Nissan Valve Body and TCM Programming

Programming
2006 Nissan Xterra SE 4.0L (VQ40DE) 5-spd (RE5R05A) — 5N1AN08W66C503954
Od Lamp

I am by no means a Nissan expert, but I ran into a strange situation programming a transmission in a 2006 Xterra. I do quite a few of these and rarely have a problem. This customer purchased the valve body directly from the dealer. It was a blank module. I used the Consult 3 to program. I found that there were 4 choices of calibrations to choose from. Only one had the correct body style and part time 4WD. I felt pretty safe in choosing that file. The valve body programmed fine. After clearing the codes I noticed the OD light was on. Pushing the switch had no effect on the light. There were no codes in the TCM. After doing some checking there was a split in production within the 2006 Model Year. The calibration ending in EA10C was for the early production to 09/05 and ZP41A was from 09/05. It was my lucky day because the truck was produced 09/05. The valve body would not accept the ZP41A file so I would estimate that there is a hardware change that goes along with the software. The dealer sent the early version and we need the late one.

If anyone knows different, I would be interested. I have ways to force flash a Nissan file but I didn't want to fit a square peg into a round hole.

I 100% concur, according to FAST and Nissan parts site, by VIN it should have taken ZP41A, I would have done the same as you. Looking up a 2005 does show a EA10C for production up to 9/01/2005....

I am showing the ZP41A file to be correct for this vehicle by VIN.

I also show the ZP41A to be the correct file. I also noticed in the files we purchase the REPR and or the BLNK files are updating. The dates are changing in the files we are purchasing. Had a customer last week who has an older version on c3+ .. I believe v64.. when they went to choose the file for blank programming it was not listed..but he had the file already. I found that to be odd.. so I…

If you are using the Parts site lookup, or FAST to find the correct calibration number, you can simply edit the CSV to point C3+ to the correct (Or Incorrect) file.

Hi Keith, Thank you for the pointer. My concern is if the valve body is a different part number and is physically different, I will be putting the wrong information into it. If it is in fact the same hardware then I have no problem messing with mother nature. The customer is reviewing this with the parts department today. Once an answer is learned we can go from there. FAST showed the build…

The dealer took responsibility for the mistake. Customer sending to dealer on Monday after replacement. They will program correct part.

Michael, I was addressing the CSV that Steven was referencing as the BLNK or REPR file. In the event you have the correct file, but the CSV has it named different so Consult or NERS is showing the incorrect or "no" file available, the CSV can be edited to point to the correct, but incorrectly named file. To clarify, I wholeheartedly agree the dealer sold you the wrong early production TCM.

Steven, Several of the manufactures are making changes to older calibrations. In the IDS system I have noticed update file names have been changed. This requires going online and downloading a file that has changed numbers but is most likely the same as one in already in the offline database. This keeps customers connecting to the internet and helps big brother to keep track. I found this most…
