Hello everyone another New to me 98.5 day after I bought it odometer started blinking and no guages except for the tach. P1698… Checked for bus voltage at the dlc and have 2.45 without the truck running, I figured it was a pcm but I put it in my other 98 and it worked but the pcm out of the other truck didn’t work in this one. I checked the voltage of the 2 bus wires on C3 on the pcm and it seems they only show 0.9 volts? Truck charges and shifts fine just no guages. I also checked the C130 connector and my grounds going into the pcm. Any help would be appreciated thanks guys
