        Solution:
        1. Turn off the power and try to restart the vehicle. See if the error code disappears.
        2. Turn off the power and check whether the battery plug is oxidized or dirty. Try looking at the battery plug again.

        If the above two points cannot solve the problem, please contact your nearest store to solve it.
