Troubleshooting DTC of tire pressure monitoring system (TPMS) 4.3-9 Trouble code DTC Description Fault causes Recommended countermeasures U3003 Low battery voltage Low power of power system Charge High battery voltage High power supply voltage of power system Reduce the power supply voltage. B1700 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. B1701 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.
B1702 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 Replace the sensor. B1703 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 Replace the sensor.
B1704 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 Replace the sensor. B1705 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 Replace the sensor.
U0001 CAN bus off Node off because of trigger of error frames Check communication circuit for abnormality, such as CANH and CANL short circuit, etc. U0121 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. U0155 Instrument communication loss Instrument failed or disconnection, or CAN wire harness fault Check the CAN wire harness and the instrument. U0390 Software check code fault Software updated Update the software.
