DESCRIPTION

When the speed limiter main switch is turned on, the ECM illuminates the speed limiter indicator light and activates the speed limiter system. Each control of the speed limiter system can be activated by operating the cruise control switch. When the cruise control system is operating, the speed limiter system will not activate.
