Help with 2007 Chevy Colorado cluster and BCM

[Jdaniels]

Attached are the dumps from an 07 Colorado showing 339,000 KLMs

Cluster chip is 93c56, BCM chip is 25040

I am looking for 170,000 klms

Tachosoft tells me the following but no matter what I try the cluster ends up reading 999,999. is there a checksum in the bcm I am missing?
Any help would be great! Thanks in advance!!!
Car type: Chevrolet Colorado - (Dash+BCM) - 2007-2008 years
Dash chip type is 93c56, in BSI you must find 25040
First reset mileage in dash as shown here:
00D0: xx xx xx xx xx xx xx xx 00 00 00 00 xx xx xx xx
00F0: 00 00 00 00 xx xx xx xx xx xx xx xx xx xx xx xx
than calculate the mileage for BSI:
0080: 17 D7 84 00 17 D7 84 00 17 D7 84 00 xx xx xx xx
where the next bytes:
17 D7 84 00 - is a mileage

gracias por su esfuerzo bernalmotorsport. Logr? entenderlo.

I figured it out. Tachosoft will give you a decent code for the BCM but not the cluster. ( plus you will have to convert your klm value to miles first if your tachosoft
only gives you a miles calculation for the Colorado) If you use the tachosoft code for the "chevy malibu bsi" and reverse the bytes it will work in the cluster
Tachosoft gave me 0400 00A6 for 170000 klms. I entered 0004 A600 into the cluster at the proper location and it all worked. Hope this helps others too!!

you don't even need to do cluster calculation just put FF's on cluster and do the BCM once you open the ignition key the bcm will write new KM on cluster it always goes for the higer value.

Thats even better, thanx!
