TROUBLESHOOTING
TROUBLESHOOTING PROCEDURES
1. Check air ducts, control rods, etc. for improper connection.
2. Check that the electrical connectors of the relevant components are connected securely and the
fuse is not blown.
3. Perform the troubleshooting as follows; first understand the items to be inspected and the the procedures
comprehensively using Trouble Symptom/Failed Component Cross-Reference Table and then inspect
the appropriate items sequentially.
4. Be sure to perform each component check after disconnecting the relevant connector.
