DIAGNOSIS SYSTEM (LOW TIRE PRESSURE WARNING CONTROL UNIT)
DIAGNOSIS SYSTEM (LOW TIRE PRESSURE WARNING CONTROL
UNIT)
Diagnosis Description INFOID:0000000004958171
Description
During driving, the transmitter installed at each road wheel transmits the tire pressure information signal to the
receiver. The receiver receives the tire pressure signal and transmits it to the low tire pressure warning control
unit. The low tire pressure warning control unit judges whether or not the tire pressure is OK based on the tire
pressure information signal, and if it judges that the tire pressure is low, it transmits the information via CAN
communication to the BCM.
After receiving the tire pressure malfunction information via CAN communication, the BCM transmits the tire
pressure malfunction information via CAN communication to the combination meter.
After receiving the tire pressure information via CAN communication from the BCM, the combination meter illuminates
the low tire pressure warning lamp in order to warn the driver.
Self-diagnosis procedure
1. Initiate diagnosis mode by short-circuiting the low tire pressure warning check switch to the ground.
2. The blinking pattern of the low tire pressure warning lamp indicates the conditions of the malfunction.
NOTE:
If the low tire pressure warning lamp is blinking repeatedly at 5 Hz, there is no malfunction occurring in the
system.

U1000 CAN COMM CIRCUIT
Description INFOID:0000000004958205
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex
communication line with high data communication speed and excellent error detection ability. Many electronic
control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit communicates data but selectively reads required data only.
