I need help! NATS system malfunction..
Hello,
As some of you know I'm installing an 02 Maxima ECU into my 95 240 with 3.5L VQ. I have a key and ECU out of the same car. I took it to Nissan today to have the key programmed to the ECU because I have a NATS system malfunction - I assumed that the ECU forgot it's memory and needed reprogrammed to the key since it's been out of the Maxima for many months.
When the tech plugged in the Consult II we couldn't get it to recognize the ECU, something is wrong. I double checked that the two communication wires were going to the ECU correctly, that the two power wires had power and the two ground wires were grounded (on the diagnostic plug). I can't figure out why the Consult II wouldn't communicate with my ECU...I can't fix the NATS malfunction until I fix the communication problem..
Also, the tech said that I needed to have the Maxima's key actually inserted into the maxima's ignition switch (which I'm not using, I just have it taped to the NATS module wired by the ECU). I think that's false.
Anybody have any experience here?
Thanks,
Fred
