Windshield wiper de-icer
This feature is used to prevent ice from building up on the windshield
and wiper blades.
On/off
The windshield wiper de-icer will
automatically turn off after approximately
15 minutes. Pressing the
switch again also turns the de-icer
off.
Operating conditions
Vehicles without a smart ...
Input speed sensor circuit no signal
Description
This sensor detects the rotation speed of the turbine, which shows the input
revolution of the transaxle. By
comparing the input speed signal (nt) with the counter gear speed sensor signal
(nc), the ecm detects
the shift timing of the gears and controls the engine torque and ...
