Toyota Sienna Service Manual: Cruise Main Indicator Light Circuit
DESCRIPTION
- The ECM detects a cruise control switch signal and sends it to the combination meter through CAN and BEAN. Then the CRUISE main indicator light comes on.
- The CRUISE main indicator light circuit uses CAN and BEAN for communication. If there is a malfunction in this circuit, check for DTCs in the CAN communication system and multiplex communication system before troubleshooting this circuit.
