Trouble Shooting

Check instrument cluster related fuses in instrument panel fuse block before testing. Ensure ground connections are clean and tight. See WIRING DIAGRAMS  . 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  .
