Tire Monitoring System: Service and Repair
System Initialization ModeTo 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, the ECU must be initialized. To do this, press the tire pressure warning standardization 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 to the standard value
Note: Adjust the tire pressure according to the temperature of the environment in which the vehicle is to be operated.
2. Turn ON the ignition switch with the vehicle stopped.
3. If the low tire pressure warning light turns on, push the tire pressure warning reset switch for a few seconds, then the light turns off.
4. Press the tire pressure warning reset switch until the low tire pressure warning light blinks three times.
5. After finishing the above operation and start the usual driving, the ECU automatically stops the initialization and starts the tire pressure monitoring.
Note: Initialization is completed after driving at the speeds of 30 km/h (19 mph) 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 50km/h (31 mph) and 100 km/h (62 mph).
- The roads are dry, smooth and straight.
- The number of passengers is 1 or 2 (including driver).
