Cruise Main Indicator Light Circuit: Description

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

The ECM detects a cruise control switch signal and sends it to the combination meter via CAN. Then the CRUISE main indicator light comes on.
The CRUISE main 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.
