bq78pl116 SMBus command issue

Could somebody help me?

I find slua591 document describes some commands for user acess, but i can't issurance a reset fuse command or other commands to bq78pl116.

When I send reset fuse command to the bq78pl116, i got a bq78pl116 ack signal, but the fuse failure condition can't clear.

The below command list are which i want to access bq78pl116.

1.  POWERPUMP ENABLE

2. POWERPUMP DISABLE

3. LOCK

4. UNLOCK         

5. RESET FUSE : 0x200B to 0x80 register ==> Start / Slave addr(Wr) / 0x80(command) / 0x0B / 0x20 / Stop

Thanks!
