In a practical example shared by technicians, a customer adjusted the dashboard mileage from around 122,659 miles to 61,202 miles using Yanhua YH35XX Programmer and simulator. The new reading appeared correct at first, but after a short drive or restart, the system resynced and restored the old figure. To prevent this, it’s essential to address both components.
One frequently asked question during this process is: Do I need to erase mileage from the FEM (Front Electronic Module) as well? The answer is yes—it’s highly recommended. Resetting the FEM/BDC mileage to zero (using tools like Yanhua Mini ACDP or compatible modules) prevents the system from automatically restoring the original higher reading from the body module.
Yanhua YH35XX excels in these scenarios because it works independently, supports both 35160WT and 35128WT chips
