What is a p1610 code - 2006 Suzuki Reno

Hello. Diagnostic code P1611 means you have low voltage at your relay box; code P1610 means someone kept starting that car 5+ times. Good luck and keep me informed; if you want to.

DTC P1610 Lost Communications with Body Multiple Control (BCM) System
Circuit Description
The PCM uses the serial data circuit to communicate with various other devices and systems in the vehicle. The PCM ensures that communication remains established by monitoring the serial data circuit for state of health messages from the other devices using the circuit. If the PCM detects a loss of the state of health serial data message from the Body Function Controller (BFC), DTC P1610 will be set.

all of my research keeps coming back to p1610 for the P16ff Code but I am not sure.
The code P1610 is a problem with the NATS, or better known as system of vehicle immobilizer. And this arose out of the following:
-are using a q-key is not registered or not transmitting the code
- BCM or ECM are evil, and
now is in "locked mode"
you can do something quick:
1. Confirms the code q yields
2. EXIT THE LOCKED MODE. If the code is p1610 continues with the following with a copy of the vehicle key:
(1) -Place the switch to OFF
(2) -Place the switch in ON with the key registered(do not start the engine). Wait 5 seconds
(3) -Returns the switch to the off position. Wait 5 seconds
(4) -Repeat step 2 and 3 two more times (being a total of 3 times) (
5) -Starts the engine
with this test and write us if t worked. If this is not the case there will be q enter to detail by checking with the diagnostic charts and other things.
The other code does not exist or does not comply with the structure of a code

I had both p1610 and p1612 codes pop up today on me when my car decided to just die. i did a lot of trouble shooting and it led me to removing the negative battery terminal which resets the system and bam, car started right up.

my nissan altima 2002 wont start the battery is brand new and code P-1612 was found out what does the code mean

these are codes for the anti theft system.did you use a key to start it other than one you usually use?if im not mistaken p1610 is a difference of key/unregistered key and 1614 means system entered lockout mode because of key.please let me know how you make out.
