Active Exhaust System Test

- Make sure that the active exhaust control cable is not dislocated or binding.
- Make sure that all component connectors are properly installed and the system fuse is not blown.
- Check the individual components with its connector(s) disconnected.




- Check the components as indicated by the diagnosis chart. If all of the individual components check OK, the problem is probably caused by a faulty Active Exhaust Control Module, and it should be checked/replaced.
