Trouble Shooting

Check BCM/CLU fuse (10-amp) and CLSTR fuse (10-amp), located in instrument panel fuse block. Before replacing any components, check for poor terminal contacts at component and associated harness connectors. Check for broken (or partially broken) wire inside of insulation which could cause system failure but pass a continuity/voltage check. Check for proper installation of aftermarket equipment. If problem exists, repair as necessary. If problem does not exist, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM  .
