Wiring Diagram Codes (Cell Codes) 59, fUSE BLOCK — JUNCTION BOX (J/B) 64, fUSE AND FUSIBLE LINK BOX 65, precautions for Supplemental Restraint System (SRS) AIR BAG” SEAT.
The Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER”, used along, with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain, system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front, air bag, depending on the severity of a collision and whether the front occupants belted unbelted.
Information necessary to service the system safely is included in the SRS and SB section Service Manual, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death, improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system, do not use electrical test equipment on any circuit related to the SRS unless instructed.
When you read wiring diagrams, refer following, "How to Read Wiring Diagrams", "POWER SUPPLY ROUTING" power distribution circuit, when you perform trouble diagnosis, refer following.
"HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES", "How to Perform Efficient Diagnosis an Electrical Incident", check for any Service bulletins before servicing vehicle, the tab-locking type connectors help prevent accidental looseness disconnection.
The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s), refer to the next page for description of slide-locking type connector, do not pull the harness or wires when disconnecting connector, a new style slide-locking type connector is used on certain systems components, especially those.
The slide-locking type connectors help prevent incomplete locking and accidental looseness disconnection, the slide-locking type connectors are disconnected by pushing or pulling the slider, be careful not to damage the connector support bracket when disconnecting connector, hARNESS CONNECTOR (DIRECT-CONNECT SRS COMPONENT TYPE).
SRS direct-connect type harness connectors are used on certain SRS components such as air bag modules seat belt, always pull up to release black locking tab prior removing, always push down to lock black locking tab after installing connector to SRS component, do not pull the harness or wires when removing connectors.
NORMAL OPEN, NORMAL CLOSED AND MIXED TYPE RELAYS, relays can mainly be divided into three types: normal open, normal closed mixed type relays, for detailed ground distribution information, refer PG-16, "Ground Distribution", aCCESSORY POWER SUPPLY — IGNITION SW.
If fuse is blown, be sure to eliminate cause problem, do not partially install fuse; always insert it into fuse holder, remove fuse for ELECTRICAL PARTS (BAT)” vehicle, not used for a long period time.
A melted fusible link can be detected either by visual inspection by, if fusible link should melt, it is possible that critical circuit, (power supply or large current carrying circuit) shorted, in such a case, carefully check and eliminate cause problem.
Never wrap outside of fusible link with vinyl tape, never let fusible link touch any other wiring harness, vinyl, for example, when current is 30A, the circuit is broken within 8 20.
