Dead odometer and extracting mileage
So I am trying to get some clarification on if its possible to recover mileage from my odometer or ECU?
When I did a search I found this and it says the mileage is stored on the odometer itself. https://www.rx7club.com/showthread.p...=dead+odometer But the I found this saying Mazda can extract the mileage from the ECU. https://www.rx7club.com/showthread.p...=dead+odometer So can clarify this and answer the following two questions? Is the mileage stored on the ECU or the odometer itself? If its stored on the ECU can Mazda recover it or is there a tool I can buy to recover it? Thanks |
The mileage is stored in the cluster within a chip labeled 93C56EN on the speedometer circuit board. You have several options for repair.
1) Repair the bad components on the speedometer circuit board (there is a writeup for it on here) 2) Buy a working cluster and swap the 93C56EN chips (have only a skilled circuit board tech do this) 3) Buy a working cluster and have it programmed and tested by an odometer shop I would recommend option #1 first, then #3 before trying #2. |
Cool thanks for the info
