DESCRIPTION The cruise control main switch is used to turn the cruise control system on and off, as well as operate 7 functions: SET, - (COAST), TAP-DOWN, RES (RESUME), + (ACCEL), TAP-UP and CANCEL. The SET, TAP-DOWN and - (COAST) functions, and the RES (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 the direction of each arrow and turns off after releasing it. The internal contact points of the cruise control main switch turn on with switch operation. Then the ECM reads the voltage value that has been changed by the switch operation to control the SET, - (COAST), RES (RESUME), + (ACCEL), and CANCEL functions. WIRING DIAGRAM  CAUTION / NOTICE / HINT NOTICE: The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System. Click here PROCEDURE
