Pinout 2004 Nissan Pathfinder HA 6W000

[driiven]

Hello Everyone, Can't find pinout for this cluster. 2004 Nissan Pathfinder. Has 6 point jtag pins on the back which used my probes to read as a 93c66 but no tool of mine recognizes dump? Anyone familiar with this cluster and what chip it has? Don't want to take it apart as it was hard to find this replacement cluster as it is. Thank you

P.S. All of my tools/manuals seem to skip over 04 year... go from 2000-2003 and 2005+,2007 etc???

Because you read it in 8 bit, read again in 16 bit

Hey Clusters, Thank you for the reply... I am going to remove cluster again now and restart the job. just checked tachosoft 23.1... it shows cluster as having mc9s12? Can I do this from jtag points on back or do I need to remove needles for this job? anyone have points on the back if anything to make job easier?

if its 9S12 then yes you can use the jtag point.
only 4 wires and read.

thank you for the reply vageric... do you have pinout of points for this cluster? Only thing I see on the back I am used to seeing on this one are the two sets of 6 point leads? I have this jtag adapter with pogo pin but It gave me a suspect reading I think. If the needles on this cluster weren't so flimsy and the cluster easier to get another one of this job would be done!

anyone have any other ideas? nothing seems to be working on this one

Yeah, read it the same way you did before as 93c66 only in 16 bit.

The file you posted is read in 8 bit and looks like a proper file only read wrong.

If it has the 6 solder points in a row it is an eeprom, 9S12 are usually two rows of three contacts.

May have helped if you posted pictures of the back of the board.

And by the way, that looks like a 2003 QX4 cluster, your partial part number matches as well.

I am going to try again and see where I end up. Thank you again clusters you are a good man. Wish you a happy healthy new year!

if same as frontier which I belive it should be and depending on circuit board and eeprom or mcu, also tool at hand you might have to connect one wire to resistor
If you run into more problems post pic of board. But with BDM i would say 912/9S12.

Also as clusters says BDM pads

clusters was 100% right, 16 bit and worked perfect! thank you!

Can I replace my 97 cluster with this cluster
