Remote Transmitter Does Not Operate (Ranger)

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.
  1. Turn ignition off. Disconnect RAP module connectors. Measure voltage between ground and RAP module 22-pin connector terminal No. 12 (White/Light Blue wire). Turn ignition on. Measure voltage between ground and RAP module 26-pin connector terminal No. 25 (Black/Pink wire). If battery voltage is present, go to next step. If battery voltage is not present, check fuse(s). See WIRING DIAGRAMS  . Replace as necessary. If necessary, repair open in White/Light Blue or Black/Pink wire(s).
  2. Check remote transmitter functions while standing 10 yards 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.
  3. Check remote transmitter functions while standing next to or insiill not operate, go to next step. If remote transmitter functions operate, go to step 5).
  4. Check all other remote transmitter functions while standing 10 yards from vehicle. If all other remote transmitter functions do not operate, go to next step. If all other remote transmitter functions operate, go to step 7).
  5. Confirm that while performing step 2) vehicle is more than 1/2 mile away from radio or television towers. If vehicle is closer than 1/2 mile from radio or television towers, a 5 yard range is acceptable. 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, repeat steps 1) and 2).
  6. 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 eplace antenna and repeat steps 1) and 2).
  7. Connect NGS tester following manufacturer's instructions. 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. Re-program all remote transmitters. See REMOTE TRANSMITTER  under PROGRAMMING. After re-programming, repeat steps 1) and 2).
  8. 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 11).
  9. Using other remote transmitter, repeat steps 7) and 8). 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 13).
  10. 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.
  11. If TIC under LAST TIC RECEIVED agrees with TIC 1, go to next step. If TIC under LAST TIC RECEIVED does not agee with TIC 1, turn ignition off. Re-program all remote transmitters. See PROGRAMMING REMOTE TRANSMITTER under DESCRIPTION & OPERATION  . Retest system.
  12. 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.
  13. Using NGS tester, enter RAP and FUNCTION TESTS. Select NOREMOT. If NOREMOT PID displays YES, inspect wiring for shorting pin. If shorting pin is present, remove shorting pin and retest system. If NOREMOT PID does not display YES, replace RAP module, then retest system.
