GMC ACADIA EEPROM type identification

[junmab]

Got this cluster of GMC Acadia.
I found a 6 pins chip labeled: 3PKJ.
Please help me identufy what kind of EEPROM is this.
The wiring from the EEPROM to the MCU proves that this is a 93XX chip, but i can
not figure if it is 9366,9376 or 9386.
Do please try to help with this.

It should be a 93c66

Thank you cluster.

I am trying to be very careful with it.
My PCB looks different, with different components from Buick Enclave, and it is differ from the picture you uploaded:
608977 608978

Please calculate for me 58100km. Now t is 151802km. THX.

:hmmmm2: board is different, chip should still be 93c66 and same pinout to read
608992

[junmab]

Can you calculate the file above ?

[clusters]

File does not look right, what year is this? Always supply ALL info when asking for help.

07-13 were 93c66 for sure, newer ones were 93c86 not sure what year they changed them.

Hi,

The GMC ACADIA is on the road from May 2013.
I attached different readings of the chip as: 9366,9376,9386.
i read them as 16bit.
I was looking at the 9366 file, and i noticed that the string: 5DJ195944
is actually the body number of the car. It makes me think that this is the correct reading,
but i could not locate the km location.609172

It is 93c66 for sure, the mileage block just looks weird.

I see 151802 km in three of the 12 locations, it is the others that confuse me, they are only 36171 km.

This should do the trick

Thanks a lot clusters. Worked just fine.
