I think I messed up good on this one. Trying to diag an inop coolant gauge in my instrument cluster, I swapped with another used instrument cluster, which also didnt work. So I reinstalled the original cluster and now I get the odometer error message on the display. The only scan tool I have available that reads the becm is EAS unlock tool by RSW solutions. There is no function listed to sync mileage between becm and instrument cluster, but there is one that shows mileage in becm. This now reads 197k, while the vehicle only has 133k! Guessing this would be an error of the becm. whats the best way of repairing this before I mess things up even more?
