How to Solve Foxflash Read Fail on Ford SID211
Problem: It’s a Ford Transit Custom 2017 with SID211 ECU, Foxflsah reads id ok but reading error. Any idea?
Solution:
Charge maintenance at 14V+.
Read and clear all defaults in your ecu and try. If not good repeat this and remove the positive connector on your battery for 5min and try again.
