Are the 2002 and 2003 ECU's the same?
The ECU on my 2002 6 Speed went bad. I am replacing it with an ECU out of a 2003 6 speed. My question is, are they exactly the same?
I noticed there are a couple of different ECU's for 2002's.

From Nissan4u.com
2002-production date October 2001
Engine control module 1 0.72 kg / 1.589 lb
237105Y700
alternate: 237105Y701
For '01, June — '01, October
237105Y701
alternate: 237105Y703
For '01, October — '01, December
2003-production date November 2002
Engine control module 1 0.7 kg / 1.545 lb
237106Y300
alternate: 237106Y301
For '02, April — '03, February
When I ran a part search on AAA Nissan parts for a 2002 model using the 03 p/n 237106Y300 it returned this alternate for a 2002
Old Part Number 237106Y300
New Part Number 2371M6Y303RE
When I performed the same query using 237106Y300 for a 2003 it also returned 2371M6Y303RE
So I assume that ECM is ok for 02 and 03
On queries for a 2003 using the following 02 P/Ns it returned
237105Y700-no result
Old Part Number 237105Y701
New Part Number 2371M5Y703RE
237105Y703-no result
Lastly, queries for BOTH 2002 and 2003 using 2003 part numbers give
237106Y300 and 237106Y301
New Part Number 2371M6Y303RE
There is certainly some compatability between 02 and 03 Maxima 6 speed ECMs, perhaps even in all cases. Hopefully the cross-referencing will assist you.
