Toyota Venza: Cruise SET Indicator Light Circuit

Toyota Venza Service Manual / Cruise Control / Cruise Control System / Cruise SET Indicator Light Circuit

DESCRIPTION

The ECM detects a cruise control switch signal and sends it to the combination meter assembly through CAN. Then the SET indicator light comes on.
The SET indicator light circuit uses CAN for communication. If there is a malfunction in this circuit, check for DTCs in the CAN communication system before troubleshooting this circuit.
