK appears under LAST DATA RECEIVED, go to step 10).
Using other remote transmitter, repeat step 7). If an 8 digit letter or number code appears under LAST TIC RECEIVED, and UNLOCK appears under LAST DATA RECEIVED, go to next step. If an 8 digit letter or number code does not appear under LAST TIC RECEIVED, and UNLOCK does not appear under LAST DATA RECEIVED, go to step 11).
Switch batteries from known good transmitter to malfunctioning transmitter. Press and release UNLOCK button on malfunctioning transmitter several times. If an 8 digit letter or number code appears under LAST TIC RECEIVED, and UNLOCK appears under LAST DATA RECEIVED, replace original batteries from malfunctioning transmitter, then retest system. If an 8 digit letter or number code does not appear under LAST TIC RECEIVED, and UNLOCK does not appear under LAST DATA RECEIVED, replace transmitter, then retest system.
If TIC under LAST TIC RECEIVED agrees with TIC 1 or TIC 2, go to next step. If TIC under LAST TIC RECEIVED does not agee with TIC 1 or TIC 2, turn ignition off. Re-program all remote transmitters. See REMOTE TRANSMITTER under PROGRAMMING. Retest system.
If all buttons pressed for each transmitter create expected LAST DATA RECEIVED output, system is operating properly at this time. If all buttons pressed for each transmitter do not create expected LAST DATA RECEIVED output, turn ignition off. Re-program all transmitters. See REMOTE TRANSMITTER under PROGRAMMING. Retest system.
