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". | |

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.)

P0643 sensor power supply
Description
ECM supplies a voltage of 5 V to some of the sensors systematically divided
into 2 groups, respectively.
Accordingly, when a short circuit develops in a sensor power source, a
malfunction may occur simultaneously
in the sensors belonging to the same group as the short-circuited ...
