04 gm truck cluster

[speedo kingz]

Reprogrammed a customers 2004 silverado, but he drove it over 200 miles after he sent me cluster, said it was an emergency, but we all have heard the stories. Is it stored anywhere in his vehicle other than cluster? He is extremely worried, becuse I cannot answer him. There are 3 different answers in this forum 1 says it is in the bcm, 1 in pcm and the other says no it is not stored anywhere else.

Thanks

The mileage is stored IN THE INSTRUMENT CLUSTER ONLY if it's a tahoe/suburban/yukon/sierra/silverado/H2 and has hours as well (in the cluster). The engine computer stores faults with the mileage but disconnect it for a few minutes and they will be erased.
Now...since you do not specific which exact model you worked on I can tell you that H3 has miles in the BCM and so has Cavalier, new malibu, etc. But in this case the BCM will overwrite the cluster's odo value.

I guess I read your post too fast. You did mention the model; so it's the cluster only.

I have DIGA-Consult and want to adjust mileage for Suburban 2004?
Whats the eeprom number? and can I do it by clib or OBD Plug?

I don't have Suburban in the menue of DIGA-Consult , Can I use Hammer H2?

hi hcip,

you are right again. I found SUBURBAN AND escalades under USA UPDATE 06/03 --> Chevrolet . They both have 95020 chip as shown in Tacho menue, Thank you very much

But I want to ask you, Can I just clip the eeprom without soldring for Suburban and escalades ?

Thanks again, you are a briliant man.

[hcip]

Yes, you can use clip for it
But you need to do some jobs

For Picture no.1 posted you have to desolder some pin to acces the eeprom
and this is not easy job


for Picture 2 & 3, you have to remove needles

so it easy to connect wires at the back of cluster than to do some additional jobs

Used 33/95xxx board (no.40)
plug sw13 cable in Port 4 of adapter

regards

Thank you hcip,
You didn't reply about Cadillac escalades? Does it have the same cluster as GMC SUBURBAN?

Thanks again
