ELECTRICAL COMPONENTS 
1. When installing any of the vehicle parts, be careful not to 
pinch or damage any of the wiring harnesses. 
2. Sensors, relays, etc., are sensitive to strong impacts. 
Handle them with care so that they are not dropped or 
mishandled. 
3. The electronic parts used for relays, etc., are sensitive to 
heat. If any service which causes a temperature of 80°C 
(176°F) or more is performed, remove the part or parts in 
question before carrying out the service. 
FUSES AND FUSIBLE LINKS 
1. If a blown-out fuse is to be replaced, be sure to use only a 
fuse of the specified capacity. If a fuse of a capacity larger 
than that specified is used, parts may be damaged and the 
circuit may not be protected adequately. 
Caution 
1. If a fuse is blown-out, be sure to eliminate the cause 
of the problem before installing a new fuse. 
2. Check the condition of fuse holders. If rust or dirt is 
found, clean metal parts with a fine-grained sandpa- 
per until proper metal-to-metal contact is made. 
Poor contact of any fuse holder will often lead to 
voltage drop or heating 
in the circuit and could 
result in improper circuit operation. 1  cnlY589
