2005 Nissan Altima SEDAN SL 3.5L V6 A/T????? the NAT bottom tells the BCM to allow starting the engine.

AS YOU CAN SEE CLEARLY THE NAT MUST BE HAPPY FIRST WITH A VALID KEY,
COUNT THE 7 FUSE THAT CAN BE BLOWN. 7 OF THEM.
5+2.

If nothing works, you need the dealership with a scan tool computer.

Nothing you can do , except make it worst . All vehicles from 2000 on have a transponder chip inside the key head . You need a factory or some other professional type scan tool to read codes in the theft - deterrent module . You can't guess an fix the problem . You can buy a launch scan tool for about $800.00 that would work. You need to know the code stored .

Give this a try.....Timing is not as critical with this method...no stop watch needed. Just count in your head...one-one thousand, two-one thounsand, etc, or usestop watch. The most critical step is step #3....wait 10 sec, instead of 7.



1. Ignition "ON", count to 3.

2. Depress/Release pedal 5 times...hard and fast.

3. Count to 10 (not 7!) and fully depress pedal

4. Count to 12 (SES should be blinking), release pedal

5. Count to 10, depress pedal

6. Count to 10, release pedal.

7. Turn off ignition, then 81377951893%26mt_id%3D570%26mpre%3Dhttp%253A%252F%252Fwww.ebay.com%252Fitm%252Flike%252F181377951893%26mid%3D446528%26sdc_id%3D%7Bsdc_id%7D&DealName=12v%20Electric%20Push%20To%20Start%20Engine%20Ignition%20Button%20With%20Red%20Led%20Light%20Up&MerchantID=446528&HasLink=yes&category=0&AR=-1&NG=1&GR=1&ND=1&PN=1&RR=-1&ST=&MN=msnFeed&FPT=SDCF&NDS=1&NMS=1&NDP=1&MRS=&PD=0&brnId=2455&lnkId=8070676&Issdt=150102050536&IsFtr=0&IsSmart=0&dlprc=19.99&SKU=181377951893">start engine.

It's located in the IPDM / ER - intelligent power distribution module - engine room ( under hood fuse box )

when the security light is on while you are cranking the engine, that indicated NATS system malfunction, which is a Nissan security system. you may have an issue with the key it self or with the NATS antenna, which is mounted around the ignition where you insert your key. you cant see the antenna ring, because its inside of the steering column covers by the steering wheel.

DTC 1145 is the intake valve timing control position sensor (left bank [driver's side]). This sensor is probably covered in oil sludge. Remove it and clean it off. Reinstall it and see if the code returns. DTC1614 is in the security system Nissan Vehicle Immobilizer System (NVIS-NATS). It is possible that you have a key that is not registered in the security system. You will need a Consult II and the NATS card to correct this problem.
