Note:  
     For safety reasons, the instruction from the 
accelerator pedal sensor (potentiometer) to the 
ECM to open the throttle valve is suppressed 
when brake is being operated. This requires the 
brake light switch signal and also the brake pedal 
switch signal in the control module. If brake pedal 
is operated with accelerator pedal constantly 
depressed, engine is immediately regulated 
down to idle speed. A faulty switch can lead to 
undesired regulation.
