Troubleshooting
4.3-9
DTC of tire pressure monitoring system (TPMS)
Recommended
countermeasures
Low power of power system
High power supply voltage of
power system
Reduce the power supply
voltage.
Effective sensor ID not
detected
1. ID not learned
2. Failure to read ID from
EEPROM
1. Re-learn the ID.
2. Replace the receiver
module.
Effective standard pressure not
detected
1. Standard pressure not set
2. Failure to read standard
pressure from EEPROM
1. Reset the standard pressure.
2. Replace the receiver
module.
Left front wheel failure to
receive tire pressure data
1.Sensor failed
2. Signal at the position that is
blocked by the obstacle
1. Replace the sensor.
2. Test if receiving can be
recovered when the vehicle is
running.
Low battery power of left front
wheel sensor
Sensor battery power lower
than 2.1 V
Left rear wheel failure to
receive tire pressure data
1. Sensor failed
2. Signal at the position that is
blocked by the obstacle
1. Replace the sensor.
2. Test if receiving can be
recovered when the vehicle is
running.
Low battery power of left rear
wheel sensor
Sensor battery power lower
than 2.1 V
Right front wheel failure to
receive tire pressure data
1.Sensor failed
2. Signal at the position that is
blocked by the obstacle
1. Replace the sensor.
2. Test if receiving can be
recovered when the vehicle is
running.
Low battery power of right front
wheel sensor
Sensor battery power lower
than 2.1 V
Right rear wheel failure to
receive tire pressure data
1. Sensor failed
2. Signal at the position that is
blocked by the obstacle
1. Replace the sensor.
2. Test if receiving can be
recovered when the vehicle is
running.
Low battery power of right rear
wheel sensor
Sensor battery power lower
than 2.1 V
Node off because of trigger of
error frames
Check communication circuit
for abnormality, such as CANH
and CANL short circuit, etc.
Vehicle speed signal lost
ESC failed or disconnection,
instrument failed or
disconnection, or CAN wire
harness fault
Check the CAN wire harness,
instrument and ESC.
Instrument communication loss
Instrument failed or
disconnection, or CAN wire
harness fault
Check the CAN wire harness
and the instrument.
Software check code fault
