SNOW MODE SWITCH
Revision: 2005 July 2005 FX
SNOW MODE SWITCHPFP:25130
DescriptionABS00A2I
The snow mode switch signal is sent to the “unified meter and A/C amp.” from the snow mode switch. The
“unified meter and A/C amp.” then sends the signal to the ECM by CAN communication line.
The snow mode is used for driving or starting the vehicle on snowy roads or slippery areas. If the snow mode
is activated, the vehicle speed will not be accelerated immediately than your original pedal in due to avoid the
vehicle slip. In other words, ECM controls the rapid engine torque change by controlling the electric throttle
control actuator operating speed.
