Test E: Illuminated Entry Does Not Operate With Keypad

  1. Disconnect keyless entry control module 13-pin connector C245 and 16-pin connector C235. Measure resistance between ground and keyless entry control module 16-pin connector C235 terminal No. 5. See Figure . Measure resistance between ground and keyless entry control module 13-pin connector C245 terminals No. 1 and 15. See Figure . If resistances are 5 ohms or less, go to next step. If resistances are greater than 5 ohms, repair open in Black or Black/White wire(s).
  2. Disconnect keyless entry control module 13-pin connector C254 and 16-pin connector C235. Measure voltage between ground and keyless entry control module 16-pin connector C235 terminal No. 1. Measure voltage between ground and 13-pin connector C254 terminals No. 14 and 25. See Figure . If voltages are greater than 9 volts, go to next step. If voltages are less than 9 volts, replace fuse No. 29 (15-amp) or fuse No. 37 (20-amp). Repair Red/White or Black/White wire(s).
  3. Disconnect all keyless entry control module connectors. Measure resistance in Red/White wire between keyless entry control module 13-pin connector C254 terminals No. 10 and 23. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Red/White wire.
  4. Reconnect all keyless entry control module connectors. Measure voltage between ground and keyless entry control module 13-pin connector C254 terminals No. 10 and 23. If voltages are greater than 10 volts, go to next step. If voltages are less than 10 volts, repair short in Red/White wire.
  5. With 13-pin connector C245 connected, measure voltage between ground and keyless entry control module 13-pin connector C245 terminals No. 7 and 19. See Figure . If voltages are greater than 10 volts, go to next step. If voltages are less than 10 volts, replace keyless entry control module.
  6. Turn ignition switch to RUN position. Measure voltage between ground and keyless entry control module 16-pin connector C235 terminal No. 6. If voltage is 10 volts or more, go to next step. If voltage is less than 10 volts, repair open or short in Yellow/Black wire.
  7. Ensure all keyless entry control module connectors are connected. Measure voltage between ground and keyless entry control module 13-pin connector C245 terminal No. 19 while rotating instrument panel dimmer switch to ON position. If voltage is 10 volts or more, go to next step. If voltage is less than 10 volts, repair Black/Light Blue wire.
  8. With keyless entry control module 13-pin connector C245 and 16-pin connector C235 connected, measure voltage between ground and keyless entry control module 13-pin connector C245 terminals No. 7 and 19 with dimmer switch in OFF position. If voltage is not present, go to next step. If voltage is present, replace shorted dimmer switch.
  9. Turn ignition switch to OFF position. Press any keypad button. If both keyhole lights do not illuminate, go to next step. If both keyhole lights illuminate, go to step 12).
  10. Disconnect keyless entry control module 13-pin connector C245. Measure resistance between keyless entry control module 13-pin connector C245 terminals No. 7 and 19. Measure resistance between keyless entry control module 13-pin connector C245 terminals No. 1 and 15. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black/Light Blue wire.
  11. Reconnect keyless entry control module 13-pin connector C245. Measure voltage between ground and keyless entry control module 13-pin connector C245 terminals No. 7 and 19 while pressing any keypad button. If voltage is 10 volts or more for 15 seconds after keypad button is pressed, go to next step. If voltage is not as specified, replace damaged lock cylinder.
  12. Disconnect keyless entry control module 13-pin connector C245 and 13-pin connector C254. Connect a jumper wire between 13-pin connector C254 terminal No. 10 and 13-pin connector C245 terminal No. 7. See Figure and Figure . Connect another jumper wire between 13-pin connector C254 terminal No. 23 and 13-pin connector C245 terminal No. 19. If interior lamps come on, go to next step. If interior lights do not come on, repair open or short in Black/Light Blue or Red/White wire(s).
  13. Check connectors for loose or corroded pins. If pins are loose or corroded, repair as necessary. If pins are not loose or corroded, replace keyless entry control module.
