|
|||
| The low tire pressure warning lamp blinks once. |
|
Wake-up operation for all tire pressure sensors at wheels is not completed. | Perform the ID registration for all tire pressure sensors at wheels. Refer to Work Procedure. | |
| Hazard warning lamp |
The hazard warning lamp does not blink twice when the tire pressure sensor is activated. Or the buzzer does not sound. |
— | The tire pressure sensor activation tool does not activate. | Replace the battery in the tire pressure sensor activation tool. |
| Ignition switch OFF when the tire pressure sensor wake-up operation is performed. | Ignition switch ON when performing the tire pressure sensor wake-up operation. | |||
| The tire pressure sensor activation tool is not used in the correct position. | Operate the tire pressure sensor activation tool in the correct position when performing the wake-up operation. | |||
| The tire pressure sensor is already waked up. | No procedure. |
NOTE:
If tire pressure sensor wake-up operation is not completed for two or more tire pressure sensors, the applicable low tire pressure warning lamp blinking patterns are displayed continuously.
(Example: Blinks once/OFF/blinks 3 times = Wake-up operation is not completed at the front left wheel and rear right wheel tire pressure sensors.)
