Preliminary Inspection

Verify customer's complaint by operating Remote Keyless Entry (RKE) system. Visually inspect for obvious signs of electrical and/or mechanical damage. Check for blown fuses. For fuse and/or relay identification, refer to illustrations. See Fig 1 -Fig 3 . Check for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Pay special attention to harness routing where wires are hinged or make sharp bends. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If fault is not found, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM  .
