Pattern Select Switch Circuit [08/2015 - 08/2017]: Description

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 D 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.
