Manual Description
POWER SUPPLY, GROUND & CIRCUIT ELEMENTS, wiring Diagram — POWER — 3, bATTERY POWER SUPPLY — IGNITION SW, iGNITION POWER SUPPLY — IGNITION SW.
HOW TO READ HARNESS LAYOUTS 29, wiring Diagram Codes (Cell Codes) 60, fUSE BLOCK - JUNCTION BOX (J/B) 74, fUSE AND FUSIBLE LINK BOX 75.
SMA for models with roof mounted driving lamp, aCCESSORY POWER SUPPLY — IGNITION SW, if fuse is blown, be sure to eliminate cause incident before, do not partially install fuse; always insert it into fuse holder properly.
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 incident, never wrap outside of fusible link with vinyl tape, never let fusible link touch any other wiring harness, vinyl.
The PTC thermistor generates heat in response current flow, temperature (and resistance) of the thermistor element varies with, electrical resistance will rise sharply to control circuit current, reduced current flow will cause the element cool.
Accordingly and normal circuit current flow allowed resume, bACK DOOR SUB HARNESS/REAR WINDOW DEFOGGER HARNESS, the following Harness Layouts use a map style grid help locate, main symbols of connector (in Harness Layout) are indicated below.
SMA for models with roof mounted driving lamp A, use the chart below to find out what each wiring diagram code stands for, refer to the wiring diagram code in the alphabetical index to find the location (page number) each wiring, a/T Fluid Temperature Sensor TCM Power Supply.
Headlamp - With Daytime Light System, heated Oxygen Sensor 1 Heater (Front), heated Oxygen Sensor 2 Heater (Rear), intake Valve Timing Control Solenoid Valve.
Main Power Supply Ground Circuit, eVAP Canister Purge Volume Control Solenoid Valve, turn Signal Hazard Warning Lamps, vehicle Speed Sensor A/T (Revolution Sensor).
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.
NORMAL OPEN, NORMAL CLOSED AND MIXED TYPE RELAYS, relays can mainly be divided into three types: normal open, normal closed mixed type relays, fUSE BLOCK - JUNCTION BOX (J/B), fUSE AND FUSIBLE LINK BOX.
