Traction Control - Toyota Supra 2015 Wiring Diagram Manual

SYSTEM OUTLINE
TRACTION CONTROL IS THE SYSTEM TO REALIZE A FAVORABLE ACCELERATOR CONTROLABILITY BY MAKING
THE ENGINE OUTPUT MOST APPROPRIATE FOR THE ACCELERATION UNDER EACH DRIVING CONDITION

THIS IS THE SWITCH TO STOP THE OPERATION OF SLIP CONTROL. AFTER STARTING THE ENGINE, PRESSING THE
SWITCH ONE TIME UNDER THE CONDITION THAT THE SNOW INDICATOR DOES NOT LIGHT ON, MAKES IT IN THE
OPERATION STOP CONDITION (OFF), AND PRESSING IT ONE MORE TIME MAKES IT IN THE OPERATION WAITING
CONDITION. IN ADDITION, RESTARTING AFTER THE ENGINE STOP MAKES IT IN THE OPERATION WAITING
CONDITION WITHOUT CONCERNING THE TRACTION OFF SW.

AND SNOW INDICATOR LIGHT COMES ON. IN ADDITION, RESTARTING AFTER THE ENGINE STOP MAKES IT ALWAYS
IN NORMAL CONDITION (AUTO MODE) WITHOUT CONCERNING THE SNOW MODE SW CONDITION. PRESSING THE
SNOW MODE SW UNDER OPERATION PROHIBITION CONDITION OF THE TRACITION (TRAC OFF INDICATOR LIGHTS
ON.) CANCELS THE OPERATION PROHIBITION OF THE TRACTION AND ALSO FIXES IT AT LOW
(TRAC OFF INDICATOR LIGHT)
