Pattern Select Switch Circuit
Pattern Select Switch CircuitDESCRIPTION
The ECM receives tow/haul pattern select switch information and performs the tow/haul control. While the tow/haul control is operating, in contrast to normal mode, low gears are used to increase engine braking and towing power, reduce frequent shifts, and improve driveability. The tow/haul control includes throttle control, shift schedule control, wide open throttle shift timing control and AI-SHIFT control. Tow/haul mode only operates when the shift lever is in the D position and the tow/haul pattern select switch is ON.
HINT:
^ The tow/haul pattern select switch is a momentary-type switch.
^ In order to cancel tow/haul mode, push the tow/haul pattern select switch again or turn the ignition switch OFF.
