Toyota RAV4 (XA40) 2013-2018 Service Manual: Cruise control switch circuit
Description
This circuit sends signals to the ecm depending on the cruise control switch condition. The battery supplies positive (+) battery voltage to the cruise control switch. Then terminal ccs of the ecm receives the voltage according to the switch condition.
