CRUISE CONTROL SYSTEM Cruise Control Switch Circuit

DESCRIPTION

The circuit sends a signal to the ECM depending on the cruise control switch condition. The battery supplies positive (+) battery voltage to the cruise control switch. Terminal 41 (CCS) of the ECM receives the voltage which varies according to the switch condition.
