CRUISE CONTROL SYSTEM - Cruise Control Switch Circuit |
DESCRIPTION
This circuit sends signals to the ECM depending on the cruise control main switch condition. The battery supplies positive (+) battery voltage to the cruise control main switch. Then terminal CCS of the ECM receives the voltage according to the switch condition.
