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
Observe the following items for safety reasons when using GTS:
Before using the GTS, read the instruction GTS.
Prevent the GTS cable from being caught on the pedals, shift lever or steering wheel when driving with the GTS connected to the vehicle.
When driving the vehicle for testing purposes, 2 people are required. One person should operate the GTS while the other drives the vehicle.
Before replacing the ECM, refer to Service Bulletin.
When replacing the driving support ECU assembly, always replace it with a new one. If a driving support ECU assembly which was installed to another vehicle is used, the information stored in the driving support ECU assembly will not match the information from the vehicle. As a result, a DTC may be stored.
