- Clear the DTCs.
Refer to DTC CHECK / CLEAR [12/2013 - 11/2016]
Body Electrical > Navigation System > Clear DTCs
- Recheck for DTCs and check that no DTCs are output.
Body Electrical > Navigation System > Trouble Codes
OK
No DTCs are output.
HINT:
- Connect all the connectors to the front No. 2 speaker assemblies that were disconnected.
- When there is a possibility that either the right or left front No. 2 speaker assembly is defective, inspect by interchanging the right one with the left one.
- Perform the above inspection on both the LH and RH side.
