DESCRIPTION The ECM
illuminates the cruise control SET indicator by sending indicator output
demand signals to the combination meter assembly via CAN communication.
The cruise control SET indicator illuminates when the dynamic radar
cruise control system is controlling vehicle speed. The cruise SET
indicator light circuit uses CAN communication. If the cruise control
SET indicator is not functioning correctly, check for CAN communication
DTCs before troubleshooting this circuit. CAUTION / NOTICE / HINT
CAUTION: Observe the following items for safety reasons when using Techstream:
- Before using the Techstream, read the instruction Techstream.
- Prevent the Techstream cable from being caught on the pedals, shift
lever or steering wheel when driving with the Techstream connected to
the vehicle.
- When driving the vehicle for testing purposes, 2 people are required.
One person should operate the Techstream while the other drives the
vehicle.

vehicle is used, the information stored in it will not match the
information from the vehicle and a DTC may be stored.
