CATERPILLAR 12H 2007

[junmab]

Hi all,

Can any one tell if the hours of Cateripllar 12H '07 are stored in the instruments cluster ?
608620608621
If yes, is it in MCU or external serial EEPROM ?

[junmab]

Any one, please ?

[armen777]

Any one, please ?
Yes inside, 24С02 or Pic16F913 ,if I am not mistaken.

NO !!!!!!!!!!

[armen777]

NO !!!!!!!!!!
Grader not 2007 release?

Sorry, i confused you guys it is 2004 model.
Caterpillar model 12H '04 engine 140HP.
Armen777, how did you open it without braking the glass ?
It is so tight (and sticky) that i am really afraid to brake the glass.

Opened a long time ago.This picture is not mine. I don't even remember glass or plexiglass,you need to warm up with a hairdryer and be very careful

Gogalv,

Can you tell where are the hours stored in this '04 Caterpillar 12H ?
Is it in the MCU or serial EEPROM ? Is it in the ECU ?
I need to know if it worth the trouble opening this instrument.
I really hope someone has the experience with this instrument cluster.

I wrote to you, see 3 post. First you need to open.If you are not ready to read MCU ,don't open.

Gogalv,

See 4 post.....

Armen777, i have no problem reading PIC16F913 with my PICKIT3, but i don't think any one will use
a PIC MCU in such an expensive machine. The PICs are good for hobbies not for tractors.
Gogalv uploaded a picture from a table but i can not understand from it where the hours are stored.
I just wanted to know , before i'll try to open this cluster. Could it be that the hours are not in the cluster ?

The picture on the first post from this CAT? I can not exactly say. Maybe I'm wrong.see option gogalv.
