Problem Symptoms Table [11/2018 - 12/2021]
NOTE:
- If no problem symptoms are found when a DTC is output in the DTC check on the lane control system, check each symptom by checking the suspected areas in the order they are listed.
- When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
