Component Parts Location
No. | Component parts | Function |
1 | Combination meter | The combination meter receives tire pressure status from the BCM via CAN communication. The combination meter will display the low tire pressure warning lamp when a low tire pressure or system malfunction is detected by the BCM. |
2 | Information display (in combination meter) | Refer to WT-7, "Information Display". |
3 | ABS actuator and electric unit (control unit) | Mainly transmits the following signals to BCM via CAN communication
|
4 | Front wheel sensor LH | Refer to BRC-10, "Wheel Sensor and Sensor Rotor". |
5 | BCM | Refer to WT-7, "BCM". |
6 | Rear wheel sensor LH | Refer to BRC-10, "Wheel Sensor and Sensor Rotor". |
7 | Rear wheel sensor LH (with AWD) | Refer to BRC-10, "Wheel Sensor and Sensor Rotor". |
8 | Tire pressure sensor | Refer to WT-7, "Tire Pressure Sensor". |
BCM
The BCM reads the air pressure signal received by the remote keyless entry receiver (without Intelligent Key System) or intelligent key receiver (with Intelligent Key System). In addition, the BCM also uses the outside key antennas (driver side, passenger side and rear bumper) to identify the location of the tire pressure sensors. The BCM has a self-diagnosis function used to detect system malfunctions.
Information Display
A low tire pressure warning or flat tire warning is shown on the vehicle information display when they are transmitted from BCM to combination meter via CAN communication.
Condition | Vehicle information displ | |
Ignition switch OFF | Not indicated | |
Ignition switch ON | Low tire pressure warning lamp remains ON after blinking for one minute. [Tire Pressure Monitoring System (TPMS) malfunction.] | Not indicated |
Ignition switch ON | Low tire pressure warning lamp remains ON. (low tire pressure) | Indicated |
Ignition switch ON | Flat tire warning | Indicated |
Tire Pressure Sensor
The tire pressure sensor (1) integrated with a valve is installed on a wheel (2), and transmits a detected air pressure and temperature signal by radio wave.
