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.)
Calibration of decel G sensor
Description
CAUTION:
Always perform the decel G sensor calibration before driving when the following
operation is performed.
NOTE:
Yaw rate/side/decel G sensor calibration is performed when performing the decel
G sensor calibration.
Work Procedure
Decel G sensor calibration
CAUTION: ...
Satellite radio reception (if so equipped)
When the satellite radio is used for the first time
or the battery has been replaced, the satellite
radio may not work properly. This is not a malfunction.
Wait more than 10 minutes with satellite
radio ON and the vehicle outside of any metal or
large building for satellite radio to receive a ...
U1000 CAN COMM CIRCUIT
Description
CAN communication allows a high rate of information transmission through the
two communication lines
(CAN-H line and CAN-L line) connecting various control units in the system. Each
control unit transmits/
receives data but selectively reads required data only.
