2013 Nissan Pathfinder BCM replacement
We need correct info on how to proceed with this vehicle. Vehicle brought to us from a body shop (They drove it here) as they replaced roof panel and then rear latch power circuit got blown in BCM. They wanted to try a used BCM which I recommended against. They chose to try this anyway. I was able to copy configuration files for BCM and immobilizer to the used unit. We then called a mobile locksmith who programmed a new intelligent key which enabled the vehicle to crank but not start. Original keys would not program. Codes P1610 & P1611 in ECM (Lock Mode & ID Discord, Immu-ECM) are now in used unit. Security light stays on solid while cranking. To me it looks like P1611 is the issue.
Does anybody know if this is a salvageable attempt (used BCM) to get this vehicle running? In reading info, I believe I read that keys programmed to this year model are locked to the BCM and cannot be used under these conditions. I called a dealership to see if a new BCM comes with keys, they said no, that original keys could be programmed to a new unit. I called my regular mobile programmer but I don't think they could get past the rolling pre-pin because they didn't have access to the dealer system as they are not a locksmith.
With new BCM would the process be to program the keys then copy over configuration files. Would this be all that's needed? The mobile programmer seemed to think that the VIN needed to be entered into the BCM but I never saw that while investigating this process.
Because I am getting too many conflicts on how this system works, could someone please inform me on the correct procedure.
- Can old keys be used with a new BCM or do we need new keys also?
- Is there any way to get the used BCM to marry the ECM, so correct communication handshake takes place?
- If we decide to send the vehicle to the dealer, would you recommend leaving the new BCM installed or put the original back in or possibly leaving the used one that has the crank but no start?
Heck of a deal over a non functioning hatch latch.
Thanks in advance for any help on this mess.
20 digit pins can not be used in another bcm. The code in the ecm is compared to the I’d in the bcm. You can not have more than one bcm programmed to a single ecm however putting the old bcm back in should allow the vehicle to drive again. But you will need a new key fob to use the donor bcm with that ecu. They can only be used with one bcm. That why you’re getting the p1611 and p1610. I don’t…
“cannot have more than one BCM programmed to a single BCM”…? What?
Sorry autocorrect. More than one bcm programmed to one ECM
Yeah you’re going to need a new BCM as it’s basically a one time program. Then make sure everything on the CAN bus is communicating with each other
I appreciate you time already given to this! I'm sorry to be dense but we don't do programming at my small shop so I at least want to know how the system works. Can the original keys be used with a new BCM? This 2013 has a rolling 20 Pre pin that is then translated to a “real pin” to gain access to the immobilizer. Each time the scan tool is backed out of the immobilizer a different pre pin is…
Friend bcm is making pin code. if you are connected to vehicle email me I will give you information you need to finish job free
NO, existing keys are not reusable with a new or used BCM, Nissan keys get marry to the BCM, have to use new keys or if a locksmith have proper equipment and knowledge to re flash existing keys then old keys can be used with any other unit/BCM.
I was wondering if the power liftgate control module that's in the left- quarter panel was related to the original problem ? the newer style Nat's system can be complicated at times. Just a suggestion-Good Luck.
No, this vehicle does not have power lift gate. It's manual and doesn't have module. This makes following the diagrams more difficult as they are all written for having power liftgate. The brown power wire from BCM to latch was dead. Ground signal from rear latch & signals from door switches nor the fob would cause the BCM to power the circuit.
I understand I just assumed that all of them in that era have a power gate module. thanks for clearing that up for Me. Maybe if they had to do some spot welding on it possibly backed up in the BCM and damaged it. I smoked a PCM on a Ford truck several years ago when welding on the vehicle of course Ford had weak ground point's back in that era anyway I guess that goes back to path of least…
