Module communications question, coyote swapped car.

Thats not strange at all its perfectly normal.

forscan does not search for all modules

it does a search first for the ecu and if its found it uses the pcm id to determine what other modules to look for. Forscan was written that way it has absolutely nothing to do with the pcm itself.

The pcm doesnt get the odometer from the cluster.

on the yote the bcm comms the odometer. On the 06 the pcm comms the odometer.

I was hoping Decipha jumped in this thread!

At one point I was hoping to fit a 13 cluster. I got one, wired it up temporarily. And the odometer reading was received from the 13 instrument cluster. So I'm confused as to why you said the BCM/SJB comms the odometer.

In the current config, PCM reports 0 miles. This is the only thing I would like to get working.

Yep your correct, the gen 1 coyote doesnt use the bcm. Its the gen 3 that does where you have to change the speedo in the bcm and then relearn the data in the ecu.

my mistake
