  1. Arm system as outlined in OPERATION. Disarm system using remote entry transmitter by pressing UNLOCK. If system disarmed and theft indicator turned off, go to step 3). If system did not disarm, go to next step.
  2. Press UNLOCK on remote entry transmitter. If door unlocks, replace RAP module and retest. If door does not unlock, see KEYLESS ENTRY SYSTEM - REMOTE article.
  3. Arm system. Disarm system by turning key in driver's door to UNLOCK. Repeat arming and disarming using all other doors. If system disarmed and theft indicator turned off for all locks, go to step 5). If system did not disarm, go to next step.
  4. Unlock each door. If doors unlock, go to step 11). If doors do not unlock, repair lock, linkage or latch and retest.
  5. Arm system. Disarm system by entering code on door keypad to UNLOCK. If system disarmed and theft indicator turned off, go to step 7). If system did not disarm, go to next step.

  7. Arm system. Disarm system by turning ignition switch on. If system disarmed and theft indicator turned off, system is operating properly. If system did not disarm, go to next step.
  8. Turn ignition off. Connect and operate NGS tester according to manufacturer's instructions. Enter RAP, PID/DATA. Select IGN_RAP PID.Turn ignition off. IGN_RAP PID should read OFF. Turn ignition on. IGN_RAP PID should read RUN/ACC. If both PIDs were correct, system is operating properly. If IGN_RAP PID only read OFF, go tostep 10). If IGN_RAP PID only read RUN/ACC, go to next step.
  9. Turn ignition off. Disconnect RAP module connector C336. Check voltage at connector C336 terminal No. 25 (Black/Pink wire). If voltage is 10 volts or more, repair Black/Pink wire and retest. If voltage is less than 10 volts, replace RAP module and retest.
  10. Turn ignition off. Disconnect RAP module connector C336. Turn ignition on. Check voltage at connector C336 terminal No. 25 (Black/Pink wire). If battery voltage exists, replace RAP module and retest. If battery voltage does not exist, repair Black/Pink wire and retest.

  11. Turn ignition off. Connect and operate NGS tester according to manufacturer's instructions. Select DR_DARM PID. DR_DARM PID should read NOT_ACT. Turn key in each lock while monitoring DR_DARM PID. DR_DARM PID should read ACTIVE when key is in unlock position at each lock. If both PIDs were correct, replace RAP module and retest. If DR_DARM PID only read ACTIVE, go to next step. If DR_DARM PID only read NOT_ACT, go to step 13).
  12. Turn ignition off. Disconnect RAP module connector C336. Check resistance between connector C336 terminal No. 9 (Dark Green/Purple wire) and ground. If resistance is more than 10,000 ohms, replace RAP module and retest. If resistance is 10,000 ohms or less, repair Dark Green/Purple wire and retest.
  13. Turn ignition off. Disconnect RAP module connector C336. Check resistance between connector C336 terminal No. 9 (Dark Green/Purple wire) and ground while lock is held in unlock position. If resistance is more than 10,000 ohms, repair Dark Green/Purple wire and retest. If resistance is 10,000 ohms or less, replace RAP module and retest.
