Note
When replacing the combination meter assembly, make sure to replace it with a new one.
w/ Lane Departure Alert System:
When replacing the Forward recognition camera, make sure to replace it with a new one.
w/ Pre-collision System:
When replacing the driving support ECU assembly, make sure to replace it with a new one.
Recognition code registration is necessary when replacing the main body ECU (multiplex network body ECU).
If the main body ECU (multiplex network body ECU) is replaced, refer to registration.
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

Tech Tips
*A: Items for consideration regarding ambient temperature display valueThe display value of the ambient temperature around the sensor changes due to the effects of heat radiated from the engine room and vehicle speed.
Depending on the driving status, the ambient temperature of the air surrounding the vehicle and the displayed value are different and the speed at which the displayed value updates is delayed. However, this is not a malfunction. When the vehicle is stopped or being driven at a low speed, the value is not updated to a higher temperature in order to minimize the effects of the radiated heat from the engine on the auto air conditioning control. Since the same adjustment occurs while the vehicle is being driven at medium to high speeds, updating to a higher temperature is delayed. However, the value is updated to a lower temperature regardless of the vehicle speed.
