Preliminary Inspection
WARNING: This page is about a different car, the 2004 Mazda 6 and 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
Verify customer complaint by operating suspected system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. For fuse and/or relay identification, refer to illustrations. See Fig 1-Fig 2 . Inspect 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. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found, go to SYSTEM OPERATION CHECK .
