LOW TIRE PRESSURE WARNING LAMP SYMPTOM CHART
Diagnosis items | Symptom (Power switch ON) | Low tire pressure warning lamp | Cause | Action |
Low tire pressure warning lamp | The low tire pressure warning lamp illuminates for 1 second, then turns OFF. | Wake-up operation for all tire pressure sensors at wheels is completed. | No system malfunctions | |
The low tire pressure warning lamp repeats blinking ON for 2 seconds and OFF for 0.2 seconds. | 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 WT-21, "Work Procedure". | ||
The low tire pressure warning lamp blinks once. | The front left tire pressure sensor is not activated. | Perform the ID registration for the tire pressure sensor at front left wheel. Refer to WT-21, "Work Procedure". | ||
The low tire pressure warning lamp repeats blinking twice. | The front right tire pressure sensor is not activated. | Perform the ID registration for the tire pressure sensor at front right wheel. Refer to WT-21, "Work Procedure". | ||
The low tire pressure warning lamp repeats blinking for 3 times. | The rear right tire pressure sensor is not activated | Perform the ID registration for the tire pressure sensor at rear right wheel. Refer to WT-21, "Work Procedure". | ||
The low tire pressure warning lamp repeats blinking for 4 times. | The rear left tire pressure sensor is not activated. | Perform the ID registration for the tire pressure sensor at rear left wheel. Refer to WT-21, "Work Procedure". | ||
The low tire pressure warning lamp turns ON and stays illuminated. | Low tire pressure | Check the tire pressure for all wheels and adjust to the specified value. Refer to WT-65, "Tire Air Pressure". | ||
The low tire pressure warning lamp repeats blinking at 0.5-second intervals for 1 minute, and then stays illuminated. | The combination meter fuse is open or removed (or pulled out). | Check and install the combination meter fuse. If necessary, replace the fuse. | ||
The BCM harness connector is removed. | Check the connection conditions of the BCM harness connector, and repair if necessary. | |||
Tire Pressure Monitoring System (TPMS) malfunction. |
|
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.)
