2003 Nissan 350Z Code P1212 P1610 P1612 U1001

because you have the U1001 code this may set all the others. What has happened is ecm cannot communicate with other modules. the can network is either shorted or open and a pro must look at this. then if there are remaining codes those have to be looked at after clearing codes and seeing if they come back.

Do i need to replace some parts? Or check the harness and clear the codes?

you have to check harness for a short or an open-Broken then clear codes and see what if any come up

Thanks.. This all started when i shipped my car to a ferry boat..

We checked already all the harness and We diDnt find any shortage or open.. Is it possible the BCM is busted?

I kind of doubt it a pro has to check this as he can use a scanner to help him find the problem there are about 19 modules that are connected to the same line and one of these can be screwing up or wiring going to one can cause the problem. the ecm isn't talking ot he other modules is why the code is set.

We did scan already.. And the problem is CAN COm Circuit.. The ignition switch is off..

so if you know the code start looking I can't fix it for you see pics for diagnostics.

Hi.. The Car is In the dealer shop right now.. And they can't detect the problem.. Its still in LOCK mode(P1610) and IPDM failsafe mode (U1001).. I told them to reprogram the NATS Key..

Hi harrylim888, did you ever get the problem resolved? i am having the same problem, i found some corrosion on the connectors 48 and 49 on my IPDM and was told it can creep up the connector and eat through the wire, i have been hesitant to strip the wire because i dont have those connectors. if this was your problem let me know please.
