SERIAL DATA LINE
- Ensure there is proper connection between scan tool and DLC and no loose or missing DLC terminals.
- If all components are not accessible with a scan tool, check for an open in circuit 800 between DLC terminal "M" and S227. (Схема №10)and (Схема №11).
- If one component is not accessible with a scan tool, check for an open in circuit 800 between component and S227. (Схема №11)
- Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. 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. These circuits may be intermittent or resistive when loaded and should be checked by monitoring the voltage drop with the system under load.
- Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found, go to «SYSTEM TESTS»(ref-144212-S09127277422002090400000).
