Low Tire Pressure Indicator: Service and Repair
System Initialization Mode
To enable this system to detect a low tire pressure, the normal tire pressure of the tires on the disc wheels that the vehicle currently uses is stored in
memory in the tire pressure monitor ECU. Therefore, if a tire or disc wheel is replaced or rotated, the ECU must be initialized. To do this, press the
tire pressure warning reset switch that is located below the driver side of the instrument panel, which transfers the system to the system initialization
mode and initializes the ECU.
The tire pressure monitor ECU can be initialized as follows:
*1: Adjust the tire pressure according to the temperature of the environment the vehicle is usually operated in.
*2: Initialization in completed after driving at the speeds of 19 mph (30 km/h) or over for more than one hour.
If the following driving conditions are satisfied, initialization will be completed in about one hour.
-
The vehicle speed is between 31 mph (50 km/h) and 62 mph (100 km/h).
-
The roads are dry, smooth and straight.
-
The number of passengers is 1 or 2 (including driver).
