Title: CRUISE CONTROL: CRUISE CONTROL SYSTEM: Cruise Control Switch Circuit; 2015 MY Tundra

Cruise Control Switch Circuit
DESCRIPTION
The cruise control main switch operates 7 functions: SET, COAST, TAP-DOWN, RESUME, ACCEL, TAP-UP, and
CANCEL. The SET, TAP-DOWN and COAST functions, and the RESUME, TAP-UP and ACCEL functions are
operated with the same switch. The cruise control main switch is an automatic return type switch which turns
on only while operating it in each arrow direction and turns off after releasing it. The internal contact point of
the cruise control main switch is turned on with the switch operation. Then the ECM reads the resistance value
that has been changed by the switch operation to control SET, COAST, RESUME, ACCEL and CANCEL.
