Did you check the fusible links on the positive battery post. There are 4 or 5 built into the post assembly.

if all the fuses are good then you likely shorted out a control unit. Generally a fuse will blow prior to a control unit unless it's like a wheel sensor wire with a/c current shorting out then it fry the whole ABS control unit.

granted the P1610 is lock mode code from the immobiliser.

We see this code when someone tries to start the vehicle 5 times with an unrecognized key. This would only happen if the key lost registration OR one of the control units could not verify the registration. That would e the reason it would crank but not start also.

Would I have to go to Nissan or would be the Ipdm module
Expert:  Jake replied 1 month ago.

The IPDM is not likely to cause these codes.

Since you shorted a wire you would be wise to double check every fuse and fusible link one more time before considering taking it in. Losing power to a control module like the ECM will make it act just like a failed module. The condensor fan running is a fail safe for a control unit failure and your codes indicate a communication error between control units so it's very possible one may be bad, but a bad fuse preventing power to a control unit can cause the impression of a failed control unit when it's just a power issue.
