QuestionHi I have a 1998 2.3D Nissan Serena. I believe the NATS is malfunctioning. It will not allow me to start the car, I have no central locking or indicators or horn. Other than this all other eletrics are fine. Can I bypass the NATS? Also where is the NATS IMMU? I believe it to be a NATS1 system ( Black fob with lock and unlock buttons). Any help would be appreciated.
Paul.
AnswerPaul,
You cannot bypass unless you do a rewire of the car. The module is under the dash, on the firewall. Source one from a breaking yard and replace yours. Before you do this try your key in the door to unlock the car and then see if it starts. If not the body control module is the problem.
KEY FOB SETUP
1. Close all doors
2. Insert key into and remove it from ignition key cylinder more then six times within 10 seconds. (Hazard warning lamps will then flash twice.)
Note: Withdraw key completely from ignition key cylinder each time.
If Procedure is performed too fast, system will not enter registration mode.
3. Insert key into ignition key cylinder and turn to ACC position
4. Push any button on key fob once. (Hazard warning lamps will then flash twice.)
5. Do you want to enter any additional key fob id codes? If No - Go to step 9 , if Yes - Go on to next step (6)
Note: A maximum five ID codes can be entered. If more then five ID codes are entered, the oldest ID code will be erased.
6. Unlock the door, then lock again with lock/unlock switch driver side (in power window main switch).
Note: Operate this procedure even if the door is in an unlock state.
7. Push any button on key fob once. (Hazard warning lamp will then flash twice.)
At this time, The oldest ID code is erased and the new ID code is entered.
8. For additional key fobs do steps 6 thru 7.
9. Open driver side door. (END)
After entering ID code, check operation of remote keyless entry system.
