INFOID:0000000010464055

Circuit Breaker

INFOID:0000000010464056

The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

Harness Connector

INFOID:0000000010464057

HARNESS CONNECTOR (TAB-LOCKING TYPE)

• The tab-locking type connectors help prevent accidental looseness or disconnection.
• The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s). Refer to the figure

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

• A new style slide-locking type connector is used on certain systems and components, especially those

related to OBD.

• The slide-locking type connectors help prevent incomplete locking and accidental looseness or disconnec-

tion.

• The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the figure

below.

CAUTION:

• To prevent damage to the parts, never pull the harness or wires when disconnecting the connector.
• To prevent damage to the parts, be careful not to damage the connector support bracket when dis-

HARNESS CONNECTOR (LEVER LOCKING TYPE)

• Lever locking type harness connectors are used on certain control units and control modules such as ECM,

ABS actuator and electric unit (control unit), etc.

• Lever locking type harness connectors are also used on super multiple junction (SMJ) connectors.
• Always confirm the lever is fully locked in place by moving the lever as far as it will go to ensure full connec-

tion.
