Supra Liftback L6-2997cc 3.0L DOHC MFI Twin-Turbo (1997)
Stop Light: Description and Operation
Current is applied always through 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 8 of the Light Failure Sensor, and also flows through the rear
light 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 from
TERMINAL 7 of the Light Failure Sensor to TERMINAL 2 changes, so the Light Failure Sensor detects the disconnection and the warning
circuit of the Light Failure Sensor is activated.
As a result, current flows from TERMINAL 4 of the Light Failure Sensor --> TERMINAL 11 --> GROUND and turns the rear light warning
light ON. By pressing the brake pedal, the current flowing to TERMINAL 8 of the Light Failure Sensor keeps the warning circuit on holding and
keeps the Warning Light ON until the Ignition SW is turned OFF.
