RAV4 2WD L4-2.0L (1AZ-FE) (2003)
Diagram Legend
O: SYSTEM OUTLINE
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 TERMINAL B 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 light SW on), if the stop light circuit is open, the current 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 sensor 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 turned off.
0: Explains the system outline.
P: Indicates values or explains the function for reference during troubleshooting.
R: Indicates the reference showing the position on the vehicle of Relay Block Connectors in the system circuit.
Example : Connector "1" is described and is installed on the left side of the instrument panel.
S: Indicates the reference showing the position on the vehicle of J/B and Wire Harness in the system circuit.
Example Connector "3C" connects the Instrument Panel Wire and JIB No.3. It is described and is installed on the instrument panel left side.
T: Indicates the reference describing the wiring harness and wiring harness connector (the female wiring harness is shown first, followed by the male
wiring harness).
Example : Connector "IE" connects the floor wire (female) and Instrument panel wire (male). It is described and is installed on the left side kick
panel.
