Vehicle Access Code Programming

There are 4 modes of vehicle access code programming:

• Add Mode
  
  To add a transmitter without erasing existing transmitter codes. Four transmitter codes can be registered at one time. If number of registered codes exceeds 4, previously registered codes are erased in order starting with first registered code.
• Rewrite Mode
  
  Erases all previously registered transmitter codes and reprograms new transmitters or wireless door lock ECU.
• Confirmation Mode
  
  Informs user of number of existing transmitter codes already programmed in system.
• Erase Mode
  
  Erases all existing codes and cancels wireless door lock operation. Use this procedure if transmitter is lost or stolen.

1. To begin reprogramming, ensure key is not inserted in ignition switch. Ensure driver's door is open and unlocked, and all other doors are closed. Insert key in ignition switch, then remove it.
2. Press door lock switch to LOCK, then within one second, press door lock switch to UNLOCK position. Repeat procedure continuously until door locks have been locked and unlocked 5 times. Close driver's door then open it. This procedure must be carried out within 40 seconds.
3. Press door lock switch to LOCK, then within one second, press door lock switch to UNLOCK position. Repeat procedure continuously until door locks have been locked and unlocked 5 times. Insert key in ignition switch. To enter desired mode, turn ignition switch to ON position and back to LOCK (one cycle), within one second, the specified number of times. See MODE SELECTION  table. Remove key from ignition switch. This procedure must be carried out within 40 seconds.
   MODE SELECTION
   
   

   Mode	No. Of Ignition Switch Cycles
   Add Mode	1
   Rewrite Mode	2
   Confirmation Mode	3
   Erase Mode	5

4. If any mode other than confirmation mode is selected, go to next step. If confirmation mode was selected, door locks will cycle to lock position 0-4 times depending on how many transmitter codes are stored in ECU (example: 2 stored codes = 2 door lock cycles). Registration of confirmation code completed. This procedure must be carried out within 20 seconds.
5. If add mode, rewrite mode or erase mode is selected, to confirm proper initiation, door locks will automatically cycle one time for add mode, 2 times for rewrite mode and 5 times for erase mode. Press new transmitter button for at least one second. This procedure must be carried out within 20 seconds.
6. Door locks should cycle once to confirm transmitter signal was received by ECU. This procedure must be carried out within 3 seconds.
7. Close driver's door, then open it. Press transmitter button again for at least one second. This step must be carried out within 20 seconds.
8. If door locks cycle once, new transmitter code has been successfully accepted. If door locks cycle 2 times, new transmitter code was not successfully accepted. To program another transmitter or make a second attempt at programming in a transmitter code, repeat steps  5 through  8 .
