: System Title
[B] : Indicates a Relay Block. No shading is used and
only the Relay Block No. is shown to distinguish it
from the J/B
Example: Indicates Relay Block No.1
[C] : ( ) is used to indicate different wiring and
connector, etc. when the vehicle model, engine
type, or specification is different.
[D] : Indicates related system.
[E] : Indicates the wiring harness and wiring harness
connector. The wiring harness with male terminal is
shown with arrows (
).
Outside numerals are pin numbers.
Female Male ( )
The first letter of the code for each wiring harness
and wiring harness connector(s) indicates the
component’s location, e.g, ”E” for the Engine
Compartment, ”I” for the Instrument Panel and
Surrounding area, and ”B” for the Body and
Surrounding area.
When more than one code has the first and second
letters in common, followed by numbers (e.g, IH1,
IH2), this indicates the same type of wiring harness
and wiring harness connector.
[F] : Represents a part (all parts are shown in sky blue).
The code is the same as the code used in parts
position.
[G] : Junction Block (The number in the circle is the J/B
No. and the connector code is shown beside it).
Junction Blocks are shaded to clearly separate
them from other parts.

6 AVENSIS (EWD526E)
B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERM\
INAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor\
.
Stop Light Disconnection Warning
When the ignition SW is turned on and the brake pedal is pressed (Stop ligh\
t SW on), if the stop light circuit is open, the cur
rent
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, \
so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sens\
or to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL \
8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turne\
d off.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major p\
arts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common \
ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
