I've got a 2006 in my shop right now with the following codes:

PO462 -fuel level sensor
41000 - CAN CKT
41001 - CAN CKT
P1212 - TCS CIRC
P1610 - NTAS MALF
P1612 NATS MALF

For FYI, yesterday the oil changed and the serpentine belt replaced, which I am sure had nothing to do with this. The POS now won't start and I can put my finger on it. I am thinking either BCM, PCM, or the immobilizer system went bye bye. Has anyone ever encountered this? All diagnostic information is telling me to check grunds on the BCM, if OK, then replace BCM. If vehicle still doesn't start, then replace ECM.

Thanks

 

check the chip in key, sounds to me like NATS is not reading the key and there fore preventing the car from starting.

Did you try clearing the codes and see what reappears. I've had times were i'd clear the codes and nothing would reappear and everything worked well.

Check ALL fuses before you start replacing anything, I can't stress that enough.

 

I agree clear the codes and see what you get back out. I would also try the ECU reset procedure to see it that works. P= powertrain, 1=Manufacturer Specific, 2=Injector ciruit malfunction or a 6= Computer Output Circuits. Found this:
LOCK MODE
[P1610]
NATS MALFUNCTION
P1610
When the starting operation is carried out five or more
times consecutively under the following conditions, NVIS
(NATS) will shift the mode to one which prevents the
engine from being started.

Unregistered ignition key is used.

BCM or ECM’s malfunctioning.

Check your key. It is free to check at Nissan Dealer.

If it turns out to be the key I recommend you have nissan program it to the car. It looks pretty extensive.

 

The more I read over how it happened, I honestly think it is the key. You don't go in for an oil change with no issues and come out with a non working car. Was there another max there. Maybe the shop tried using the wrong key to start the car multiple times and locked it out.

 

When I clear the codes, the 1610 and 1612 codes reappear.


EDIT: I found the problem to be the BCM. I tested the wires going into it and the car started for a minute. It is definitely not a key issue.

^^^^^Thanks
But the customer is paying for it. Not me. He can pay full price of $399 for a brand spanking new one....

 

damn that's alot.

 

BCM installed and reprogrammed. Car started. Shut off vehicle and re-installed BCM. Now the POS wont start again!! Same symptoms as before. I have both keys the customer owns and vehicle wont start using either of them. According to Nissan, the next step is to replace ECM.

Anyone's help is appreciated on this one.

 

have you tried reprogramming one of the keys? i would try that before ecm replacement. if it started once, it should start again. maybe reset the ecu, clear everything out completely

 

I can have them checked at the dealer I guess. This is really getting on my nerves. To make things worse, there is no diagnostic procedure of the NATS system anywhere other than using Consult II. If the keys check out good, I may also just order one and put it. I may have to program the new one as well.

 

what procedures are you using? Please tell me something other than a chiltons. I have the electronic service manual with the portion discussing troubleshooting for this code. The first thing it mentioned was checking the keys, then the BCM and ECM. So it seems you are doing everying right so far. Don't get frustrated yet, you still aren't done with the steps. I bet it is a PITA though. If you are using the consult II, you should be able to pinpoint the errors right? I want one of those tools, however they are rediculous expensive. I heard 10,000 a piece. Ohh did you scan the codes again to see if there where new or different ones?

 

So I am pretty sure I found the problem.
The TCM sends signal to the Unified Meter and A/C amp. which then sends signal to the PCM. Well, the meter had a penny in it. Yes, you heard it right, a penny. It was laying right on the circuit board and sliding around messing things up. I will post pics later of it. You have to see the size of the entry way for the penny. It looks just like a piggy bank. Amazing!!!

EDIT: Here is the picture of the "Piggy Bank"



What is even funnier about this is that this part has been superceaded by a new one. It has a velcro type cover over the hole. Go Nissan!!!

 

How the heck did a penny even get there? That is freakin amazing concidering nothing even pointed to looking at that. Glad to see you figured this thing out. Ha the PCM, Penny Counting Meter......

 

It fell in between the nav screen and the bezel and wormed its way in there. WTF???

 

I need your help, if possible. I sent my ECM for R&R to a place in Jacksonville, Florida over a month ago, and they initially said it wouldn't work, but they'd provide me a remanufactured one at a total cost of $466.
I did it, as the dealership's price is exorbitant. Now, the NATS is preventing the engine from starting. Any ideas on things that might work?
BTW, I have a 2006 model just like you do. Mine's the GLE model.

Thanks!

 

Hi there! I'm on my 4th Maxima now, and love the product, but am having a problem. My 2006 GLE has been in the shop for a month now with a bad ECM. I sent the old one to a place in Jacksonville, Florida for R&R, but they said the old one couldn't be redone, so they sent a remanufactured one. We asked if they programmed these before sending, and they assured us they do.

When the unit was installed, the NATS system blocked the car from starting. They're still looking into it, but with a remanufactured unit that is the right part, I don't see what the problem could be at this point. Could anyone provide insight as to what to do?

Thanks in advance!
