Toyota RAV4>> Electric equipment>> Safety locks and relay>> Safety locks
Safety locks serve in order that break off a chain when current exceeds a certain value that is necessary for protection of devices consumers and wires which can be damaged by too high current. Sharp increase in current is usually caused by malfunction in a chain, most often short circuit.

Fig. 15.8. An arrangement of the block of safety locks and the relay in a motor compartment on models since 2001


Blocks of safety locks are located in the dashboard and in a motor compartment (fig. 15.2, 15.3, 15.4, 15.5, 15.6, 15.7, 15.8) . Numbers, current and chains protected by safety locks are provided in tab. 15.4, 15.5, 15.6, 15.7, 15.8 .
The arrangement of safety locks and electric chains protected by safety locks are given from the inside in a cover of the block of safety locks. Each safety lock has an inscription about the size of the protected current.

Fig. 15.9. Visual check of integrity of a safety lock


If the safety lock fused, so the conductor connecting contacts of a safety lock is broken off (see fig. 15.9 ).

       PREVENTION
Always replace a safety lock with other safety lock of the same power.
Never replace a safety lock more than once, without having defined the reason of its burn-out.


To remove a safety lock, use tweezers for its extraction from the socket. Get a safety lock from tweezers. The wire in a safety lock is swept easily up and will be broken off if the safety lock fused.
Establish the new safety lock calculated on the same current. From a reverse side each safety lock has an inscription about the size of the protected current. Besides, color of a safety lock also corresponds to the maximum size of the passed current (see tab. 15.9 ).
If the established safety lock fuses repeatedly, check the electric chain protected by a safety lock.

       PREVENTION
Do not replace a safety lock at all with a wire crossing point as the electric chain of the car can be seriously damaged.

       PREVENTION
Characteristics of fuses and electric chains can change from year to year.
