Circuit Breakers

Print

REPLACEMENT



See Figure 1

Many circuits, particularly high amperage ones, are protected by resetable circuit breakers. Much like the circuit breakers in a household system, these units will trip when too much current attempts to pass through. On Toyota vehicles, the breaker does not automatically reset, but may be reset manually.

To reset the breaker:

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the circuit breaker.
  4.

  3. Once reset, use an ohmmeter to check for continuity at the pins of breaker. If no continuity is present, the breaker did not reset.

  5. Reinstall the circuit breaker and connect the negative battery cable.
