Toyota Camry (XV70): Cruise SET Indicator Light Circuit
DESCRIPTION
The ECM illuminates the cruise SET indicator by sending request signals to the combination meter assembly via CAN communication. The cruise SET indicator illuminates when the dynamic radar cruise control system is controlling vehicle speed. If the cruise SET indicator is not operating correctly, check for CAN communication DTCs before troubleshooting this circuit.
CAUTION / NOTICE / HINT
CAUTION:
Observe the following items for safety reasons when using the Techstream:
- Before using the Techstream, read the instruction manual.
- 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.
NOTICE:
- Before replacing the ECM, refer to Registration.
