Answer 1

B1318 Battery voltage high

The code condition is battery voltage high, have the charging system checked, It is very rare to have a overcharging condition, Disconnecting the battery connection and ensuring the connection are good is the first step, you should also check the GEM module connection if this constantly repeats and the charging system is correct , you would need a GEM module
